本文主要介绍了IGB T的应用电路，和当发生击穿放电时 IGB T 过电流的限制及其保护电路，实现高频高压脉冲电源的整体设计。

The primary frequencyregulation has direct effect on the grid frequency, and it is very important to maintain thestability of power systems.

一次调节直接影响电网的频率质量，对电网的稳定起着重要的作用。

Frequency response characteristic of power system is an important parameter for AGC.

电力系统自然频率特性系数是 AGC控制中的一个重要参数。

The power to expose most high frequency transmitters, as well as more common VHF and UHF bugs, is now in the palm your hand.

暴露的权力最高频发射器，以及更常见的高频和超高频的错误，是在手掌你的手了。

The previous researches have been done experiments mostly in the Water tank. In order to simulate turbulence of flow in river and research its characteristics, the characteristics of turbulence are studied by experiments in the water channel with ADV technique. The research results indicate that R.M.S. velocity linearly relates to the oscillating-grid frequency; R.M.S. velocity decays by power exponent relates to the distance from the grid midplane; and the relationship between the geometrical factors and the free movement space of water is direct proportion.

以往研究大都在水箱中对振动格栅紊流特性进行实验研究，为能模拟天然河道中的紊流，研究天然河道中紊流特性，利用ADV技术在水槽中对振动格栅紊流进行了实验研究研究结果表明：均方根速度与格栅振动频率成线性关系；均方根速度与距格栅中平面的距离成幂指数关系衰减；几何系数与水的自由运动空间成正比关系。
