Lewmar products are world renowned for their quality, technical innovation and proven performance. With a Lewmar product you will be provided with many years of outstanding service.Product supportLewmar products are supported by a worldwide network of distributors and Authorised Service Representatives. If you encounter any difficulties with this product, please contact your national distributor, or your local Lewmar dealer. Details are available at: CE ApprovalsFor CE approval certificates contact Lewmar.Important information about this manualThroughout this manual, you will see safety and product damage warnings. You must follow these warnings carefully to avoid possible injury or damage.The type of warnings, what they look like, and how they are used in this manual are explained as follows:.2Lewmar VX1 Vertical Windlass 65100045.Iss 11 32. Safety NoticeIMPORTANT: Read these notes before continuing.2.1 Windlass generalClassification Societies and Lewmar require that a vessel at anchor must have its chain/rode held by a chain stopper or equivalent strong point at all timesAt all times it is the responsibility of the boat operator to ensure that the anchor and rode are properly stowed for the prevailing sea conditions. This is particularly important with high-speed powerboats, because an anchor accidentally deploying while under way can cause considerable damage. An anchor windlass is mounted in the most exposed position on a vessel and is thus subject to severe atmospheric attack resulting in a possibility of corrosion in excess of that experienced with most other items of deck equipment. As the windlass may only be used infrequently, the risk of corrosion is further increased. It is essential that the windlass is regularly examined, operated and given any necessary maintenance.Please ensure that you thoroughly understand the operation and safety requirements of the windlass before commencing the installation. Only persons who are completely familiar with the controls and those who have been fully made aware of the correct use of the windlass should be allowed to use it. If there is any doubt of how to install or operate this unit please seek advice from a suitably qualified engineer.• Windlasses used incorrectly could cause harm to equipment or crew.• Windlasses should be used with care and treated with respect.• Boating, like many other activities can be hazardous. Even the correct selection, maintenance and use of proper equipment cannot eliminate the potential for danger, serious injury or death.• Lewmar windlasses are designed and supplied for anchor control in marine applications and are not to be used in conjunction with any other use.• Keep limbs, fingers, clothing and hair clear of windlass, rode and anchor during operation. Severe bodily harm could result.• Ensure there are no swimmers or divers nearby when dropping anchor.• Windlasses must not be used as the sole means of securing the anchor to the bow fitting especially under storm conditions. Anchors should be independently secured to prevent accidental release.• Classification Societies require that a vessel lying at anchor must have its anchor rope/chain secured to a chain stopper or other suitable independent strong point.• A windlass should never be used as a mooring bollard, the anchor rode MUST be secured to a mooring cleat, chain stopper or other designated strong point. Using the windlass to secure the rode will damage the windlass.• Do not use windlass for ANY purpose other than deployment and recovery of anchor.• The circuit breaker in this product must never be deactivated or otherwise bypassed, it is intended to protect the motor and cables from overheating and damage.• Always switch off this windlass at the circuit breaker/isolator when not in use.• It is the unavoidable responsibility of the owner, master or other responsible party to assess the risk of any operation on the vessel.• Windlass must not be operated whilst under the influence of alcohol or drugs.2.2 Fitting• This equipment must be installed and operated in accordance with the instructions contained in this manual. Failure to do so could result in poor product performance, personal injury and/or damage to your boat.