Duplex Stainless SteelAL 2205™ Alloy(UNS S31803 and S32205)Data are typical and should not be construed as maximum or minimum valuesfor specification or for final design. Data on any particular piece of material may ™ Trademark of ATI Properties, Inc.GENERAL PROPERTIESThe AL 2205™ alloy (UNS S31803 and/or S32205) is a nitrogen-enhanced duplex stainless steel alloy. The nitrogen serves to significantly improve the corrosion resistance of the alloy; especially in the welded condition.Earlier duplex alloys have had moderate resistance to general corrosion and chloride stress corrosion cracking,but suffered a substantial loss of properties when used in the as-welded condition. To impart the metallurgical benefits of nitrogen to both improved corrosion performance and as-welded properties, the AL 2205 alloy is produced to a 0.15% minimum nitrogen content compared to the ASTM range of 0.08-0.20% for S31803and 0.14-0.20% for S32205. The minimum Cr, Mo and Ni contents of AL 2205 alloy (22.0, 3.1 and 5.5%respectively) satisfy the requirements of both the UNS S31803 and S32205 composition specifications. The typical high Cr, Mo and Ni contents of AL 2205 alloy give it a high PRE N (Pitting Resistance Equivalent) of 35.8,further enhancing its corrosion resistance. The PRE N of AL 2205 alloy exceeds those of types 316L and 317L stainless steels.When heat-treated properly, the composition of AL 2205alloy produces a microstructure that consists of a nearly equal mixture of austenite and ferrite phases as shown in the photomicrograph above right. The microstructure and composition of the AL 2205 alloy provides corrosion resistance to many environments that is superior to Types 316 or 317, and a minimum yield strength that is more than double that of conventional austenitic stainless steels.The microstructure and phase balance of AL 2205 alloy have been designed to facilitate the production of pipe and tube products. All AL 2205 alloy is metallographically examined to ensure that the as-shipped product is essentially free from the presence of detrimentalprecipitate phases such as sigma.Duplex microstructure of AL 2205 ™ alloy. The ferrite phase appears darker than the austenite due to KOH etch. The ferrite content is 40% in this sample.COMPOSITIONThe AL 2205 alloy is the most widely used of the duplex stainless steels and is often used in the form of welded pipe or tubular components. The alloy has also been applied as a formed and welded sheet product in environ-ments where resistance to general corrosion and chloride stress corrosion cracking is important.Data are typical and should not be construed as maximum or minimum values for specification or for final design. Data on any particular piece of material may Stainless Steel Visit our Website atAL 2205™ Alloy SPECIFICATIONSPHYSICAL PROPERTIESMECHANICAL PROPERTIESTypical Room Temperature PropertiesTypical mechanical properties for annealed AL 2205 alloy material at room temperature are listed below:Technical Data BLUE SHEETData are typical and should not be construed as maximum or minimum values for specification or for final design. Data on any particular piece of material may The AL 2205 alloy has been approved for use under Section Vlll, Division 1 of the ASME Boiler and Pressure Vessel Code (for S31803) to a maximum temperature of 600°F (316°C). Use of S32205 is approved for nuclear construction by Code Case N-741. The strength of the AL 2205 alloy is indicated by the maximum allowable stress values given in the ASME Boiler and Pressure Vessel Code reproduced below, and compared to values for Type 316L stainless steel.Such relatively high maximum allowable stress values can be used advantageously in process unit design. The stress values that are given below apply to plate, sheet,strip, seamless tubing and pipe products. A factor of 0.85 is applied when considering welded tubing or pipe products.transition temperature can be substantially increased by exposing the alloy for extended periods of time at temperatures in the range from 650 to 1000°F (343-530°C). Consequently, this temperature range must be avoided in fabrication and service. Improper welding procedures, such as welding with straight chromium stainless steel filler metals, will increase the susceptibility of the weld to brittle impact behavior. The data presented below are from tests conducted on 3/8 inch (0.95 cm)thick AL 2205 unwelded plate samples in the annealed and rapidly cooled condition.Charpy impact energies far greater than the 40 ft-lb (54J) at -40°F (-40°C) minimum specified by ASTM A 923.AL 2205 alloy also passes the NORSOK minimum impact energy requirement at -46°F (-50°C) of 45J average and 35J single specimen minimum. If specified,this toughness will be demonstrated by test prior to shipment.Impact PropertiesDuplex AL 2205 alloy may undergo a transition from a ductile mode of fracture at higher temperatures to a brittle mode of fracture at lower temperatures when subjected to impact loading. The ductile-to-brittleData are typical and should not be construed as maximum or minimum values for specification or for final design. Data on any particular piece of material may Stainless Steel Visit our Website atAL 2205™ AlloyEffect of Elevated Temperature onMechanical PropertiesAn upper temperature limit of 600°F (316°C) has been placed on the use of AL 2205 alloy in the ASME Boiler and Pressure Vessel Code due to what is known as “885°F (475°C) Embrittlement.” This means that the ferrite phase of AL 2205 alloy may be embrittled after exposure to temperatures from 650 to 1000°F (343-538°C). The 885°F (475°C) embrittlement is reversible by heat treating the alloy at a temperature above 1100°F (590°C). However, another embrittling range exists from about 1000°F (538°C) to 1830°F (1000°C) due to the precipitation of excess phases that are detrimental to both impact and corrosion properties. A full anneal and rapid cooling treatment is required to eliminate the latter form of embrittlement and is also the preferred manner of relieving forming stresses and 885°F (475°C)embrittlement.Fatigue ResistanceThe AL 2205 alloy shows high resistance to fatigue. Its endurance limit at room temperature is about 45% of its tensile strength. Sheet bending fatigue data are shown below.severe boiling 42% magnesium chloride test. Nickel-containing austenitic stainless steels, on the other hand,are highly susceptible to stress corrosion cracking (SCC).The resistance of austenitic and ferritic stainless steels to chloride stress corrosion cracking has been corre-lated to the nickel content of the alloys. 1Duplex alloys behave in a manner that is a combination of the characteristics of the austenitic and ferritic phases that make up the alloy, as shown by the data below.Certain elements tend to partition into one of the two primary phases in duplex alloys. For example, the nickel content of the ferrite phase will be lower than that of the austenite phase relative to the bulk composition.Consequently, the ferrite phase in AL 2205 alloy will provide resistance to chloride stress corrosion cracking,making it substantially better than the standard 300series austenitic stainless steels.Therefore, duplex stainless steels are often preferred over austenitic stainless steels in applications where chloride SCC is a problem.*"Failed" indicates failure by chloride stress corrosion cracking in the time indicatedPitting and Crevice Corrosion ResistanceA relative ranking of the resistance to chloride-ion pitting and crevice corrosion can be made by using ASTM procedure G-48 (10% FeCl 3 ·6H 2O) and increasing the test temperature until the onset of crevice corrosion attack is observed. The temperature at which attack is first observed is called the critical crevice corrosion temperature and can be used as a relative measure of crevice corrosion resistance. The critical crevice corrosion temperature criterion is useful for ranking alloys, but does not necessarily indicate an absolute limiting temperature for the use of a particular alloy in chloride-bearing solutions.CORROSION PROPERTIESChloride Stress Corrosion Cracking ResistanceThe nickel-free ferritic steels are essentially immune to chloride stress corrosion cracking even in the extremelyA L 2205™ A lloy Sheet Bending fatigue020,00040,00060,00080,000100,000120,00010,000100,0001,000,00010,000,000C yclesS t r e s s (p s i )Technical Data BLUE SHEETData are typical and should not be construed as maximum or minimum values for specification or for final design.

