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 steady-state operating characteristics of the proposed DC-DC converter topology are illustrated and discussed on the basis of the simulation and some experimental results of 2kW-4OHz breadboard set up.

不过，大部分的零电压开关PWM DC - DC变换器发达以前，包括一些弊端，如负荷依赖软开关运作，相对狭小的范围和零电压转换器效率降低，由于大循环电流流经。

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 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。

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.

各位大大抱歉~！因为英文底子不好！希望大家帮忙翻译一下，希望不要用翻译软体翻的最好是自己翻！拜托了！本专题针对切换式转换器的返驰式转换器为前身设计「返驰式电力转换器运用在LED灯具」为研究方向，为达到以减少功率损失为目的利用IC UC3842代替传统运算放大器脉波宽度调变部分，驱动返驰式电力转换器的Power MOSFET之开关，藉以控制反驰式电力转换器导通截止的时间进而控制电压输出的大小，输出电压至负载LED灯具达成调节LED灯具亮度的目的。