• Consult the boat manufacturer if you have any doubt about the strength or suitability of the mounting location.2.3 Electrical• Make sure that the boat’s battery power supply has been switched off before starting the installation.• This product requires installation by a suitably qualified electrical engineer.43. Installation3.3 Gypsy SuitabilityGypsies fitted to the VX range of windlasses are ideally suited to handling our factory made Rope/Chain combination rodes, which consist of rope spliced to a chain tail. See Specifications section for details.Ropes used must be windlass grade, medium lay nylon. Ropes from different manufacturers have wide variations in stretch and consistency in diameter. Therefore, rope and chain from other manufacturers may require some experimentation to determine the optimum size.Should you have difficulty in matching a gypsy to your chain please consult your local agent or our international network of distributors.3.4 Above deck preparationIMPORTANT - Plan location carefully and allow for the following:3.2 AccessoriesUse only genuine Lewmar parts and accessories to ensure top performance and eliminate the risk of voiding your warranty. For replacement parts, please visit your dealer or 3.1 Basic requirementsEach installation requires the following tools:Wiring Installation• Crimping Pliers / Wire Stripper• Suitable electrical cable and crimp terminalsWindlass InstallationAn appropriate marine sealant and the following:1. Make an accurate drilling template using the product dimensions from the dimension template and decide upon a position for it with reference to the vessel’s bow roller and the chain locker below and the rotation of manual operating handle. If possible, select a flat area of deck.VX 1• 10 mm (3/8”) Drill • 14 mm (9/16”) Drill • 18 mm (45⁄ 64”) Drill• 40 mm (1 37⁄ 64”) Hole Saw • 67 mm (2 1/4”)Hole SawVX 2/3• 10 mm (3/8”) Drill • 14 mm (9/16”) Drill • 18 mm (45⁄ 64”) Drill• 46 mm (1 13⁄ 16”) Hole Saw • 62 mm (2 7⁄ 16”)Hole SawVX 1L• 10 mm (3/8”) Drill • 15 mm (19/32”) Drill• 67 mm (2 1/4”) Hole Saw • 100 mm (3 15/16”)Hole SawLewmar VX1 Vertical Windlass 65100045.Iss 11 5Notes• if in doubt about the suitable construction of the pad consult a qualified marine engineer.• Decks that are thin, or of foam or balsa laminate construction, will require reinforcement in order to the windlass is in use2. correct minor misalignment.3.5 Deck thicknessThe deck is an integral component of the windlass it has to secure the windlass and be strong enough to cope with the high torque stresses involved in recovering the anchor.• Lewmar recommends a minimum deck thickness of 40mm (11/2”).63.6 Below deck preparationIMPORTANT:The positioning of the windlass must be checked prior to cutting for deck/hull and bulkhead clearance.1.The motor/gearbox is bolted via the through deck mounting bolts.NOTE: Do not position motor/gearbox below rode/chain pipe fall area.2. There must be sufficient vertical fall for the chain or rope when hauling in.3.7 Above deck fitting2. Using your template and after you have checked allthe above and below deck requirements cut thefollowing holes.VX1Using a 10mm (3/8”) diameter drill, make the 4 holes forthe mounting studs, 14mm (9/16”) and 18mm (45/64”) forthe sensors. With a 40mm (1 37/64”) and 67mm (2 1/4”)diameter hole saw, make two holes for the mainshaftand rode to pass through.VX2/3Using a 10mm (3/8”) diameter drill, make the 3 holes forthe mounting studs, 14mm (9/16”) and 18mm (45/64”) forthe sensors. With a 46mm (1 13/16”) and 67mm (2 1/4”)diameter hole saw, make two holes for the main unit /Motor gearbox and rode to pass through.1. Lead from the roller should be fed horizontally backto the top of the gypsy and along its centre linewithin ±5˚.8NOTE: Position the motor/gearbox away from the rope/chain pipe fall.2. Check the motor/gearbox and windlass mounting surfaces are parallel.