opening rate

The feature and working mechanism of micro-whirling reactor ( MWR) are presented. MWR is used as the core of micro-whirling coagulation and the opening rate control to fit suitable selection of different surface opening diameters is very critical.

介绍了微涡流混凝工艺的核心&涡流反应器的特点及其混凝机理，指出对不同表面开孔直径的选用与开孔率的控制是其技术关键。

It determines the optimum opening rate and opening position. ( 3) Model tests and numerical results are consistent with their difference is within the range of allowable error, and they can confirm each other.

模型试验与数值计算结果相符合，在误差允许范围之内，二者相互印证。

Conclusion: 1. Shanghai university field survival training opening rate quite low.

得出如下结论：1.上海市高校野外生存生活训练课开设率比较低。

It was shown by their results that its all technical indexes such as the overshoot of pressure, opening rate, closing rate, dynamic response time, deviation of pressure regulation met the requirements of practical application.

仿真和实验测试结果表明，新型数字溢流阀的各项技术指标压力超调量、开启率、闭合率、动态响应时间和调压偏差等都满足实际的应用要求。