Data on any particular piece of material may Stainless Steel Visit our Website atAL 2205™ Alloy © ATI Allegheny Ludlum 2008FABRICATION AND WELDINGWeldingThe AL 2205 alloy is designed to contain approximately equal amounts of ferrite and austenite in the annealed strip or plate product. Autogenous welding will increase the amount of ferrite present in the weldment and adjacent areas of the base metal. Subsequent annealing will tend to restore the balance of phases in the base metal. However, an annealed autogenous weld can be expected to contain slightly more ferrite than the corresponding base metal. A fully ferritic weldshould be avoided.HEAT AFFECTED ZONE OF WELDMicrostructure of an autogenous weld made in AL 2205 ™ alloy plate. The ferrite content of the base metal is 45% and the weld contains over 50% ferrite. Etchant - KOH.Matching filler metals are commercially available to weld the AL 2205 alloy. Such filler metals (AWS E2209)contain more nickel than the base metal in order to produce a phase balance within the weld that is approximately the same as the base metal. When AL 2205 alloy is welded to different metals, a filler metal should be chosen that contains a quantity of austenite forming elements that is sufficient to produce a partially or fully austenitic weld. The large, fully ferritic grains that may form in a weld made from ferritic fillers may lower impact ductility at room temperature.Heat TreatmentThe AL 2205 alloy should be annealed between 1870and 2010°F (1020-1100°C) and cooled quickly. Anneal-ing near 2010°F will increase the amount of ferrite present in the microstructure compared to that result-ing from annealing near 1870°F. The graph following provides additional information.FormingThe AL 2205 alloy can be successfully cold-bent and expanded. Greater loads will be required to deform the alloy because of the higher strength of this duplex alloy in comparison to conventional austenitic materials. The ferrite phase within the duplex structure of the AL 2205alloy results in an elongation that is less than that of a comparable austenitic stainless steel. The alloy should be bent to more generous bend radii than fully austenitic materials. A minimum bend radius of at least twice the material thickness should be used.Furthermore, the degree to which AL 2205 alloy tubing can be expanded into tubesheets is restricted by the lower tensile elongation of the material in comparison to conventional austenitic materials. The strength of the AL 2205 alloy is high relative to most tube sheet materials. Consequently, care must be taken to produce tight roller expanded joints between AL 2205 alloy tubing and other tube sheet materials.Heavily cold-bent sections should be fully annealed (not just stress-relieved) after bending whenever there is the potential for stress corrosion cracking (SCC) in the service environment. Stress relief heat treatments in the 600 to 1700°F (316-926°C) range adversely affect the properties of the alloy and should not be considered.References for Additional Details(1) Copson, H.