• VX 1-3 - Assemble the washer then the M8 nut, secure with Loctite® threadlock to 21Nm torque.NOTE: If using silicone or other rubbery type sealant, it is advisable to allow curing of the sealant before final tightening of the mounting nuts.5. Place the base mat in position on the deck.Optionally, apply a suitable sealant to the base of the windlass, any mounting pad or around the studs.NOTE: If using silicone or other rubbery type sealant, it is advisable to allow curing of the sealant before final tightening of the mounting nuts.6. Lightly coat the shaft with grease and ensure the drive key is in place before assembly to motor/gearbox.Non-aplicable for VX1L3.8 Under deck fittingLewmar VX1 Vertical Windlass 65100045.Iss 1194. Electrical wiring4.1 Electric cable selectionInstallation of this product should meet the regulations and standards or codes of practice relevant to the craft to which it is being fitted. As a minimum the installer should conform ISO 10133.Lewmar recommends the installer use cable with insulation rated at 90°C or higher.Length = Length of cable from battery ‘+’ terminal and back to battery ‘-’ terminal including breaker and switch gear if fittedCable size guide given is for guidance only.It is the responsibility of the installer to confirm the capacity and voltage drop for the installation. If in any doubt,contact your local marine electrician.10Lewmar VX1 Vertical Windlass 65100045.Iss 11 11Plan the installation to suit the controls and give the operator a full view of the windlass. The wiring system should be of the fully insulated type, which avoids possible electrolytic corrosion problems. We recommend the use of type III stranded, tinned copper wire with copper crimp terminals. Most modern installations are negative return (negative ground) but polarity should be checked.Overload protection, in the form of the circuit breaker/fuse supplied, must be built into the windlass wiring circuit.Circuit breaker supplied: 50A (Part No 68000348) 70A (Part No 68000240) 90A (Part No 68000349) 110A (Part No 68000350)NOTE: The circuit breaker should be positioned close to the battery in a dry, readily accessible place.The breaker must be manually reset should an overload occur that causes it to trip to the off position. If you are not sure you understand these guidelines, seek professional help. Ensure that the installation complies with USCG, ABYC, NMMA or other local regulations.4.2 Wiring4.3 Control switch installationThe unit is supplied with• Guarded rocker switch (product ref 68000593)• Contactor VX1/VX1L (12V- 68000939)• VX2/3 (12V- 68000937) / VX2/3 (24V- 68000938)Follow the wiring diagramsNOTE: Optional electric footswitches and remote handheld control available.Visit for more information.Contactor box used in some installation refer to wiring diagram § 4.4 - 4.8Optional wireless remote also available see table below for models and references.NOTE: In a multi station installation all switches must be wired in a parallel circuit.‣When wiring Lewmar electric motor into the ship’s electrical system the following caution must be taken. ‣When tightening the front nut hold the back nut with a separate wrench to make sure the back nut does not turn.

Trouble shooting9.1 Electric windlass1. Anchor rode pays out independently while windlass is not in use.This problem is a result of not securing the anchor rode combined with the gypsy drive cap being slack. Tighten the gypsy drive cap using the winch handle and always secure the anchor rode independently of the windlass when not in use.2. Failure to operate or sluggish operation.• T he majority of these problems are electrical in nature. It is essential that the proper voltage be maintained. The proper voltage on a 12 Volt system is 13.5 Volts (24 Volt system is 26.5 Volts), constant low voltage will damage motor.• E nsure electrical cable size is large enough to handle the current draw and keep voltage drop within acceptable limits.• Check control switches, connections, battery condition, isolator switch, fuse and motor for operation failure.34Lewmar VX1 Vertical Windlass 65100045.Iss 11 3510.

WES系统 EWF和 FBWF
FBWF(File Based Write Filter)是微软在Windows XP Embedded SP2 Feature Pack 2007及以后版本中推出的最新写保护技术。
在FBWF写保护功能开启时,所有的写入操作都被重定向到内存上的一个区域中,这个内存区域称之为覆盖层(overlay),这点同EWF(Enhanced Write Filter)中的覆盖层的概念相同,不同的是FBWF的覆盖层只能支持内存方式,而EWF则能支持内存和磁盘两种方式。
本文将介绍什么是FBWF及其功能、FBWF详细配置、FBWF 控制台命令、FBWF Apis、FBWF同EWF的区别、FBWF的优缺点等内容。
