摘要
以孔板φ８０ｍｍ测流中１０组孔板流量ｑｖ和孔板差压随机数据为例，用数理统计法证明孔板流量呈正态分布；导出孔板流量系数ｋ值一般计算方法；最后证明孔板流量ｑｖ和孔板差压线性回归效果极显著．
Taking the stochastic data of 10 groups of orifice plate flow qv and orifice platepressure difference as an example and using the mathematical statistics method, it is provedthat the normal distribution is appeared in the orifice plate flow.The general computationmethod for the orifice plate coefficient k is derived. Finally,it is also proved that the linearregression effect is very obvious.