Z5U,X7R,X5R,NPO陶瓷电容

Z5U,X7R,X5R,NPO陶瓷电容

下面我们仅就常用的NPO、X7R、Z5U和Y5V来介绍一下它们的性能和应用以及采购中应注意的订货事项以引起大家的注意。

不同的公司对于上述不同性能的电容器可能有不同的命名方法,这里我们引用的是AVX公司的命名方法,其他公司的产品请参照该公司的产品手册。

NPO、X7R、Z5U和Y5V的主要区别是它们的填充介质不同。

在相同的体积下由于填充介质不同所组成的电容器的容量就不同,随之带来的电容器的介质损耗、容量稳定性等也就不同。

所以在使用电容器时应根据电容器在电路中作用不同来选用不同的电容器。

一 NPO电容器NPO是一种最常用的具有温度补偿特性的单片陶瓷电容器。

它的填充介质是由铷、钐和一些其它稀有氧化物组成的。

NPO电容器是电容量和介质损耗最稳定的电容器之一。

在温度从-55℃到+125℃时容量变化为0±30ppm/℃,电容量随频率的变化小于±0.3ΔC。

NPO电容的漂移或滞后小于±0.05%,相对大于±2%的薄膜电容来说是可以忽略不计的。

其典型的容量相对使用寿命的变化小于±0.1%。

NPO电容器随封装形式不同其电容量和介质损耗随频率变化的特性也不同,大封装尺寸的要比小封装尺寸的频率特性好。

下表给出了NPO电容器可选取的容量范围。

NPO电容器适合用于振荡器、谐振器的槽路电容,以及高频电路中的耦合电容。

二 X7R电容器X7R电容器被称为温度稳定型的陶瓷电容器。

当温度在-55℃到+125℃时其容量变化为15%,需要注意的是此时电容器容量变化是非线性的。

X7R电容器的容量在不同的电压和频率条件下是不同的,它也随时间的变化而变化,大约每10年变化1%ΔC,表现为10年变化了约5%。

X7R电容器主要应用于要求不高的工业应用,而且当电压变化时其容量变化是可以接受的条件下。

它的主要特点是在相同的体积下电容量可以做的比较大。

下表给出了X7R电容器可选取的容量范围。

三 Z5U电容器Z5U电容器称为”通用”陶瓷单片电容器。

Compliant with Small Form Pluggable (SFP) Multi Source Agreement (MSA) mechanical and electrical specifications for LC Duplex transceivers, ANSI Fibre Channel FC-PI, FC-PI-2 and com-patible with IEEE 802.3 for gigabit applications. The part is electrically interoperable with SFP conformant devices.As an enhancement to the conventional SFP interface defined in SFF-8074i, the AFBR-57R5APZ is compliant to SFF-8472 (digital diagnostic interface for optical trans-ceivers). Using the 2-wire serial interface defined in the SFF-8472 MSA, the AFBR-57R5APZ provides real time temperature, supply voltage, laser bias current, laser average output power and received input power. This information is in addition to conventional SFP base data. The digital diagnostic interface also adds the ability to disable the transmitter (TX_DISABLE), monitor for Trans-mitter Faults (TX_FAULT), and monitor for Receiver Loss of Signal (RX_LOS).Applications• Fibre channel systems – Director class switches – Fabric switches – HBA cards• Disk and tape drive arraysRelated Products• AFBR-59R5LZ: 850 nm +3.3 V LC SFF 2x7 for 4.25/2.125/1.0625 GBd Fibre ChannelInstallationThe AFBR-57R5APZ can be installed in any SFF-8074i compliant Small Form Pluggable (SFP) port regardless of host equipment operating status. The AFBR-57R5APZ is hot-pluggable, allowing the module to be installed while the host system is operating and on-line. Upon insertion, the transceiver housing makes initial contact with the host board SFP cage, mitigating potential damage due to Electro-Static Discharge (ESD).Digital Diagnostic Interface and Serial Identification The 2-wire serial interface is based on ATMEL AT24C01A series EEPROM protocol and signaling detail. Conven-tional EEPROM memory, bytes 0-255 at memory address 0xA0, is organized in compliance with SFF-8074i. New digital diagnostic information, bytes 0-255 at memory address 0xA2, is compliant to SFF-8472. The new diag-nostic information provides the opportunity for Predic-tive Failure Identification, Compliance Prediction, Fault Isolation and Component Monitoring.Predictive Failure IdentificationThe AFBR-57R5APZ predictive failure feature allows a host to identify potential link problems before system perfor-mance is impacted. Prior identification of link problems enables a host to service an application via “fail over” to a redundant link or replace a suspect device, main-taining system uptime in the process. For applications where ultra-high system uptime is required, a digital SFP provides a means to monitor two real-time laser metrics associated with observing laser degradation and pre-dicting failure: average laser bias current (Tx_Bias) and average laser optical power (Tx_Power).Compliance Prediction Compliance prediction is the ability to determine if an optical transceiver is operating within its operating and environmental requirements. AFBR-57R5APZ devices provide real-time access to transceiver internal supply voltage and temperature, allowing a host to identify potential component compliance issues. Received optical power is also available to assess compliance of a cable plant and remote transmitter. When operating out of requirements, the link cannot guarantee error free transmission.Fault IsolationThe fault isolation feature allows a host to quickly pinpoint the location of a link failure, minimizing downtime. For optical links, the ability to identify a fault at a local device, remote device or cable plant is crucial to speeding service of an installation. AFBR-57R5APZ real-time monitors of Tx_Bias, Tx_Power, Vcc, Temperature and Rx_Power can be used to assess local transceiver current operating conditions. In addition, status flags Tx_Disable and Rx Loss of Signal (LOS) are mirrored in memory and available via the two-wire serial interface. Component MonitoringComponent evaluation is a more casual use of the AFBR-57R5APZ real-time monitors of Tx_Bias, Tx_Power, Vcc, Temperature and Rx_Power. Potential uses are as debugging aids for system installation and design, and transceiver parametric evaluation for factory or field qualification. For example, temperature per module can be observed in high density applications to facilitate thermal evaluation of blades, PCI cards and systems.Figure 1. Transceiver functional diagram.Transmitter SectionThe transmitter section includes consists of the Transmit-ter Optical SubAssembly (TOSA) and laser driver circuitry. The TOSA, containing an 850 nm VCSEL (Vertical Cavity Surface Emitting Laser) light source, is located at the optical interface and mates with the LC optical connector. The TOSA is driven by a custom IC which uses the incoming differential high speed logic signal to modulate the laser diode driver current. This Tx laser driver circuit regulates the optical power at a constant level provided the incoming data pattern is dc balanced (8B/10B code, for example).Transmit Disable (Tx_Disable)The AFBR-57R5APZ accepts a TTL and CMOS compat-ible transmit disable control signal input (pin 3) which shuts down the transmitter optical output. A high signal implements this function while a low signal allows normal transceiver operation. In the event of a fault (e.g. eye safety circuit activated), cycling this control signal resets the module as depicted in Figure 4. An internal pull up resistor disables the transceiver transmitter until the host pulls the input low. Host systems should allow a 10 ms interval between successive assertions of this control signal. Tx_Disable can also be asserted via the two-wire serial interface (address A2h, byte 110, bit 6) and monitored (address A2h, byte 110, bit 7).The contents of A2h, byte 110, bit 6 are logic OR’d with hardware Tx_Disable (pin 3) to control transmitter operation.Transmit Fault (Tx_Fault)A catastrophic laser fault will activate the transmitter signal, TX_FAULT, and disable the laser. This signal is an open collector output (pull-up required on the host board). A low signal indicates normal laser operation and a high signal indicates a fault. The TX_FAULT will be latched high when a laser fault occurs and is cleared by toggling the TX_DISABLE input or power cycling the transceiver. The transmitter fault condition can also be monitored via the two-wire serial interface (address A2, byte 110, bit 2).Eye Safety CircuitThe AFBR-57R5APZ provides Class 1 (single fault tolerant) eye safety by design and has been tested for compliance with the requirements listed in Table 1. The eye safety circuit continuously monitors the optical output power level and will disable the transmitter upon detecting an unsafe condition beyond the scope of Class 1 certifica-tion. Such unsafe conditions can be due to inputs from the host board (Vcc fluctuation, unbalanced code) or a fault within the transceiver.Receiver SectionThe receiver section includes the Receiver Optical Sub-Assembly (ROSA) and the amplification/quantization circuitry. The ROSA, containing a PIN photodiode and custom transimpedance amplifier, is located at the optical interface and mates with the LC optical connector. The ROSA output is fed to a custom IC that provides post-amplification and quantization.Receiver Loss of Signal (Rx_LOS)The post-amplification IC also includes transition detection circuitry which monitors the ac level of incoming optical signals and provides a TTL/CMOS compatible status signal to the host (pin 8). An adequate optical input results in a low Rx_LOS output while a high Rx_LOS output indicates an unusable optical input. The Rx_LOS thresholds are factory set so that a high output indicates a definite optical fault has occurred. Rx_LOS can also be monitored via the two-wire serial interface (address A2h, byte 110, bit 1).Functional Data I/OThe AFBR-57R5APZ interfaces with the host circuit board through twenty I/O pins (SFP electrical connector) iden-tified by function in Table 2. The board layout for this interface is depicted in Figure 6.The AFBR-57R5APZ high speed transmit and receive interfaces require SFP MSA compliant signal lines on the host board. To simplify board requirements, biasing resistors and ac coupling capacitors are incorporated into the SFP transceiver module (per SFF-8074i) and hence are not required on the host board. The Tx_Disable, Tx_Fault, and Rx_LOS lines require TTL lines on the host board (per SFF-8074i) if used. If an application chooses not to take advantage of the functionality of these pins, care must be taken to ground Tx_Disable (for normal operation). Figure 2 depicts the recommended interface circuit to link the AFBR-57R5APZ to supporting physical layer ICs. Timing for MSA compliant control signals implemented in the transceiver are listed in Figure 4.

