| 摘 要： | 利用人造流体包裹体数据和甲烷笼合物熔化温度和压力的实验数据获得了在高温高压下H2O-CH4两元系的摩尔体积。并将所得数据与用传统的高温高压设备和状态方程所获得的数据进行了比较。这三组数据均吻合的很好。这表明用人造流体包裹体方法获得流体系统摩尔体积的可行性和已有的状态方程在描述该两元系在高温高压下的摩尔体积的正确性。本项工作对H2O-CH4系统高温高压下实验数据的重要补充。同时将已有的状态方程的适用性推广到更高的温度和压力。

| Abstract: | The molar volumes of the binary system H2O-CH4 were calculated using synthetic fluid inclusion data and a new least square fit equation on experimental data of CH4 clathrate melting temperatures and pressures. Comparisons of molar volumes obtained in the present study with other existing molar volume data from tranditional high temperature and high pressure experiments and with existing equations of state have shown that they agree quite well among themselves. Thus we can extend the suitability of existing equations of state for predicting the molar volumes of the binary system H2O-CH4 to high temperatures and pressures. We also pointed out(I) that care must be taken when we calculate the molar volumes of the binary system with very low methane concentration at relatively low pressures and high temperatures, and(2)that to calculate accurately the molar volumes of the ternary system H2O-CO2-CH4, more experimental data at low temperatures and pressures for the ternary system are needed. |