FBWF介绍什么是FBWF: FBWF(File Based Write Filter)是微软在Windows XP Embedded SP2 Feature Pack 2007及以后版本中推出的最新写保护技术,FBWF能够将处于保护状态的卷的所有写入操作重新定向到一块内存区域,这块内存区域被称作覆盖层。
覆盖层类似于存储介质的一个投影,对存储介质做的任何写操作都将映射到覆盖层中,而这种操作对于用户而言是透明的,即我们看到的最终内容则是存储介质和覆盖层的叠加(见FBWF复合视图)。
另外我们能够对覆盖层中的数据进行操作,比如提交(Commit)、恢复(Restore)、......等。
FBWF工作过程如下图所示:FBWF Overview图FBWF复合视图增强的写入过滤器(EWF)是另外一个由Windows XP Embedded提供的写入过滤器,它通过截取对扇区级别的调用来完成写入过滤功能。
保护扇区级别的功能让EWF拥有了控制整个文件系统的能力,并通过对扇区的保护达到保护文件系统的目的。
然而,EWF盲目地过滤所有对扇区的读写操作,不能直接对文件进行保护。
由于FBWF正是针对文件级别设计的,它能够智能地针对文件、文件夹或者任何文件系统数据结构进行过滤,有效地达到了保护文件系统的目的。

It also achieves a constant slew rate, bandwidth and settling time over its entire specified temperature range. The AD826 (Figure 35) consists of a degenerated NPN differen-tial pair driving matched PNPs in a folded-cascode gain stage. The output buffer stage employs emitter followers in a class AB amplifier which delivers the necessary current to the load while maintaining low levels of distortion.–INNULL 1NULL 8S–VSFigure 35. Simplified SchematicThe capacitor, C F, in the output stage mitigates the effect of capacitive loads. With low capacitive loads, the gain from the compensation node to the output is very close to unity. In this case, C F is bootstrapped and does not contribute to the overall compensation capacitance of the device. As the capacitive load is increased, a pole is formed with the output impedance of the output stage. This reduces the gain, and therefore, C F is incompletely bootstrapped. Effectively, some fraction of C F contributes to the overall compensation capacitance, reducing the unity gain bandwidth. As the load capacitance is further increased, the bandwidth continues to fall, maintaining the stability of the amplifier.INPUT CONSIDERATIONSAn input protection resistor (R IN in Figure 25) is required in circuits where the input to the AD826 will be subjected to transient or continuous overload voltages exceeding the ±6 V maximum differential limit. This resistor provides protection for the input transistors by limiting their maximum base current. For high performance circuits, it is recommended that a “bal-ancing” resistor be used to reduce the offset errors caused by bias current flowing through the input and feedback resistors. The balancing resistor equals the parallel combination of R IN and R F and thus provides a matched impedance at each input terminal. The offset voltage error will then be reduced by more than an order of magnitude.APPLYING THE AD826The AD826 is a breakthrough dual amp that delivers precision and speed at low cost with low power consumption. The AD826 offers excellent static and dynamic matching characteristics, combined with the ability to drive heavy resistive and capacitive loads.As with all high frequency circuits, care should be taken to main-tain overall device performance as well as their matching. The following items are presented as general design considerations. Circuit Board LayoutInput and output runs should be laid out so as to physically isolate them from remaining runs. In addition, the feedback resistor of each amplifier should be placed away from the feedback resistor of the other amplifier, since this greatly reduces inter-amp coupling.Choosing Feedback and Gain ResistorsIn order to prevent the stray capacitance present at each amplifier’s summing junction from limiting its performance, the feedback resistors should be ≤ 1 kΩ. Since the summing junction capaci-tance may cause peaking, a small capacitor (1 pF–5pF) may be paralleled with R F to neutralize this effect. Finally, sockets should be avoided, because of their tendency to increase interlead capacitance.Power Supply BypassingProper power supply decoupling is critical to preserve the integrity of high frequency signals. In carefully laid out designs, decoupling capacitors should be placed in close proximity to the supply pins, while their lead lengths should be kept to a mini-mum. These measures greatly reduce undesired inductive effects on the amplifier’s response.Though two 0.1µF capacitors will typically be effective in decoupling the supplies, several capacitors of different values can be paralleled to cover a wider frequency range.AD826؎SINGLE SUPPLY OPERATIONAn exciting feature