For information related to SFF Committee documentation visit www. . CautionThere are no user serviceable parts nor maintenance requirements for the AFBR-57R5APZ. All mechanical adjustments are made at the factory prior to shipment. Tampering with, modifying, misusing or improp-erly handling the AFBR-57R5APZ will void the product warranty. It may also result in improper operation and possibly overstress the laser source. Performance degradation or device failure may result. Connection of the AFBR-57R5APZ to a light source not compliant with ANSI FC-PI or IEEE 802.3 specifications, operating above maximum operating conditions or in a manner inconsis-tent with it’s design and function may result in exposure to hazardous light radiation and may constitute an act of modifying or manufacturing a laser product. Persons performing such an act are required by law to re-certify and re-identify the laser product under the provisions of U.S. 21 CFR (Subchapter J) and TUV.Regulatory ComplianceThe AFBR-57R5APZ complies with all applicable laws and regulations as detailed in Table 1. Certification level is dependent on the overall configuration of the host equipment. The transceiver performance is offered as a figure of merit to assist the designer. Electrostatic Discharge (ESD)The AFBR-57R5APZ is compatible with ESD levels found in typical manufacturing and operating environments as described in Table 1. In the normal handling and operation of optical transceivers, ESD is of concern in two circumstances.The first case is during handling of the transceiver prior to insertion into an SFP compliant cage. To protect the device, it’s important to use normal ESD handling pre-cautions. These include use of grounded wrist straps, work-benches and floor wherever a transceiver is handled.The second case to consider is static discharges to the exterior of the host equipment chassis after installation. If the optical interface is exposed to the exterior of host equipment cabinet, the transceiver may be subject to system level ESD requirements.Table 1. Regulatory Compliance Feature Test Method Performance Electrostatic Discharge (ESD) MIL-STD-883C Class 1 (> 2000 Volts)to the Electrical Pins Method 3015.4Electrostatic Discharge (ESD) Variation of IEC 61000-4-2 Typically, no damage occurs with 25 kV when to the Duplex LC Receptacle the duplex LC connector receptacle is contacted by a Human Body Model probe.

The AFBR-57R5APZ’s compliance to these standards is detailed in Table 1. The metal housing and shielded design of the AFBR-57R5APZ minimizes the EMI challenge facing the equipment designer.EMI Immunity (Susceptibility)Due to its shielded design, the EMI immunity of the AFBR-57R5APZ exceeds typical industry standards.FlammabilityThe AFBR-57R5APZ optical transceiver is made of metal and high strength, heat resistant, chemical resistant and UL 94V-0 flame retardant plastic.Figure 2. Typical application configuration.Figure 3. Recommended power supply filter.3.3 VNOTE: INDUCTORS MUST HAVE LESS THAN 1 Ω SERIES RESISTANCE TO LIMIT VOLTAGE DROP TO THE SFP MODULE.Notes:1.

索尼Xperia Z5体验:颜色控请买单

索尼Xperia Z5体验:颜色控请买单

索尼Xperia Z5体验:颜色控请买单十几年前在商场橱柜中看到用保鲜膜包裹的各式各样的Walkman随身听构成了我对索尼的第一印象,索尼一直以来在颜色和工艺上保持着良好的质感,面对这类产品,忍不住想买的冲动俗称“长草”,这种种种产品遗留的印象构成了我对“索尼大法好”的理解。

索尼爱立信时代旗舰产品以X加数字命名,而更名索尼移动之后,旗舰系列变成了Z,与曾经的旗舰笔记本有所重叠,设计风格也从人体工程学的弧线变成了简洁全对称的硬朗“平板”式设计。

由于设计风格定型,索尼在每代产品所能做的改动不多,这种边框削平的做法功能上也是方便在侧边增加一枚指纹识别的电源按键,所以不能像前几代那样边框做得比较厚。

Z5的外观一定是人人见了都想摸一摸,与Z5 Premium镜面不同,Z5的光泽展现了索尼的传统磨砂质感,是通过玻璃内侧上色,又另在玻璃外侧做雾面处理完成,有很不错的光泽,索尼的LOGO和Xperia的LOGO分别用抛光和更高一级的磨砂进行区分。

这种表面工艺带来不错的手感,。

- 机身底部保留了挂绳孔,对部分人来说非常便利;- 隐藏式双扬声器(之前Z2还有隐藏式的LED呼吸灯,不知为何没保留),音效暂时比不过BoomSound,不过总归也解决了横向持握时扬声器容易被手遮挡的问题,缺点是容易积灰,然而如果你常用外放,音量开大一点能把灰尘“震出来”;- 2300W像素摄像头没有做成凸起的,LED补光灯尽管只给了一枚,然而以我的使用经验来说,无论一枚还是两枚,闪光灯拍出来的照片一般不能用;- 除了挂绳孔,索尼也是市场上为数不多的坚持在手机侧边设置相机按键的品牌,并且支持长按快速唤醒;- 音乐程序中集成Gracenote可以选择下载专辑封面和曲目信息,不过这项功能需要手动开启,而且无法更改现有的专辑格局;- 天气挂件很漂亮(如下截图)。

