摘　　要：本文主要根据微灌灌水器的基本水力特性和一般通用的水力学计算公式q=KH^z,用最小二乘法原理和统计学的基本概念,推导出了灌水器的流态指数x、相关系数R和制造偏差C_(?)的计算方法并编制了计算程序。最后列出国外对各种型式灌水器制造偏差范围与产品的优劣分类方法。供开发研制、水力测试和工程设计人员参考。Based from the hydraulic characteristics of the emitter and general hydraulic formula——q=KH^z ,This paper has deduced the calculation method for flow stance index x , correlation coefficient R and manufacturer's coefficient of emitter variation C. and from the principle of method of the least sauares and the basic concept of statistics, and has programmed their calculating procedure. Finally the range of manufacturing variation for various emitters and the classification for distinguishing the products abroad are listed for reference