of the AD826 is its ability to perform well in a single supply configuration (see Figure 37). The AD826 is ideally suited for applications that require low power dissipation and high output current and those which need to drive large capacitive loads, such as high speed buffering and instrumentation. Referring to Figure 36, careful consideration should be given to the proper selection of component values. The choices for this particular circuit are: (R1 + R3)ʈR2 combine with C1 to form a low frequency corner of approximately 30 Hz.OUT0.1VFigure 36. Single Supply Amplifier Configuration R3 and C2 reduce the effect of the power supply changes on the output by low-pass filtering with a corner at12πR3C2.The values for R L and C L were chosen to demonstrate the AD826’s exceptional output drive capability. In this configura-tion, the output is centered around 2.5 V. In order to eliminate the static dc current associated with this level, C3 was inserted in series with R L.Figure 37.Single Supply Pulse Response, G = +1,R L = 150Ω, C L = 200 pFPARALLEL AMPS PROVIDE 100 mA TO LOADBy taking advantage of the superior matching characteristics ofthe AD826, enhanced performance can easily be achieved byemploying the circuit in Figure 38. Here, two identical cells areparalleled to obtain even higher load driving capability than thatof a single amplifier (100 mA min guaranteed). R1 and R2 areincluded to limit current flow between amplifier outputs thatwould arise in the presence of any residual mismatch.LFigure 38.Parallel Amp ConfigurationAD826SINGLE-ENDED TO DIFFERENTIAL LINE DRIVEROutstanding CMRR (> 80 dB @ 5 MHz), high bandwidth, wide supply voltage range, and the ability to drive heavy loads, make the AD826 an ideal choice for many line driving applications.In this application, the AD830 high speed video difference amp serves as the differential line receiver on the end of a back terminated, 50 ft., twisted-pair transmission line (see Figure 40).The overall system is configured in a gain of +1 and has a –3 dB bandwidth of 14 MHz. Figure 39 is the pulse response with a 2 V p-p, 1 MHz signal input.Figure 39.Pulse ResponseFigure 40.Differential Line DriverLOW DISTORTION LINE DRIVERThe AD826 can quickly be turned into a powerful, low distor-tion line driver (see Figure 41). In this arrangement the AD826can comfortably drive a 75Ω back-terminated cable, with a 5MHz, 2 V p-p input; all of this while achieving the harmonic distortion performance outlined in the following table.Configuration 2nd Harmonic 1.No Load –78.5 dBm 2.150 Ω R L Only –63.8 dBm 3.150Ω R L 7.5Ω R C–70.4 dBmIn this application one half of the AD826 operates at a gain of 2.1 and supplies the current to the load, while the other pro-vides the overall system gain of 2. This is important for two reasons: the first is to keep the bandwidth of both amplifiers the same, and the second is to preserve the AD826’s ability to oper-ate from low supply voltages. R C varies with the load and must be chosen to satisfy the following equation:R C = MR Lwhere M is defined by [(M+ 1) G S = G D ] and G D = Driver ’s Gain,Figure 41.Low Distortion AmplifierAD826HIGH PERFORMANCE ADC BUFFERFigure 42 is a schematic of a 12-bit high speed analog-to-digital converter. The AD826 dual op amp takes a single ended input and drives the AD872 A/D converter differentially, thus reduc-ing 2nd harmonic distortion. Figure 43 is a FFT of a 1MHz input, sampled at 10 MHz with a THD of –78 dB. The AD826can be used to amplify low level signals so that the entire range of the converter is used. The ability of the AD826 to perform on a ±5 volt supply or even with a single 5 volts combined with its rapid settling time and ability to deliver high current to compli-cated loads make it a very good flash A/D converter buffer as well as a very useful general purpose building block.V Figure 42.A Differential Input Buffer for High Bandwidth ADCsFigure 43.FFT, Buffered A/D ConverterAD826OUTLINE DIMENSIONSDimensions shown in inches and (mm).8-Lead Plastic Mini-DIP (N) Package8-Lead SO (R) Package45؇All brand or product names mentioned are trademarks or registered trademarks of their respective holders.C 1807a –0–6/00 (r e v .

