摘要
在实验测定热膨胀系数基础上,计算原子振动的简谐系数和非简谐系数;利用Collins模型,以TiCu为例,求出原子作非简谐振动下的热力学函数,研究它的溶解度随温度的变化和非简谐振动对它们的影响.理论计算与实验结果基本一致.
Based on the measured coefficients of thermal expan- sion of Ti and TiCu, the harmo- nic coefficient and the first and second anharmonic ones of atom are calculated , Using a two-dimensional Collins model and taking alloy of TiCu as an example, the thermodynamic function in the case of anhar-monic vibration of atoms is established and the variation of solubility with temperature as well as anharmonic vibrational influrnce on them are also studied, caeactations in theot-ry are basically identical tp the ecperiment. reswets
