查询词典 measuring

Since it is usually necessary to de-energize the winding before measuring R H, and the resistance of the coil may change rapidly as the temperature decreases, it may be necessary to determine the value of R H at the end of the test by taking several resistance measurements at short intervals, beginning as quickly as possible after the instant of shutdown.

人们一般在测R H时，通常要断掉线圈绕组的电，温度下降了线圈的电阻变化很快，所以有必要在断电的一瞬间尽快地测取电阻，而且还要以较小的时间间隔多测几次，从而得到R H 值。