range(-T model)CertificationsIntroductionNPort®5400device servers provide many useful features for serial-to-Ethernet applications,including an independent operation mode for each serial port,user-friendly LCD panel for easy installation,dual DC power inputs,and adjustable termination and pull high/low resistors.Network Readiness for up to4Serial DevicesNPort®5400device servers can conveniently and transparently connect up to four serial devices to an Ethernet network,allowing you to network your existing serial devices with only basic configuration.Data transmission between the serial and Ethernet interfaces is bidirectional.By using NPort®device servers,you not only protect your current hardware investment,but also allow for future network expansion.You can both centralize the management of your serial devices and distribute management hosts over the network.Independent Operation Mode for Each Serial PortNPort®5400device servers can be used to connect different devices for remote data polling or event handling over a TCP/IP network.Each serial port on the NPort®5400operates independently to provide maximum versatility.For example,port1can operate in Driver mode,port2in TCP Server mode,and ports3and4in TCP Client mode.User-friendly LCD Panel for Easy InstallationAn LCD panel is built into the NPort®5400’s top panel,with fourbuttons for data input,configuration,and operation mode selection.The LCD panel displays the server name,serial number,and IPaddress,and it can be used to enter or modify parameters such as IPaddress,netmask,and gateway.(The LCD panel is not available onwide-temperature models.)Dual DC Power InputsNPort®5400device servers support dual power sources by providingboth a DC terminal block input and a DC power jack input.Providingtwo types of power inputs gives users greater flexibility for use withdifferent applications.Adjustable Termination and Pull High/Low ResistorsThe NPort5400Series provides adjustable termination and pull high/low resistors for RS-485applications.In some critical environments,termination resistors may be needed to prevent the reflection of serialsignals,and the pull high/low resistors may need adjusting tomaintain the integrity of the electrical signal.Since no set of resistorvalues is universally compatible with all environments,the NPort®5400has four sets of DIP switches on the bottom panel to set thetermination and pull high/low resistor values.SpecificationsEthernet Interface10/100BaseT(X)Ports(RJ45connector)1Magnetic Isolation Protection

网站推广()提供什么是网站流量数据的统计和分析呢?他有什么用?给大家分解一下,通常说网站的流量就是说网站的访问量,通俗一点就是用户浏览页面的数量,常用的统计指标包括网站的独立用户数量、用户在网站的平均停留时间等。
那网站的流量统计分析是指在获得网站访问的基本数据的情况下,对有关数据进行统计、分析,为什么要统计,主要是为了用户在访问自己网站时候主要存在的问题和用户主要关注什么比较多一点等等,这样及时的更新用户喜欢的内容,对网站有很好的效果。
