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。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
