摘要
在进行供水管网圆缺型减压孔板工程的设计及管理调度中,常常遇到计算在各种孔板开启高度h情况下的孔板过流问题,通过优化拟合的方法给出了表格参数的替代函数表达式,使计算工作摆脱了表格束缚,计算过程简捷直观。
In the course of design, management and maneuver of segment type of depressed shadow mask project in water supply pipesnet, the problem of flow passing shadow mask during the situation of highness being opened in different mask often comes across. According to the method of optimizing and fitting, this paper shows the altermative function expression for form parameter. This can make computation job slip the leash and make the process more simplified and visual
