摘    要:用腔微扰法测定不同含水量的乙醇、丙三醇体系以及乙醇—乙酸体系的微波衰减曲线,探讨了混溶介质的微波衰减量与组成关系。结果表明,以氢键联结的缔合分子的偶极驰豫是介电损耗的主要原因。

关 键 词:醇-酸  醇-水  微波衰减  偶极驰豫

Abstract:The microwave attenuation curves have been measured by the cavity perturbation method for the systerrts alcohol-water glycerol-water and alcohol-acetic acid mixable media respectively. The relationship of the energy attenuation with the constitution of the medium had been discussed with the aid of NMR Raman and IR spectra. The results show that the dielectric loss is mainly attributed to the dipole relaxation of the larger polarized molecules which is in the form of the hydrogen-bonded association. The more number of the associative molecule lead to the more energy loss.
Keywords:Microwave attenuation  Diploe relaxation  hydrogen bond
