用数理统计和回归分析手段，对ＧＢ／Ｔ１３００６－９１“泵汽蚀余量”图线整理和分析，通过大量计算，提出每种型式泵的１１条汽蚀余量图线只用一个数学公式表示的方法。比较了汽蚀余量的计算值和标准图线值，计算值平均相对误差较小，完全可以满足实际工作的需要。
Mathematical statistics and regression analysis methods, GB / T13006-91 “NPSH” chart finishing and analysis, through a large number of calculations, proposed for each type of pump 11 NPSH diagram using only a mathematical formula Said the method. Comparing the calculated value of NPSH with the value of standard plot, the average relative error of the calculated value is small, which can completely meet the needs of practical work.
