本文从麦克斯韦电磁理论出发，理论上分析了微波与物质相互作用机理，指出介质吸收微波源于介质对微波的电导损耗和极化损耗，高温下，电导损耗将占主要地位．利用微波加热物质，物质的损耗有一定的限制，对干2．45GHz的微波，物质电导率应在1Ω-1cm－1以下，根据现有的无机非金属材料的电导率数据，对某些无机非金属材料的微波加热特性进行了简单的评估；在一些简单的假设下，对微波加热样品时，样品内部温度分布情况作了简要描述，对微波场中非均匀固体的行为进行了简单的分析和预测．
Based on Maxwell’s electromagnetism theory, this paper theoretically analyzes the interaction mechanism between microwave and matter, and points out that the medium absorbs microwave from the medium to the conduction and polarization losses of the microwave. Under high temperature, the conduction loss will dominate. The use of microwave heating material, material loss has certain restrictions on the dry 2.45GHz microwave, the material conductivity should be below 1Ω-1cm-1, based on the available inorganic non-metallic materials conductivity data for some inorganic The microwave heating characteristics of non-metallic materials are briefly evaluated. Under some simple assumptions, the temperature distribution inside the sample is briefly described when the sample is heated by microwaves. The behavior of the non-uniform solid in the microwave field is briefly analyzed And forecast.
