Transformation of motor ' s cooling fan variable - frequency system and the results 机组冷油器系统改造
In the paper , the emphasis is placed on the discussion of the algorithm of design and simulation of digital intermediate frequency system 本文主要研究了数字中频系统中的信号处理、设计及其仿真方法。
This kind of control system can achieve such a good performance as the dc motor does and is often called self - controlled varying frequency system 这样,永磁电机可以获得与直流电机类似的调速性能,通常称为自控频率调速。
This text for the test of the numerical video frequency system , the diagraph principle and method of the logarithms word video frequency signal carry on a study . 本文就数字视频系统的测试,对数字视频信号的测量原理和方法进行探讨。 ”
The high frequency system in rdg that we study is complete overmoded sws , and the diameter of waveguide is much larger than the wavelength inspired by the device 由于我们研制的相对论绕射辐射振荡器采用完全过模的慢波结构作为高频系统,波导的直径远大于激励波的波长。