To remove the battery you must unscrew the front panel and un-plug the positive and negative connector . Be sure to fix very well the battery with the dedicate lock (tie plastic bands) to avoid the disconnection of it during the transport. It may cause the crash of some electronic parts. The battery is quite heavy. Use rechargeable 6 volts – 4A lead battery only.2.2| Battery ChargingWhen the BATTERY level tester leds are in red status recharge the batteryWith this automatic charger all 6V DC 2.2-10 Ah sealed lead acid batteries can be charged automatically.When the connected battery is completely charged, the current will be reduced to prevent overcharging. Due to the automatic voltage and current control the connected battery will always stay completely charged and at the same time the overcharging as well as the gas development will be prevented.A security circuit prevents that there is no voltage at the connecting pins as long as there is no battery connected.The charger has the following features:>> short circuit and wrong polarity prevention >> constant final charging current >> no charging with wrong connected polarity >> charging will only take place with correctly connected battery >>optical display for chargingOperating informationIn contrast to simple chargers the charging current of thisautomatic charger is not constant and depends on come components, for example the actual charging level of the battery, the age of the battery, the type of the battery and the capacity. Also it is important how much the battery has been discharged before. If the battery had been discharged with high currency then there will be in the beginning of the charging a high current, which decreases after a short period. This means that with rising voltage the charging current decreases.Towards the end of the charging (battery is full) normally the green light charging diminishes.With old batteries sometimes there might be a small current flowing (leakage current of the battery). Here the green light might be on, this is due to the strength of the current. With new batteries the light will diminish once the battery is full. The charger can charge different batteries with different capacities, the bigger the battery is, the longer the charging time will be. With smaller batteries the charging time will be shorter.For the charging itself it is not important if the battery is partly or completely discharged. The battery can stay connected to the charger for a long period. Full battery charging will require 12 hours (90%). Do not switch the unit immediately after end of battery charge and do it in a fresh and ventilated area.Usage of the charger1. Connect to the battery charger.2. Connect to the supply mains.3. After charging, disconnect thebattery charger from the mains. Thenremove from the battery charger.M105Digital w/battery level tester | M105D MARINER - rel. 1.3 8>> WarningThe product is short-term short circuit prevented! Longer lasting short circuits (longer than 1 min.) must be prevented under all circumstances, otherwise parts of the charger or the electronic might be overloaded.Attempting to charge other types of batteries may cause personal injury and damage to the charger if the supply cord of this equipment is damaged, it must only be replaced by the manufacturer or its service agent or similarly qualified person in order to avoid a hazard.During charging the M105 Digital must be placed in a well ventilated area. Make sure to have enough air supply!Make sure not to have any open fire, open light and glimmers close to the charged batteries (danger of explosion due to gas)!This charger is not intended for use by young children or infirm persons without supervision. Young children should be supervised to ensure that day do not play with the appliance.2.3 | Low Battery AlertThe M105 Digital is equipped with a unique low battery alert.When the batteries reach approximately 4,7 volts you will hear a short tone burst every 10 seconds. You should have approximately one half hour more service after you bear the low battery alert.>> WarningIt is recommended to ship M105Digital without battery installed, remove battery before shipping to prevent damages to holders in the event the units dropped.The battery should be disconnected if you intend to store the M105Digital for an extended time.2.4 | Battery level testerThe new M105 digital is equipped with an integrated battery control system. It allows you to recharge the battery only if necessary. When you see the red light turn on pleaserecharge the unit.M105Digital w/battery level tester | M105D MARINER - rel. 1.393.1| Operating the M105DigitalThe M105 Digital was designed to be portable and easy to operate.After you have properly installed the battery you are ready to set up your surface station.The M105 Digital is an ultrasonic digitized, through-water communication SYSTEM. It must be operated using water as the transmitting medium. You will be able to talk to all other divers and/or surface stations on the same frequency and within range. When you speak ,your voice is sent out in an Omni directional pattern via the transducer to all other transceivers. The transducer is the antenna which both sends out the signal and picks up incoming signals.The following is the recommended operating procedures1 | Ensure battery is property installed, fetish and the front panel is installed without pinching any wires.2 | Place the M105 Digital on a surface that is secure from boat action and where the transducer cable will not trip anyone or be damaged.3 |Open the front cover of the M105 and connect the transducer cable to the front panel . Switch on the unit. A short “beep” will be listened. If transducer cable is not plugged in the unit it will not switch on. When not using the M105 Digital , disconnect the transducer cable or switch off the unit. This will conserve battery power.4 | Lower the transducer into the water. If using Arraya boat, lower the transducer so it clears thehull. If the base station is set up on a beach, thetransducer should be suspended from a float. Underno circumstance should the transducer lay on thebottom.If you lay the transducer on the bottom,transmitting and receiving signal strength will bereduced. The result will be no range and weak or nocommunications. If a current is running, you mighthave to tie a weight to the transducers strengthmember.This will keep the transducer from flagging.10M105Digital w/battery level tester | M105D MARINER - rel. 1.3M105Digital w/battery level tester | M105D MARINER - rel. 1.311#U N D E R W A T E R N A T U R A L L YNote >> You must tie the weight to the transducers strength in only. Do not tie the weightto the transducer cable. The weight may damage the cable. After the weight is tied and secured to the strength member , lower the strength line with the weight and transducer into the water and tie off the strength line.5 | Connect the band-held microphone to the MIC receptacle.6 | Switch on the unit7 | Adjust the volume to a comfortable listening level.8 | If you want to use 12 volt boat power or an alternate power source, ensurethe power is capable of 12 volt DC @ minimum of 1 amp (ensure polarity is correct).Upon completion of the above steps the M105 Digital is now ready for use.The unit will already be in the receive mode and listening for incoming signals. To talk to a diver and/or another surface station, hold the band held microphone, depress the push-to-talk (PTT) switch located on the side of the hand held microphone and speak slowly. When you release the PTT button, the M105 Digital will return to the receive mode.You must remember that all divers are bearing noise underwater (i.e. bubble, Biological or man made noise). When you depress the PTT button located on the hand held micro- phone, a “beep” will be sent out to all transceivers. This tone should get the attention of the divers you want to talk to.Everyone hearing this tone should assume someone is going to talk and listen for the in coming message.Everyone should talk in a moderate voice and speak a little slower than normal. Divers should try to be in a inhalation cycle when listening to a voice message. This will help eliminate bubble noise while listening to messages. However , do not inhale slowly orhold your breath while surfacing.4.1| MaintenanceAlthough the M105 Digital is a rugged design it should be treated like any good quality electronic instrument. Avoid transportation in modes that would expose the unit to constant vibrations and knocking about. Ship the unit well packaged and DO NOT ship with the battery installed.After use, wipe the unit free of dirt, debris and/or water. Use a clean, soft cloth. Warm water with a small amount of nonabrasive soap is the recommended cleaning solution.The transducer should be kept clean and free of oils.The transducer itself can be cleaned with rubbing alcohol.The transducer assembly should be stored in a separate container if wet after a dive.Store the hand-held microphone in a dry area.The microphone is not water-proof and should be kept as dry as possible. Keep it free of water or from water spray. Mild soap solution and wiped dry is the preferred cleaning method. Inspect battery periodically to ensure it is in good order .When the M105 Digital is not being used, it is a good idea to keep the cover security fastened.Remember, when the transducer assembly is connected to the M105 Digital, the poweris ON if switch is ON too.12M105Digital w/battery level tester | M105D MARINER - rel. 1.35.1 | TransducerIt is important that the transducer be protected. It is designed using a material that can break if sharply hit or impacted. It is also important you do not hang the transducer in a position that is blocked or laying on the bottom. Inform all divers that if they go below a thermocline they inform everyone. If possible, lower the transducer to the same depth as the divers in the thermocline. It is extremely important to remember to pull the transducer up when moving a vessel.Many transducers have been lost when cut off by a propeller.5.2 | Hand-held MicrophoneMost all hand-held microphones are not waterproof. Keep them as dry as possible.5.3 | Placement of the M105DigitalThe M105 Digital should be placed where it can be easily beard. If working out of a boat, locate a place where you can secure the unit where boat action will not cause it to fall. Also, remember to dress the transducer cable in such a way that divers and/or topside personnel will not trip over it.5.4 | Talking & ListeningWhen talking to divers keep in mind they have a lot of things going on while underwater. It is best to get the divers attention before giving him-her a message. Also re- member to talk slowly and in one continuous sentence. Try not to make long sentences. It is always a good idea to have the divers repeat the message back so you know they clearly understood your message.Listening to divers is usually easier than divers listening to the topside tender. Again, repeat what you beard the divers say to ensure everyone is communicating accurately. Talking and listening while diving is something that takes practice and will improve every time a team works together.M105Digital w/battery level tester | M105D MARINER - rel. 1.313M105Digital w/battery level tester | M105D MARINER - rel. 1.3145.5| In the BeginningIf this is the first time you or anyone of your team is using communications, it is recommended the team get together to talk about the system. Plan alternative communications in the event something is not working. A pool session or a place where the team can practice in a controlled environment is the best preparation.It has been our experience that every dive using communications will make you a little better as a communication diver . With experience, you and your dive buddy will become use to verbal communications making it hard to dive without it.Accessories & Spare Parts>> Accessories M-105 Headset M-105 mixer for audio output External power cable for 12 volts >> Spare parts 6 volts rechargeable battery Charger 220/6 volts Charger 110/6 volts Microphone for M105Digital 26mm Antenna w/394” cable (rel.1.1)part #8859OR0065128594part #21038210372103585958608M105 Digital is warranted against defects in material and/or workmanship for a period of 6 (six) months from the time of purchase.

