This is the basis of the phenomenon called cavitation.

这就是所谓汽蚀现象的根据。

Therefore, this method could be to solve the cavitation problem supporting facilities.

所以，可将该方法作为解决汽蚀问题的辅助方法。

For a long time, the pump cavitation has been regarding as a difficult problem to be resolved.

长期以来，泵汽蚀现象被认为是一个不易解决的问题。

There is no cavitation damage and irrigation water and so on.

不存在汽蚀破坏及灌引水等问题。

Although this method can completely eliminate cavitation problems, but the site is seldom used in the production.

该方法虽能彻底消除汽蚀问题，但在生产现场却很少采用。

This method is more suitable for pump cavitation performance curve fitting.

该方法较适合于泵汽蚀性能曲线的拟合。

If the liquid does not contain any impurities, even at low pressure it does not happen cavitation.

如果液体中不含任何杂质，即使在压力很低时也不会发生汽蚀。

The purpose of this design does not change in the basis of the original equipment used CENTUM CS3000 for the catalytic reforming pre-hydrogenation control devices in order to separate the liquid tank and the stripper pressure control as a priority, design a set of complete control program.

本次设计目的是在不改变原有设备的基础上采用CENTUM CS3000对催化重整预加氢装置进行控制，以分离罐的液位和汽提塔的压力控制作为重点，设计一套完整的控制方案。

The purpose of this design: do not change in the basis of the original equipment used CENTUM CS3000 for the catalytic reforming pre-hydrogenation control devices in order to separate the liquid level and tank pressure stripper tank and return level control focus on the design of a complete set of control programs.

本次设计目的：在不改变原有设备的基础上采用CENTUM CS3000对催化重整预加氢装置进行控制，以分离罐的液位以及汽提塔的压力和回流罐的液位控制作为重点，设计一套完整的控制方案。

The design purpose is not changing the original equipment on the basis of CS3000 CENTUM of catalytic reforming, advance hydrogenation to separator level and stripper pressure control, design as a complete set of control plan.

本次设计目的是在不改变原有设备的基础上采用CENTUM CS3000对催化重整预加氢装置进行控制，以分离罐的液位和汽提塔的压力控制作为重点，设计一套完整的控制方案。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