分析网站的工具我给大家建议还是用51啦统计比较好,当然现在也出了一个叫维度的统计工具有时间大家可以去看下我也装了一个,个人感觉不是很好用维度需要邀请码,你们想要的可以和我联系我可以给大家。
还有一个统计比较好的就是雅虎统计了推荐使用,大家只要注册玩了以后就会给你网站一段代码,你只要把这段代码放在首页中就可以每天查自己的统计了。
说到这我就顺便说下w3c标准,w3c是一个检测网站页面错误的一个标准,w3c也直接影响着PR,大家可以在百度搜w3c查询第一个是个英文的网站,进去后输自己的网址下面就会出现网站错误的位置,大家要及时处理一下,如果你错误处理完了以后w3c 也会给一段代码大家可以拿出来秀下,嘿嘿。
回到主题大家装完了51啦和雅虎统计可以看自己网页下面的图标就直接可以进去分析网站了。
现在统计完了我再主要说下怎么样分析自己的网站,我说下51啦的统计。
建业的站是网络营销专家,进去之后有今日详情、昨日详情、前日详情、本周一等等,这样大家就可以详细的分析每天的统计了。
我主要说下今日统计,大家进了今日详情后第一个就是访问量,这是一个全面的统计后面一个是搜索引擎,这就可以看到今天是哪个搜索引擎进自己的站了我的基本都是从百度和谷歌来的这样方便大家主要针对哪个搜索引擎,后面就是关键词这个可以看到主要是什么词才进到自己的站的,我的有几个都是网络营销入门和营销入门这样可以让大家知道主要优化哪个词还有就是来路,这样可以看到是自己输的网址还是从搜索引擎来的,还有就是回头客和浏览深度这个可以看到用户是第几次来的来具体分析。
威派格 数据元素
威派格数据元素威派格(Vega)是一种用于描述金融衍生品的数据元素,它是金融衍生品定价和风险管理中必不可少的工具。
威派格数据元素由一系列指标组成,用于描述衍生品的特征、风险和定价模型。
本文将详细介绍威派格数据元素的相关内容。
一、期权数据元素1. 标的资产:期权合约所涉及的标的资产,可以是股票、商品、外汇等。
2. 期权类型:期权合约的类型,可以是认购期权或认沽期权。
3. 行权价格:期权合约约定的标的资产买卖价格。
4. 到期时间:期权合约的到期日期或到期时间。
5. 波动率:标的资产价格的波动程度。
6. 无风险利率:期权合约的到期时间内可获得的无风险利率。
7. 股息率:标的资产支付的股息。
二、期权定价模型数据元素1. 希腊字母:用于度量期权合约价格对标的资产价格、波动率、时间等的敏感程度,包括delta、gamma、vega、theta和rho。
2. 期权隐含波动率:根据期权市场价格反推出的标的资产预期波动率。
3. 期权价格:期权合约的市场价格。
4. 期权价值:期权合约的内在价值和时间价值之和。
5. 期权合约交易量:某一期权合约的交易量,反映市场对该合约的关注程度。
6. 期权合约持仓量:某一期权合约的持仓量,反映市场对该合约的看涨或看跌预期。
三、期权风险管理数据元素1. Delta敏感度:期权合约价格对标的资产价格变动的敏感程度。
2. Gamma敏感度:Delta值对标的资产价格变动的敏感程度。
3. Vega敏感度:期权合约价格对标的资产波动率变动的敏感程度。
4. Theta敏感度:期权合约价格对时间流逝的敏感程度。
5. Rho敏感度:期权合约价格对无风险利率变动的敏感程度。
四、期权交易策略数据元素1. 多头/空头:投资者买入期权合约即为多头,卖出期权合约即为空头。
2. 开仓价:投资者建立新头寸的价格。
3. 平仓价:投资者平仓头寸的价格。
4. 止损价:投资者设定的止损价格,用于控制风险。
5. 盈利目标价:投资者设定的盈利目标价格,用于确定止盈点。

– 使用GET方式来进行异步请求
• 参数:
– url (String) : 发送请求的URL地址. – data (Map) : (可选) 要发送给服务器的数据,以 Key/value 的键值对形式表示,会做为 QueryString附加到请求URL中。 – callback (Function) : (可选) 载入成功时回调函数 (只有当Response的返回状态是success才是调用 该方法)。
• url String (默认: 当前页地址)
– 发送请求的地址。
• type String (默认: "GET")
– 请求方式 ("POST" 或 "GET"), 默认为 "GET"。
• timeout Number 设置请求超时时间 毫秒
– 此设置将覆盖全局设置。
• async Boolean (默认: true)
• • • •
error (Local Event) 请求发生错误 ajaxError (Global Event) 请求发生错误 complete (Local Event) 请求完成 成功||失败 ajaxComplete(Global Event)请求完成 成功|| 失败 • ajaxStop (Global Event) 请求停止
• error Function
– (默认: 自动判断 (xml 或 html)) 请求失败时将调 用此方法。 – 这个方法有三个参数:
• XMLHttpRequest 对象, • 错误信息, • (可能)捕获的错误对象。
function (XMLHttpRequest, textStatus, errorThrown) { // 通常情况下textStatus和errorThown只有其中 一个有值 this;}
• jQuery.post( url, [data], [callback], [type] )
– 使用POST方式来进行异步请求
• 参数:
– url (String) : 发送请求的URL地址. – data (Map) : (可选) 要发送给服务器的数据,以 Key/value 的键值对形式表示。 – callback (Function) : (可选) 载入成功时回调函数 (只有当Response的返回状态是success才是调用 该方法)。 – type (String) : (可选)官方的说明是:Type of data to be sent。其实应该为客户端请求的类型 (JSON,XML,等等)
Ajax
内容简介
• Ajax 简介 • XMLHttpRequest 对象 • 使用XMLHttpRequest
• Asynchronous JavaScript and XML
Ajax 的定义
XMLHttpRequest 对象