韩达5档手动变速箱说明书

韩达5档手动变速箱说明书

Drive in the highest gear that lets the engine run and acceleratesmoothly.This will give you the best fuel economy and effective emis-sions control.The following shift points are recommended:If you exceed the maximum speed for the gear you are in,the engine speed will enter into the tachometer’s red zone.If this occurs,you may feel the engine cut in and out.This is caused by a limiter in the engine’s computer controls.The engine will run normally when you reduce the RPM below the red zone.Before downshifting,make sure the engine will not go into the tachometer’s red zone.Shift up 1st to 2nd 2nd to 3rd 3rd to 4th 4th to 5thNormal acceleration 15mph (25km/h)25mph (40km/h)40mph (65km/h)50mph (80km/h)Your Honda’s transmission has five forward speeds,and is electronically controlled for smoother shifting.It also has a ‘‘lock-up’’torque converter for better fuel economy.You may feel what seems like another shift when the converter locks.5-speed Manual Transmission,Automatic TransmissionAutomatic TransmissionRecommended Shift Points Engine Speed Limiter222The ‘‘D’’indicator comes on for a few seconds when you turn the ignition switch to ON (II).If it flashes while driving (in any shift position),it indicates a possible problem in the transmission.Avoid rapid acceleration and have the trans-mission checked by an authorized Honda dealer as soon as possible.This indicator between the tacho-meter and speedometer shows which position the shift lever is in.Automatic TransmissionShift Lever Position Indicator223This position mechani-cally locks the e Park whenever you are turning off or starting the engine.To shift out of Park,you must press on the brake pedal and have your foot off the accelerator pedal.Press the release button on the side of the shift lever to move it.If you have done all of the above and still cannot move the lever out of Park,see Shift Lock Release on page .You must also press the release button to shift into Park.To avoid transmission damage,come to a complete stop before shifting into Park.The shift lever must be in Park before you can remove the key from the ignition switch.Use Neutral if you need to restart a stalled engine,or if it is necessary to stop briefly with the engine idling.Shift to Park posi-tion if you need to leave the car for any reason.Press on the brake pedal when you are moving the shift lever from Neutral to another e this position for your normal driving.The transmis-sion automatically selects a suitable gear (1through 5)for your speed and acceleration.You may notice the transmission shifting up at higher speeds when the engine is cold.This helps the engine warm up faster.226Automatic TransmissionPark (P)Neutral (N)Drive (D)224To shift to Second,press the release button on the side of the shift lever.This position locks the transmission in second gear.It does not downshift to first gear when you come to a stop.Secondgives you more power when climbing,and increased engine braking when going down steep e second gear when starting out on a slippery surface or in deep snow.It will help reduce wheelspin.To shift from Second to First,press the release button on the side of the shift lever.With the lever in this position,the transmission locks in First gear.By upshifting and downshifting through 1,2,D ,and D,you can operate this transmission much like a manual transmission without a clutch pedal.For faster acceleration when in D or D,you can get the transmission to automatically downshift by pushing the accelerator pedal to the floor.The transmission will shift down one or two gears,depending on your speed.This position is similar to D,except only the first threegears are selected instead of all e D when towing a trailer in hilly terrain,or to provide engine braking when going down a steep hill.D can also keep the transmission from cycling between third and fourth gears in stop-and-go driving.3333Second (2)First (1)Drive (D )Automatic Transmission3225This allows you to move the shift lever out of Park if the normal method of pushing on the brake pedal and pressing the release button does not work.Set the Parking brake.Remove the key from the ignition switch.If you exceed the maximum speed for the gear you are in,the engine speed will enter into the tachometer’s red zone.If this occurs,you may feel the engine cut in and out.This is caused by a limiter in the engine’s computer controls.The engine will run normally when you reduce the RPM below the red zone.Put a cloth on the edge of the Shift Lock Release slot cover next to the shift lever.Use a small flat-tipped screwdriver or finger nail file to remove the cover.Carefully pry off the edge of the cover.1.2. 3.Automatic TransmissionShift Lock ReleaseEngine Speed Limiter226If you need to use the Shift Lock Release,it means your car isdeveloping a problem.Have the car checked by your Honda dealer.Insert the key in the Shift Lock Release slot.4.Automatic Transmission227。

千元性能标杆 iQOO Z5

千元性能标杆 iQOO Z5

千元性能标杆iQOO Z5作者:***来源:《微型计算机》2021年第21期作为一款中端走量机型,iQOO Z系列的迭代速度不可谓不快,从今年3月发布Z3到9月发布的Z5,仅过了六个月的时间。

换代机型iQOO Z5无论是在外观还是在性能上都得到了一定程度的升级,并且还加入了UFS 3.1闪存、双扬声器和线性马达等更高配置,那么这款主打性价比的干元机到底实际表现如何呢,我们一起来看看。

