摘要
给出了一种新的氢蚀甲烷气泡压力与逸度关系的热力学分析方法，计算结果表明，当甲烷逸度较低时，压力与逸度近似相等；逸度高于８０ＭＰａ时，压力随逸度的增加变得愈来愈缓慢。另一个特点是甲烷压力与温度关系不敏感，温度对压力影响不显著。对计算结果进行了分析。
A new thermodynamics method to the analysis of the relationship between pressure and fugacity of methane gas in hydrogen attacked bubbles is given.The calculating results show that the methane pressure P CH 4 equals approximately to the methane fugacity f CH 4 when f CH 4 is smaller.The increase of f CH 4 becomes slower with the increase of P CH 4 when f CH 4 is higher than 80MPa.P CH 4 is not sensitive to the exposed temperature.The calculating results is analyzed.