• AJAX技术的核心对象 • 存在于所有主流浏览器中
– IE 5.5 – FireFox1.0+, Safari, etc – IE6.0+ Microsoft.XMLHTTP XMLHttpRequest Msxml2.XMLHTTP
• ajaxStart (Global Event)
– 一个Ajax请求开始,并没有其他的Ajax请求当前 正在运行的。 • ajaxSend (Global Event) 请求之前运行。 • success (Local Event) 请求成功 • ajaxSuccess (Global Event) 请求成功
"AjaxEvent.js", function(){ alert("AjaxEvent.js ");} );
jQuery Ajax 事件
• 局部事件 局部事件就是在每次的Ajax请求时在方法内 定义的 • $.ajax({ beforeSend: function(){ // Handle the beforeSend event }, complete: function(){ // Handle the complete event } // • });
• $.get(
"./Ajax.aspx", {Action:"get",Name:"lulu"}, function (data, textStatus){ //返回的 data 可以是 xmlDoc, jsonObj, html, text this; // 在这里this指向的是Ajax请求的选项配置信息 alert(data); //alert(textStatus);//请求状态:success,error等 等。 //alert(this); });
– 预期服务器返回的数据类型。 – 如果不指定,jQuery 将自动根据 HTTP 包 MIME 信息返回 responseXML 或 responseText,并作为 回调函数参数传递,可用值: – "xml": – "html": – "script": – "json": – "jsonp": JSONP 格式。使用 JSONP 形式调用函数 时,如 "myurl?callback=?" jQuery 将自动替换 ? 为正确的函数名,以执行回调函数
• 全局事件 全局事件是每次的Ajax请求都会触发的,它 会向DOM中的所有元素广播,在上面 getScript() 示例中加载的脚本就是全局Ajax 事件。 • $("#loading").bind(
"ajaxSend", function(){ $(this).show(); }).bind("ajaxComplete", function(){ $(this).hide(); });
• String getResponseHeader(Stringheader) • String getAllResponseHeaders()
Cookie操作
• document.cookie = cookie;
– cookie=cookieName + "=" + encodeURIComponent(cookieValue); – setCookie("request-data", "Hello World"); – getCookie("response-data");
“json”);
• jQuery.getScript( url, [callback] )
– 通过 GET 方式载入并执行一个 JavaScript 文件。
• 参数 • url (String)
– 待载入 JS 文件地址。
• callback (Function)
– (可选) 成功载入后回调函数
Hale Waihona Puke • $.getScript(
• processData Boolean (默认: true)
– 默认情况下,发送的数据将被转换为对象 以配 合默认内容类型 "application/x-www-formurlencoded"。如果要发送 DOM 树信息或其它 不希望转换的信息,请设置为 false。
• dataType String
• global Boolean (默认: true)
– 是否触发全局 AJAX 事件。设置为 false 将不会 触发全局 AJAX 事件,如 ajaxStart 或 ajaxStop 。 可用于控制不同的Ajax事件
• ifModified Boolean (默认: false)
– 仅在服务器数据改变时获取新数据。使用 HTTP 包 Last-Modified 头信息判断。
• Function onreadystatechange 需要执行的回 调函数
• • • •
String responseText 获取返回的数据 XmlDocument responseXML 获取返回的数据 Number status response的状态代码 200 String statusText 字符串形式信息
• 提供了异步访问服务器端的能力 • 首次出现在IE5.5中(ActiveX)
方法
• void open(Stringmethod, String url, Boolean async)
– Stringmethod 请求的方式 POST 或者 GET – url 发送的url请求的路径 – Async 是否使用异步回调 – 示例 – Get方式 open(“get”,”url?par=”+value,true); – Post方式 open("POST", url, true);
• void send(Stringbody) • void abort()
• 属性: • Number readyState
操作状态
– 0请求没有发出(在调用 open() 之前)。 – 1请求已经建立但还没有发出(调用 send() 之前) – 2请求已经发出正在处理之中(这里通常可以从 响应得到内容头部) – 3有部分数据可用,但是服务器还没有完成响应 – 4响应已完成,无论成功还是失败
• cache Boolean (默认: true)
– false 将不会从浏览器缓存中加载请求信息。
• complete Function
– 请求完成后回调函数 (请求成功或失败时均调用 )。参数: XMLHttpRequest 对象,成功信息字 符串。function (XMLHttpRequest, textStatus) { this;}
