通过凝胶时间测定分析单体的含量、交联剂与单体的配比、引发剂的用量以及聚合反应温度来对凝胶过程的影响，通过弯曲强度测试及扫描电镜分析不同交联剂与单体配比下凝胶注模成形的蔗糖碳前驱体的坯体强度及微观结构。
结果表明：丙烯酰胺质量分数28%，N,N -亚甲基双丙烯酰胺质量分数8.4%，引发剂过硫酸铵质量分数2%，50 ℃的聚合温度下，体系的凝胶时间可以控制在 60~130 s 之间，满足凝胶注模成形所需要的操作时间。
上述单体聚合条件下，添加蔗糖50 g、造孔剂120 mL，制备的前驱体弯曲强度为0.46 MPa，SEM 图像显示前驱体当中的造孔剂颗粒均匀，完整性好，同时蔗糖及凝胶包裹在造孔剂周围，连接强度高。

汽轮机数字式电液控制系统汽轮机数字式电液控制系统（DEH系统）是电站汽轮发电机组不可或缺的重要组成部分，是汽轮机启动、停止、正常运行和事故工况下的调节控制器。
DEH系统通过控制汽轮机主汽门和调故的调节控制系统通过控制汽轮机主汽门和调节汽门的开度，实现对汽轮发电机组的转速、负荷、压力等的控制。
控制汽轮机数字式电液控制系统分为计算机控制系统和液压控制系统两大部分。
其中计算机控制系统用于实现DEH的各种功能并发出指令使各蒸汽阀门动作，液压控制系统（EH系统）用于接收计算机控制系统的指令并驱动各蒸汽阀门动作。
EH系统的组成EH系统是汽轮机数字式电液控制系统--DEH中的一个重要部分，它主要由供油系统、执行机构和危急遮断系统三大部分组成。
•供油系统是一个EH油贮存和处理中心，并向EH系统提供稳定的高压油，以此来驱动执行机构；附图是目前电厂行的典型的汽轮机高压抗燃油以此来驱动执行机构；附图是目前电厂运行的典型的汽轮机高压抗燃油纯电调EH系统液压原理图；•执行机构响应从DEH送来的电指令信号，以调节汽轮机各蒸汽阀开度。
送来的电指令信号以调节汽轮机各蒸汽阀开度•危急遮断系统是由汽轮机的遮断参数所控制，当这些参数超过其运行限制值时，该系统就关闭全部汽轮机蒸汽进汽阀门，或只关闭调节汽阀，制值时该系统就关闭全部汽轮机蒸汽进汽阀门或只关闭调节汽阀以保证汽轮机正常安全运行。
供油装置供油装置的主要功能是提供执行机构所需要的液压油及压力，同时保持液压油的正常理化特性和运行特性供油装置由以下部套组成时保持液压油的正常理化特性和运行特性。
UL_1007电子线说明
UL1007电子线
UL1007电子线,英文为：ELECTRICWIRE1007,是指美国UL认证下的一种型号，目前，该线主要用在弱电工程，如电子科技、电器设备、收银机、计时器、医疗仪器、电器设备、手机、数码相机、机顶盒、复印机、传真机、仪器仪表、电源、充电器、马达、音响、显示器、空调、冰箱、医疗设备、教学设备、玩具、汽车、家用电器以及电路板等产品的连接领域。
AWG是美国导线规格，美国区分导线直径的标准又称B&S线程（即Brown&Sharps线程）铜线直径通常以AWG作为单位进行测量。
AWG前面的数值（如24AWG、26AWG）表示导线形成最后直径前所要经过的孔的数量，数值越大，导线经过的孔就越多，导线的直径也就越小。
粗导线具有更好的物理强度和更低的电阻，但是导线越粗，制作电缆需要的铜就越多，价格就会越贵。
电缆设计的挑战在于使用尽可能小直径的导线，减小成本和安装复杂性，同时还要保证在必要电压和频率之下实现导线的最大容量。
其通用标称是以AWG（AmericanWireGauge）为单位，内部导体按正常标准应分裸铜和镀锡铜两种，常用正规线材的线径规格见下表：。

The additional components are highlighted with green boxes below.3Operating Instructions3.1Battery InsertionTo insert batteries, remove two black covers on top of theinstrument by pressing in and turning 90° anti-clockwise.Three size AA batteries should be inserted in each tube withthe positive (tip) terminal upmost.Note that if the optional battery charger is to be used, thennickel metal hydride (NiMH) rechargeable batteries must beused in the instrument.3.21006/1007 mV Source OperationTo operate both models as a mV source, follow the steps below:POLARITY SWITCH NOTE:On the 1006, the “off” polarity position disconnects the output & provides a short circuit on the output terminals. On the 1007, the “off” polarity position provides an open circuit on the output terminals. This is to prevent accidental shorting of the voltage under test when the unit is being used as a potentiometer. It is desirable to keep the Null “SENSITIVITY” control set to minimum (fully anti-clockwise) when the 1007 is used as a source.3.31007 mV Potentiometric Null OperationDue to the extreme sensitivity of the electronic null detector (3 µV/div.) it is important to ensure that it is correctly zeroed before attempting accurate measurements.3.3.1Zero Setting Procedure3.3.2Measuring Procedure4Servicing and Calibration4.1Internal Preset ControlsIMPORTANT NOTE:These controls are set in the factory before shipment and normally will not require readjustment.If readjustment is considered necessary, it is important to check that the amount of adjustment required is within the range of the trimmer concerned. If it is greater than the trimmer range, there is no point in attempting to readjust and a fault condition will exist in the unit. The range of adjustment of the trimmers is given below. Access to the 1006 or 1007 is by removing the blue case cover which is located by 8 screws.1006 DC mV SourceThe 1006 contains 4 (3 on instruments with serial