摘　　要：为提高燃气管网水力计算中局部阻力计算的准确度,采用当量长度法,对常用燃气分配管段进行计算,得到管段局部阻力占沿程阻力的比例。给出了不同情况下管段附件局部阻力占沿程阻力的比例的取值建议表。In order to improve the calculation accuracy of local resistance in hydraulic calculation of gas network, the equivalent length method is used to calculate the usual gas distribution pipeline sections. The proportion of local resistance to the resistance along the pipeline section is obtained. The recommended table for proportion of local resistance to the resistance along the pipeline section is given.

关 键 词：当量长度 局部阻力系数 局部阻力
