摘要
本文是Thomas-Fermi-Dirac-Cheng电子理论对共晶机理的阐述。提出了薄膜两组元之间的化学势差和电子密度差导致系统总能量改变的新思想,给出了研究稳定共晶态的最佳尺寸和能量的方法。
The criteria for stability of eutectics, solid solutions and precipitates are proposed. It is based on the Thomas-Fermi-Dirac model on the boundary conditions that electron densities and chemical potentials should be equal in either side of a composite film. The optimum condition for stabilizing the energy balance and the sizes of eutectics or precipitates is given.
