| 摘 要： | 通过X-射线断层扫描系统(CT)开展甲烷水合物生成和分解试验研究,结果表明:CT可以清楚地描述甲烷水合物形成和分解过程.通过生成和分解的密度图像变化和CT数频率分布以及均方差变化,能够较好地理解甲烷水合物的生成和分解过程变化,同时CT数在生成和分解过程中的变化有助于准确地判断甲烷水合物的生成和分解的相平衡条件.

| Abstract: | The experimental research of formation and decomposition processes of methane hydrate by computerized tomography(CT) is expatiated on in this article.It is proved by the research that CT could describe the formation and decomposition processes of methane hydrate distinctly.The processes of formation and decomposition of methane hydrate can be well comprehended from the density changes shown in CT images and the frequency distribution and the mean variance change of CT value.And also,the changes of CT value during formation and decomposition processes are helpful for accurately judging the phase balance conditions of methane hydrate. |
