摘　　要：精确测量水合物热导率是开发应用水合物蓄冷空调技术的关键之一。限于水合物热物性及其亚稳态特征,相比常规材料,其热导率测量难度大、误差大,导致传统热导率测量方法不能直接用于水合物的热导率测试。综述了瞬态热线法、瞬态平面热源法、稳态平板法、热脉冲探针技术等水合物热导率测试方法的基本原理、应用现状及局限性。着重介绍了热脉冲探针-时域反射技术测试方法,该方法将热脉冲探针法与瞬态板热源法相结合,可有效克服和互补现有单一测量方法的不足,使测量结果更精确,对于今后水合物蓄冷技术和热导率测量方法的发展具有一定的现实意义。(图5,参47)Accurate measurement of the hydrate thermal conductivity is a key to the development and application of hydrates storage air-conditioning technology. Limited to hydrate thermal properties and metastability characteristics, hydrates feature larger difficulties and errors in thermal conductivity measurement than conventional materials, therefore, traditional methods cannot be directly used in testing the hydrate thermal conductivity. In this paper, the basic principles, application and limitations of several test methods like the transient hot-wire method, the transient plane source, the steady-state plate method and the heat pulse probe technology are presented. Especially, the heat pulse probe-time domain reflectometry test method is introduced, which combines the heat pulse probe and transient plate heat source, and can be effective supplement to single measurement method available now. This method can provide more accurate results, and will be significant for the future development of hydrate storage technology and thermal conductivity measurement. （5 Figures, 47 References）
