摘　　要：国家标准GB/T 17747.2附录B的(B.6)公式中,累加项前系数为1,但对照国际标准ISO 12213-2附录F的FORTRAN程序,它的系数值是2。为此采用Octave编程语言对天然气压缩因子和密度的计算进行了仿真,结果显示,采用系数1和2都能够满足应用要求,但采用系数2有更高精度。此外,考虑有关计算软件的成本,采用符合IEC 61131-3编程语言的功能块图编程语言实现了上述天然气压缩因子和密度的计算,并与实验结果一致。In the formula(B.6)in Appendix B of National Standard GB/T 17747.2,the coefficient before the accumulation term is 1.However,compared with the FORTRAN program in Appendix F of the international standard ISO 12213-2,its coefficient value is 2.In the paper,the calculation of the compression factor and density of natural gas were simulated by using the Octave programming language.The results showed that both coefficients 1 and 2 could meet the application requirements,but coefficient of 2 had higher precision.In addition,considering the cost of the calculation software,the above calculation of compression factor and density of natural gas was implemented in this paper by using function block diagram programming language conforming to IEC 61131-3 programming language,and the results were consistent with the experimental results.