棱镜幻彩加持千元也有好外观或许不少用户会对iQOO Z3的外观印象深刻,毕竟在2021年还使用“水滴屏”的设计始终让人觉得是前两年的产品。

不过iQOO Z5完全舍弃了水滴屏设计,改为居中挖孔屏,而这也是目前中端机型的主流设计。

屏幕方面,iQOO Z5采用了一块6.67英寸LCD屏幕,最高支持120Hz刷新率和240Hz触控采样率,拥有1500:1的对比度和最高480nits亮度,并且支持HDR10和JBM高亮模式。

iQOO Z5的背面设计也为这台干元机加分不少,一般用户普遍认为千元机在外观上要有多凑合就有多凑合,但我们手中的这台“造梦空间”配色的iQOO Z5却给予了我们精致的感觉。

棱镜幻彩的背壳工艺和有韵律感的CD纹理,让iQOO Z5的外观别具一格,在不同角度下还会反射出不同的色彩。

值得一提的是,虽然看上去“造梦空间”版iQOO Z5在背壳上有着类似行李箱的表面纹理,但摸上去却是纯平的,不易沾染指纹的磨砂手感搭配摄像头处的亮面玻璃,总体看上去比较精致。

细节上,iQOO Z5的机身厚度为8.49mm,重量为193g,配合后盖左右的双曲面设计可以带来不错手感。

iQOO Z5选择了侧面指纹识别方案,右侧的电源键能够兼顾指纹识别,轻按点亮屏幕的同时即可解锁,实测解锁速度较快。

另外iQOOZ5还保留了3.5mm耳机孔,这在当下来说比较难得。

骁龙778G铁三角日常娱乐无压力千元机的性能表现到底如何,iQOO Z5或许就是标杆。

求职细节多做求职细节多做5%5%5%,就能得到,就能得到,就能得到200%200%200%的回报的回报如果你现在正面临着求职,那么除了做好简历等重要的求职准备,还要注意一些小的细节。

这些细节虽然细,但作用却不小。

很多时候,你多付出5%,收获的却是200%。

◎培养自己穿着打扮的品位虽然没有任何一个招聘启事上会说“此职位要求相貌端庄”,但是,100%的企业都会把外表作为第一招聘条件,就算你从事的是幕后工作,比如程序员,外表也一样是审核的标准。

原因很简单:一,你代表的是企业形象;二,懂得装扮自己的人比打扮灰暗的人自信得多;三,打扮隆重自然代表着该应聘者对职位的热忱度。

请注意,我在这里强调的是装扮的品位,而不是说你要成为帅哥美女。

先天不足,后天可补,你的穿着打扮是否有品位,能否给人以信任感,是每个求职者必须揽镜自照“扪脸自问”的问题。

还要强调的是,着装打扮不只是对女性的要求,男性同样要重视这个问题。

◎要为企业定制简历先来举一个我所遇到的真实案例。

有一次,我公司招聘营销人员,在堆积如山的简历中,有一份简历引起了我们的注意。

求职者在简历后面附了专门针对我公司产品的调查报告,为了这份报告,这位求职者在投简历前,做了连续一周的市场调查。

最后,在长达几页纸的调查报告后面,求职者标注了一句话:“如果想知道详细情况,请与我联系!”我们自然联系了他,首先他的敬业态度已打动了我们;此外,他的调查也很有意思,这也是企业最关心的问题。

每一个求职者在制作简历时都应该像案例中这位求职者那样用心。

你所发出去的每一份简历,都要根据所申请的职位度身制作。

在每一份简历上,都应该出现应聘单位的名字或者产品。

即使你在发送简历之前草草地上一下招聘单位的网站,把人家的企业标语拷贝到自己简历的页眉上,你的成功概率也会立刻增加。

如果你能在简历的页脚简单描述自己对其产品和服务的认知,你的简历将再次获得加分。

即使是在人潮汹涌的招聘会现场,你也可以快速浏览一下招聘企业的宣传板,挑选一两句能够和你的简历结合的信息,手写在简历的页眉或页脚。

比如,如果你看到“卓越公司”的招聘要求是“打字速度60字/分钟”,你不妨在页眉上手写一句“本人打字是卓越要求的两倍:120字/分钟,希望有机会为您打字!”当然,在找工作的过程中,次次修改简历会使你感觉无比的辛苦。

尤其是经历了无数次简历没回音,笔试被废,面试被拒之后,你可能会非常气馁。

但是,过程永远没有结果重要,如果你想提高自己简历的成功几率,就必须次次修改简历。

◎主动向你的人脉网通报情况你要把自己的求职情况每周向自己的“人脉网”做一个汇报。

能够有资格做你“人脉”的人,往往是非常繁忙的专业人士,如果你不找他,他很难有时间想起你的事情来。

在E-mail 里,别忘了叮嘱一句,告诉人家绝对不需要特意回复自己的邮件。

你大可不必担心自己会打扰你的“人脉”大哥、大姐或大叔、大婶,年长的人们在后辈的“挣扎”中会感受到自己的成功与快乐(并非心理变态),并且乐于在可能的情况下施以援手,以更深刻地体会到快乐。

不要怀疑这种方法是否有效,去做吧。

◎找好亲密战友求职道路上的亲密战友,有两类人。

一类是你所积累的人脉资源,还有一类就是和你一起并肩战斗的也在找工作的人。

人脉资源就是“关系网”,总是在成功元素排行榜上名列前茅。

前面说过,最有效的“求职途径”就是内部推荐。

内部推荐绝对不是暗箱操作的黑色秘密,而是招聘经常采用的一种手段。

很多大公司为鼓励员工推荐优秀人才来就职,都设立明文的物质激励条款,比方说耐克公司对介绍自己朋友来任职的员工奖励一双耐克鞋,新东方对优秀教师的推荐人给予现金奖励,等等。

大一的时候,如果你和大四的师兄、师姐以及研究生的大师哥、大师姐建立友谊,他们就是你大四就业时的宝贵资源。

大学男生一律把交友的目光锁定在“小师妹”身上,往往毫不理会高自己两级的师姐。

追求师妹是可以理解的,但是和师姐建立同志式的友谊或许对你更有帮助。

第二类亲密战友,是和你一起找工作的人,你可以和他们组成求职小组,你会得到很多好处:比如分头查找职位资讯;分头研究招聘单位与岗位,资源共享;可以互相扮演面试官,进行模拟面试,等等。

◎备好五个行头求职必备的五个行头是:一个“健康专业”的E-mail地址,一个稳定的几年不变的电话号码,一身求职套装,一只公文包,一个求职笔记本。

健康的E-mail地址,不应该是什么Iloveyou、KITTYCAT等个性化太强、男欢女爱或卡通味道太浓的E-mail.如果你在找工作,赶紧注册一个规规矩矩的E-mail地址,然后不妨用上一辈子。

