water hammer effect meaning in English

水锤效应:多普勒探测血管阻塞近端发出的促、尖锐高调的声音

The design of the controller is simple , because the effect of the exciter and the complex relation with system are included in the measurable disturbance . the harmfulness to the generator stability of water hammer effect is overcome by the gahc with the proper function
该方法将励磁调节器的影响和与系统的耦合关系包含在可测扰动变量中，使得控制器的设计只与本地发电机及其调速系统的参数有关， gahc是一种设计简单、安装方便的分散控制器。
The harmfulness to the generator stability of water hammer effect is overcome by the gahc . a device used to regulate speed of rotor and simulate governor system on direct current motor was proposed in the thesis based on phase lock loop technology . the model of steam turbine and hydro turbine had been realized in the governor system of simulating generator by the device
研制开发了一套基于锁相环技术的直流电动机调速与调速系统模拟装置，利用该装置在动模发电机的调速系统实现了汽轮机或水轮机模型的模拟，建立了一套结构开放、稳定可靠、使用方便的研究发电机调速系统控制方法的动模实验系统。
