MICROSCOPIC MECHANISM OF INFRARED RADIATION CHARACTERISTICS OF ELASTIC-SOLID MATERIALS

  • 摘要: 从原子晶格模型出发, 研究了原子振动频率及辐射随原子间距的变化规律; 探讨了固体材料弹性阶段的红外辐射特征、影响因素和所属形变范围, 并与弹性固体材料红外辐射场进行了对比分析. 发现本文模型揭示的红外辐射升温区和降温区与实验结果较为一致, 从而初步揭示了固体材料载荷初期红外辐射特征的微观机理.

     

    Abstract: 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.
