Study on Harmonic Current of Compact Fluorescent Lamp Below 25W

25W以下紧凑型荧光灯的谐波电流对策研究

When the heat load is 25w , regardless of the direction of the acceleration , the operation temperature of the LHP will increase with the increase of acceleration .

当热载荷为25W时，不管蒸发器内工质流动方向与加速度方向是否相同，蒸发器运行温度都是随着加速度的增大而增大。

For this reason , accelerated life tests of the 12V 25W double filament signal lamps as well as preliminary studies on the average life and life distribution of signal lamp bulbs are conducted by the author .

为此，笔者做了12V25W双丝信号灯泡的加速寿命试验，对信号灯泡的平均寿命、寿命分布做了初步探讨。

The hardness of the spindle bottom can get to 1205HV_ ( 0.1 ) at proper scanning speeds and 25W / mm ~ 2 of power density . The hardening layer is homogeneous enough .

在25W/mm~2激光功率密度下，和适当扫描速率下GCr15钢锭底硬度高达1205HV（0.1）且硬化层均匀。

In the end of this paper , a hardware prototype of 25W (( 3.3 ) V / 8 A ), which applied the synchronous rectification to the flyback converter , has been built and some waveforms have been given .

文章最后给出了采用PWM控制、输出3.3V/8A的同步整流反激变换器的实验波形。

The results show that the hardness of bearing roller is lower than the required because no martensite is formed when the quenching time is 55 min and the quenchant is the oil or UNCON ( 25w % ) .

结果表明：淬火时间为55min，淬火介质为油或UNCON（25%）时，支承辊不能得到马氏体而硬度降低；

From the largest temperature-time curves there can be seen that semiconductor-cooled composite phase chang silicon mirror can restore the temperature of mirror and elastic deformation to their start for 5s in the 25W of refrigerating output under 20 ℃ of environment temperature and 100W of net absorption heat quantity .

由最大温度时间曲线可知，在净吸收热量为100W、环境温度为20℃，制冷量为25W时，半导体致冷复合相变硅镜只需5s就可使镜体的温度和弹性变形恢复至初始状态。