number earlier than 1320) internal preset trimmers. They are located on the range switch selector module.Zero TrimmerThe ‘ZERO’ trimmer adjusts the circuit zero and is set to bring the output voltage (with all digits set to zero) within the specified limits.Calibration TrimmersThe 1 V, 100 mV, and 10 mV ‘CAL’ trimmers adjust the full-scale calibration (i.e. 9999) on all 3 ranges respectively to within the specified limits.It is important to set the ZERO before attempting calibration.4.2Calibration and AdjustmentTest Equipment Required1) A microvoltmeter with a resolution of better than 5 microvolts.2) An accurate DC voltage source with a range 0 to 1 V, accuracy better than 0.02 %.Zero Setting ProcedureSwitch unit on and check battery condition is good.1) Select 99.99 mV range and set all digits to zero.2) Select ‘NORMAL’ output polarity.3) Connect microvoltmeter to output and adjust ZERO trimmer for less than 10 µV reading.The maximum amount of adjustment available on this trimmer is approximately ± 100 µV.5)Check the zero reading for all three ranges. The readings should be as follows:9.999 mV range less than ± 2 µV99.99 mV range less than ± 10 µV999.9 mV range less than ± 100 µVFS Calibration/Adjustment Procedure1) Check zero output is correct as described earlier.2)Select 999.9 mV range and ‘normal’ output polarity.3)Set output digits to 9999.4)Connect the accurate voltage source and microvolt null meter to the 1006 output in apotentiometric mode.5) Set the voltage source to 999.9 mV output and adjust the ‘1V CAL’ trimmer on the moduleto bring the 1006 output within specification. The maximum amount of adjustmentavailable on this trimmer is 0.8 %.6) Select 99.99 mV range on the 1006 and set the voltage source to 99.99 mV. Adjust the‘100mV CAL’ trimmer to bring the output within specification. The maximum amount of adjustment available on this trimmer is 0.8 %.7) Select the 9.999mV range on the 1006, and set the voltage source to 9.999 mV. Adjustthe ‘10mV CAL’ trimmer bring the output to within specification. The maximum amount of adjustment available using this trimmer is 0.8%.8)The specified FS allowable errors for these three ranges are:999.9mV range less than ± 550uV at full scale output.99.99mV range less than ± 55uV at full scale output.9.999mV range less than ± 6uV at full scale output.Note: All instruments with serial numbers earlier than 1320 do not have the additional trimmer fitted to adjust the 9.999mV full scale calibration of the 10mV range. See item 9 below.9)The 9.999mV range is obtained by resistive attenuation of the 999.9mV range. A 100:1 attenuation ratio is used and adjustment is by preselected resistor values. Unless overload damage to the attenuator resistors has occurred, the calibration of the 1-volt range will automatically ensure the full scale calibration of the 9.999mV range.1007 Millivolt Source and PotentiometerThe 1007 incorporates a 1006 with the addition of a microvolt null detector. With the front panel function switch in the ‘SOURCE’ position, the unit operates as a 1006 and the ZERO and CALIBRATION setting procedures are identical to those for the 1006.The potentiometer position of the function switch connects a high performance null balance system in series with the output. The null zero and sensitivity are adjustable by front panel controls. Maximum sens. = ± 20 µV. Min. sens. = ± 200 mV and zero adjust range is approximately ± 100 µV.The null amplifier circuitry is located on a small pcb which is fixed to the underside of the output terminals. The circuitry incorporates two preset trimmers for adjustment of the null amplifier input voltage and current offsets.Important Note: It is important to check that the 1007 is operating correctly as a millivolt source and that the source zero setting is within specification before considering readjustment of the null amplifier trimmers.Null Amplifier trimmer adjustment procedureVoltage Offset (10k trimmer):1) Select ’ZERO’ position on the function switch.2) Set all digits to zero. Select 9.999 mV range.3) Adjust trimmer for equal swing (about zero) of the front panel zero control.Current Offset (500k trimmer):1) Select ’ZERO’ function, all digits zero, 9.999 mV range.2) Select potentiometer operation.3) Connect a 47 kilohm resistor across output terminals.4) Set the null sensitivity control to minimum.5) Adjust trimmer for zero reading on the null display - the null sensitivity can be increased gradually to maximum during adjustment.Note: A low offset current is important when measurements are to be made in high resistance circuits, but will not affect accuracy of measurements in low resistance circuits.5Warranty and ServicingWarrantyTime Electronics products carry a one-year manufacturer’s warranty as standard.Time Electronics products are designed and manufactured to the highest standards and specifications to assure the quality and performance required by all sectors of industry.

大汉 4100 型 HF 无线 FAX 数据调制解调器使用手册说明书
Send FAX images without phone lines or satellite communications! The HAL Communications FAX-OVER-FAX-4100HF FAX Over Radio SystemBasic FAX-OVER-RADIO SystemSYSTEM COMPONENTS:The HAL FAX-OVER-RADIO S ystem is simple and makes maximum use of your G3 FAX machine and SSB HF station. Add the DSP-4100 and FAX-4100 and you’re on-the-air with FAX.Virtually all modern S S B HF transceivers may be used for FAX. The 500 to 2500 Hz spectra of CLOVER-2000 is directly compatible with S S B radio passbands. Special bandwidth filters or super phase-linear filters are not required. The +50 Hz fre-quency tolerance is compatible with virtually all modern synthesized S S B equipment. S tandard 100Watt transmitters and simple antennas (1/2 wave dipoles or 1/4 wave verticals) are all that is needed for most FAX-OVER-RADIO links.Note that all HAL units operate from “nominal”12VDC (10 to 18 VDC, in fact). The HAL FAX-OVER-RADIO system is a very good choice forCOMPUTERS & OTHER EXPANSION:The basic FAX-OVER-RADIO system does not require a computer at either end. All control func-tions and data communications are handled within the HAL FAX-4100 and DSP-4100/2K. This makes for a very low-cost and simple system for remote areas where a computer is not required nor desired. However, a computer can easily be added to the communications link. This allows use of CLOVER-2000 for all forms of data. If you wish to design cus-tom software, the computer may also be used for fur-ther data compression, communicationwith the radio control port, or other control functions. The DS P-4100/2K includes a second serial I/O port which may be used to connect to the control port of the HF radio, eliminating the need for a second serial port from the computer - a serious problem for lap-top PC’s. Standard phone line and data circuit connec-tors are used to keep installation simple.。
