在倒U型管垂直段的两端内分别放置一个整流环，来消除入口弯头对垂直段流动的影响。

The fairing rings are built in the inlet and outlet of the vertical parts of inverse U bend respectively in order to restrain the effect of bend on the flow in it.

并以三相半波可控整流电路、滞环比较方式的电流跟踪控制、利用S函数实现空间矢量脉宽调制为例说明了软件的使用方法。

Three-phase half wave controlled rectifier, hysteresis comparison mode current track control, and realization of SVPWM by S-Function are used as examples to describe the usage of the software.
