题目

英语翻译
通常负载在接通或断开电源电压的时候,是一个突变的过程,对于一些用电器来说,电流的变化量过大过快,容易造成不利的影响,如轻则烧坏保险丝,重则使白炽灯等瞬间损坏的现象也常见.本文通过对电路的重新设计,使电源在开启与关闭时以阶梯上升或阶梯下降的方式进行,且上升与下降的时间可方便和任意地改变,从而对用电路设备起到有效的缓冲保护作用.

答案

Load on or off when the power supply voltage,Its a mutation process ,for some appliances,the rapid change in current is too large,is likely to cause adverse effects,such as ranging from burned fuses,Power so incandescent moments damage phenomenon is also common.Through the redesign of the circuit,so that when you turn the power on and off the ladder to rise or fall stepped manner,and rise and fall times can be easily and arbitrarily changed,and thus the circuit protective devices play an effective role in cushioning .
