摘要: 摘要 天然气相态研究中平衡常数Ki的精确计算所涉及的K—循环,其终止判据过去多采用,经过多种实际运算表明改用|En+1/En-1|≤σ为宜。

关键词: 天然气, 相态研究 平衡常数, K—循环

Abstract:

In the research of the phase state of natural gas,the ending criterion of the K-cycle in calculation of equlibrium constant ki used to adopt; It has proved through calculations that the ending criterion using |En+1/En-1|≤σ is right.

Key words: gas, phase State, equilibrium constant, K-cycle
