天然气水合物的导热系数

Thermal Conductivity of Gas Hydrate

分析介绍了关于水合物导热系数类玻璃体变化规律的三种模型及其相关测试手段、样品制备方法和测试结果。针对物性和测试手段的特点 ,笔者指出在制备测试样品的时候就要注意其生成品质。

The authors analyze and introduce three glass-liked thermal conductivity models, the correlative measurement methods, sample preparation and some results of other authors of gas hydrate. Based on the characteristics of physical properties and measuring methods, the process of forming sample is emphasized in order to show that the remnant gas and ice could affect the result largely. Finally, the correlative experiment results of foreign researchers and our laboratory's result of refrigerant hydrate, which mainly forms structure II hydrate, are compared.
