调谐机构 meaning in Chinese

tuning gear
tuning mechanism

For the first time , three types of sine structures for wavelength linear scale in grating spectrum instruments are described systematically . the tuning structures for wavelength linear scale in both littrow and littman set - up external - cavity laser diodes are designed
( 3 )首次系统地分析了光栅光谱仪器中的三类正弦机构，分别设计了可实现波长线性标度的littrow和littman外腔半导体激光器调谐机构。
At the same time we based on the high precision tuning mechanism and computer controlling feed - back technology to design pid controller . so , we finished design of closed - circuit controlling system and achieved the goal of sampling and feedback
同时，本文在高精度的调谐机构的基础上，利用计算机控制反馈技术，设计了速度式pid控制器，完成了闭环反馈控制系统的设计，实现了输出参量光信号采集和反馈的目的。
