摘　　要：明确了环状干线、输送干线和枝状支线的概念与水力计算次序,提出了拟定环状干线流向的原则和进行流量初始分配的方法,建立了环状干线水力平差的数学模型,定义了节点参考压力的概念,并推导出计算节点参考压力的方程组及其矩阵表达式.在此基础上,开发了环状干线水力平差计算程序,给出了计算枝状支线资用动力的方法.The authors definitely make out the concept of loop main pipeline, supplying main pipeline and ramiform branch line, as well as the order of their hydraulic calculation. Then they puts forward the principia of how to study out the direction of loop main pipeline and presents the method of making flux initial distribution. The matrix of loop main pipeline hydraulic square dispersion is set up. The node referenced pressure is defined and the equation of how to calculate it is deduced. A software is developed to calculate the loop main pipeline hydraulic square dispersion. The method of calculating ramiform branch margin impetus is given.
