In this work, the parameters of embedded atom method for elements Al, Ce, Th and Yb have been determined by fitting the lattice constants, the cohesive energy, the monovacancy formation energy and the bulk modulus of elements.

• 本文运用欧阳义芳等人提出的普适分析型EAM理论(GAEAM(general analytic embedded atom method))，通过拟合纯元素的晶格常数、空位形成能、结合能和体积弹性模量等物理量，确定了铝(Al)、铈(Ce)、钍(Th)和镱(Yb)四个元素的嵌入原子参数。
