提出晶体材料力学性能的热力学微观机理 ,推导并得到有关晶体材料力学性能的一些重要关系式。对金属单晶材料的弹性性能及本构关系进行了研究 ,得到的结果和数据与实际现象和试验结果相一致。

The mechanism and constitutive equation about mechanical properties of materials is one of the important factors in materials science research. Although many works have been done in these aspects, unfortunately, up to now, it is difficult to guide qualitatively and quantitatively the exploitation, processing and development of materials in theory. This paper proposes the thermodynamic micromechanism of mechanical properties for crystal materials, and deduces and obtains some important relationship equations about the mechanics properties of crystal materials. In this part, furthermore, the elasticity and its constitutive relationship for metallic single crystal materials are concretely researched. The results and data are well close to the practical phenomena and the experimental results.
