节流效应 meaning in English

throttling effect

This paper offers a method that can avoid the incorrect or rough methods mostly accepted now , and this method considers the temperature change along pipeline , the difference of friction loss in turbulence zone and the throttle effect in cross - section of reduced pipe
针对现有的静态仿真算法存在的错误和不足，提出了一种更为精确的仿真算法，该算法除考虑了管道沿线的温度变化、处于不同的紊流区摩阻损失的大小不同之外，还考虑了变径管道在变截面处存在节流效应等问题。
