This principle has been used for many years in a wide variety of vibration generators . 这一原理多年来被广泛用在各种各样的振动发生器上。
Colored circles on the map denoted kidney dialysis machines, oxygen generating units, iron lungs and similar apparatus . 图面上彩色的圆圈表示肾透析机,氧气发生器,铁肺以及诸如此类的装置。
He used an oscillating circuit containing a spark gap as a generator, and a similar circuit as a detector . 他利用一个振荡电路,其中包括一个电花隙作为发生器,并用另一个相似的电路作为探测器。
Also, in prior years, adjustment of the signal-generator and torque-generator stator mechanical radial positions was required . 前些年对信号发生器和转矩发生器定子的机械半径位置也要进行调整。
The sparker was originally developed for fundamental studies of underwater sound propagation and of subbottom geology . 火花发生器原来是为了进行关于水下声波传播及海底地质的基础性研究而制造的。
