摘　　要：SGERG—88方程是由欧洲气体研究集团推出的用于计算工作状态下天然气压缩因子的状态方程,近期由国际标准化组织推荐为计算工作状态下天然气压缩因子的标准方法。介绍了SGERG—88方程的数学表达式,论述了求解方程的详细步骤,对其在微机上的求解方法也进行了探讨,给出了求解方程的计算框图,并介绍了方程的适应范围及不确定度。SGERG-88 equation was developed by an European gas research group used to calculate thecompressed factor of natural gas under operation. It has recently been recommended as a standard method bythe International Standard Organization to calculate the compressed factor of natural gas in operation.The mathematical evaluation of equation of SGERG-88 equation is described with the exact procedures ofsolving equations, also on micro computers,the range it can be used and the uncertainty.
