... 进水口的设计原则是：尽量避免在塘内产生短流*(short-circuiting)、沟流*(channeling)、返混*(backmixing)和死区(dead area)，使塘内水流状态尽可能接近推流，用富氧水团推出池塘内低含氧水团。池塘长宽比推荐为4比1。

The protector of electromotor have used heat relay for a long time, but heat relay not only has a dead area in the light over-loading area, but also can't protect open phase under so much circumstances.
电动机保护装置采用热继电器已有很长的历史，但热继电器在电机的轻过载区存在着“保护死区”，而且对断相保护在许多情况下起不到保护作用。
