摘要
从热漫散射可以获得与聚合物材料中无序结构和热运动有关的电子密度涨落、纵声子群速和等温压缩率等参数.本文介绍和评述了热漫散射的理论及其应用.
Most of the parameters, such as electron density fluctuation, the group velocity of longitudinal phonons and the isothermal compressibility etc.which are related to the disorder and/or thermal motion in the polymer materials, can be obtained from the thermal diffuse scattering. The theory and application of the thermal diffuse scattering are introduced and described detailly in this review.
