在近期的技术改造[2]中，我们研制出电阻臂可变的自动平衡电桥，重新研制了双薄膜测热电阻，建立了射频电压自动校准系统，从而使该基准的计量性能有了很大提高，其主要技术指标如下：测量范围为0·1~2·0V；频率范围为10~3 000MHz；不确定度为0·25%~0·7%(k=3)；工作方式为自动测试。2工作原理和构成2.1工作原理射频电压基准是建立在功率替代原理的基础

When in the Erase, 28F001 based on Byte for the smallest units modified; in the write data, chip programming to add a certain voltage, and BOOT BLOCK erase block data to be combined with the deletion of a specific voltage.

在擦除时，28F001是以Byte为最小修改单位的；在写入数据时，芯片上要加上一定的编程电压，并且BOOT BLOCK块内数据的擦除要加上特定的删除电压。

The electropinning parameters (voltage, concentration and C-SD) influenced the mechanical properties of electrospun nylon 6 fiber mats. With increase of the solution concentration, the breaking stress and strain of the mat became large. The effect of C-SD was contrary. The nylon 6 fiber mat electrospun on the high voltage had low elongation but high strength.

静电纺尼龙6纤维毡的断裂强度和断裂伸长率随着浓度的增加都有增加的趋势；随着电压的增加，其断裂强度先减小后增大，断裂伸长率随电压增加而降低；断裂强度、断裂伸长率和断裂比功随着C-SD的增加都有减小的趋势。

This paper gives out the principles and improving schemes of transformer discharge equipment and resonance booster discharge equipment. By detecting the current in the main circuit, the gap's breaking-down can be identified, and the single chip micro-computer will send out corresponding control signal to make the IGBTs to switch off or cut off the input voltage, by this mean, we can make sure that every time of the experiment, the sample will discharge only once. The paper also introduces the principle of the protection circuit. At last, the experimental waveforms were listed, which prove the feasibility of the high voltage discharge fast switch-off device.

该文给出了变压器和谐振升压器2种高压放电试验装置的原理以及改进方案，通过检测主回路电流大小判断间隙是否被击穿，由单片机发出相应控制信号，采用IGBT等开关器件控制试验电压的通断，保证了试品每次试验只进行一次放电，介绍了保护电路的原理，给出了试验波形，证明了此高压放电速断装置的可行性。

This error voltage serves as is controls the electric charge pump breakover resistance (to call that it controls resistance pressure), then obtained a stable output voltage.

这个误差电压被用作是控制电荷泵导通电阻，进而获得了一个稳定的输出电压。

Overvoltages are initially clipped by breakdown clamping until the voltage rises to the breakover level, which causes the devices to crowbar into a low-voltage on state.

保护器由一个匀称电压触发型双向交流二极管组成，过电压最初被弱钳位剪除址到电压上升至超过的级别，该级别会造成装置进入一个低电压开启状态。

This topic returns in view of the cut type switch spreads the type switch "to return for the predecessor design spreads the type electric power switch utilization in the LED lamps and lanterns" is the research direction, to achieve take reduces the power loss to replace the tradition operational amplifier pulse wave width accent as the goal using IC UC3842 changes part, the actuation returns spreads the type electric power switch's switch of Power MOSFET, so as to controls instead spreads the type electric power switch breakover closure's time then control voltage output size, achieves the output voltage to the load LED lamps and lanterns adjusts the LED lamps and lanterns brightness the goal.
