摘　　要：在恒定等温流、忽略对流项和压缩因子微小变化影响的等坡度管段水力计算解析式的基础上,提出了基于水平管计算结果与附加压力之差的简化式、简化修正式以及各自的适用范围,认为两式可用于城镇燃气管道有高差时的水力计算。认为采用解齐次方程的方法对推导解析式更为严谨。Based on the analytical formula for hydraulic calculation of isogradient pipe section with constant equal temperature flow and ignoring the influence of small changes in convection term and compression factors,the simplified formula,simplified correction formula and their application scope based on the difference between the calculation results of horizontal pipe and additional pressure are proposed.It is considered that the two formulas can be used for the hydraulic calculation of urban gas pipeline with elevation difference.It is believed that the method of solving the homogeneous equation is more rigorous for deriving the analytical formula.