一个稳定的几年不变的手机号码非常重要,说不定哪一天,你几年前失之交臂的企业会再次给你打电话。

事先准备好求职套装是极其必要的,这会免去你面试前的手忙脚乱。

一只公文包非常重要。

很多求职者去面试的时候挎着一个很休闲的包,让面试官一看就不专业。

准备一个求职笔记本,把自己的每一个求职步骤记录其中,当你记满半本的时候,好的offer自然就来了。

很多的求职者,由于海投简历实在太多,根本就不记得在哪个单位应聘了什么职位,自然就会与机会一个一个失之交臂。

5%比别人早准备比别人早准备5%◎尽早开始,时刻准备求职不是临时抱佛脚的事情,不是看了本书明天就能够顺利过关的。

求职者应尽早做好规划,并且有计划地培养自己的能力。

求职准备绝对不是仅仅背诵一些干巴巴的答案,它包括方方面面能力和信息的准备:对某个行业的专业知识,对某个具体职业的专业知识,而这些知识不是临时抱佛脚可以得来的;语言表达能力,你可能被要求阐述自己并不熟悉的话题,而口才不是一天就能练好的;梳妆打扮的能力,因为印象分至少占三成权重,而品位不是一天就能积累的;应变能力、沟通能力、领导能力……◎不断总结经验求职是一个整理自己的思路,认识自己的过程。

在求职过程中,特别是与面试官面对面时,面试官会提出很多自己以前不曾考虑过的问题,这些问题这样或那样地反映着自己某方面的特质。

通过求职,你会很惊讶地发现,原来自己还不是很清楚自己。

很多求职者可能会面试很多次才能获得满意的OFFER(录取通知)。

一次面试就是一次成长。

吃一堑,长一智,面试之后要懂得总结。

求职不顺利的经验其实也是相当宝贵的,它可以真实地反映出求职者身上存在的种种问题。

每次面试之后思考下面几个问题:这次面试中我犯了哪些错误?这次面试中我哪些地方表现不错?上次面试中出现的错误这次是否再次重犯?和我同时面试的应聘者有哪些地方值得学习?他们的哪些失误我可能也会犯?如何避免?除了从自身找经验,求职者还应当奉行拿来主义,通过网络或者上门请教等途径,看一看别人是怎么参加面试的。

总结别人的面试经验,可以让自己少走弯路,少碰壁。

求职者中有一类人被称作“拒无霸”,简单地说,就是那些不断求职,却永远被拒绝的人。

成为“拒无霸”的求职者,有的是才能不济,有的是因外貌、身高、性别等客观原因遭拒。

这虽然有用人单位的问题,但求职者自身不懂得从中反思自身问题,也是一个重要原因。

5%比别人主动5%比别人主动◎投出简历后主询问情况投出简历之后,如果只是静候佳音、听之任之,那么你很可能会丧失潜在的机会。

正确的做法是,投出简历后,或在用人单位公告的投递简历截止日期之日起一周左右后,与公司人事部门的工作人员联系,询问你是否在笔试/面试名单之列。

如果不在,你也要努力争取。

值得注意的是,在与应聘方联系之前,你要事先估计自己哪方面可能是劣势,然后想好如何说服对方。

如果他们还没有整理筛选完简历,那么询问他们何时可以给出答复,到时候你再联系。

争取这个环节很重要,因为筛选简历并不像评判数学试卷一样有一个标准答案,非对即错。

即使筛选简历的工作人员认为你的简历暴露了你某方面的不足,但你对他们公司的热诚却极有可能弥补这方面的不足。

如果你得到了多家公司的面试通知,其中包括你不太感兴趣的公司,这时候也不要拒绝。

最好的做法是,你把他们的面试安排在你重视公司的面试之前,一方面多给自己一个机会,另一方面就拿它来练习你的面试技巧,这对提高你的面试水平、克服紧张心理无疑有很大的帮助。

◎面试后,礼貌地查询结果面试完毕,最令人挂心的就是面试结果。

虽然例行的回答是两周内等通知,其实研究出结果一般不需要那么长时间。

面试过后一个星期没有回复是很正常的,求职者在这段时间内一定要耐心等待面试结果的反馈信息,不要过早打听面试结果。

此时切不可到处打听消息,更不要托人“刺探”。

如果面试两周后或主考官许诺的时间到来时,仍未收到通知,你可写信、发E-mail给主持面试的人员询问面试结果(为了有这个机会,面试告辞时别忘了向面试官要一张名片),一是提醒一下招聘方,表示自己对这个公司很感兴趣;二是在考官难以做出判断时,你的信件可能为自己增加入选的机会。

即使未被录用,也最好能与主考官保持联系,这也是建立职业关系网的一个重要组成部分,很可能在今后你仍有机会进入你所心仪的单位。

在此,我不太建议打电话询问,一来可能干扰对方的工作,二来可能让对方觉得不方便回答而陷入尴尬境地,此外很容易出现措辞不当的失误,而且显得过于心急。

回打的咨询电话中,措辞很重要。

多数求职者会问:“面试结果出来了吗?”“人员定了吗?”这些问题往往要最终录用通知下达后,人事专员才方便回答。

建议求职者换种方式询问,你可以说:“我是竞聘××职位的×××,请问我被录用的希望大吗?”或者“我是竞聘××职位的×××,请问我面试的综合评价是不是没有靠前几位?”这样,接电话的人事专员不免可以透露一点,聪明的你自然能够听得出来。

◎对心仪的职位要主动争取作为求职者,需要有一种敢于“主动出击”“积极争取”的素质。

我曾遇到过这样一位求职者,他在通过了简历筛选后,希望到销售部门去工作。

由于这个求职者是个新手,我感觉他做研发也非常适合,于是建议他去研发部门。

后来几天,这个求职者天天“缠”着我,希望进入心仪的部门。

我发现,他的这种锲而不舍的精神正是销售人员不可或缺的,于是最终推荐他去了销售部门。

◎面试后主动写一封感谢信面试结束后写一封用心的感谢信,对那些已经进入决赛圈的人是举足轻重的。

在我的经历中,就有人因为写了一封有内容的感谢信而得到了工作。

道理很简单,假如有几个旗鼓相当的人一起进入决赛圈,但只有一个人能够得到机会,这时假如你写了一封感谢信,就等于比别人多了一次向招聘单位推销自己的机会。

假如你的感谢信言辞生动恳切,强调了你的技能和工作经验,表示你想得到这份工作并且很适合它,那么这样一封信可能起到一锺定音的作用。

感谢信不会有任何负面影响,而且还可能有起死回生的作用。

有这样一个案例:一位面试感觉不错的求职者刚送出了一封感谢信,却得知自己落选了。

他马上又送出了第二封信,信中表达了未被选中的遗憾,同时表示自己对这个公司的向往,希望公司在今后出现工作空缺时考虑自己。
