MICROSCOPIC MECHANISM OF INFRARED RADIATION CHARACTERISTICS OF ELASTIC-SOLID MATERIALS

Based on the model of atom lattice, the variationof atom vibration frequency and radiation against the distancebetween atoms is studied in this paper. The infraredradiation characteristics and influencing factors and the deformation rangeare analysed and discussed in the elastic stage of the solidmaterials. The theoretical results are compared with the infrared radiation fields of the elastic-solid materialsin the experiments. The results in those infrared increased temperature zonesand infrared decreased temperature zones agree well with the test results, therefore, the microscopicmechanism of the infrared radiation characteristics for solid materials inthe process of primary loading in room-temperature is confirmed.
