摘要
Hamaker三个假设条件是用连续方法解离散问题的理论基础 .根据Hamaker三个假设条件 ,利用连续方法计算两个原子之间的相互作用力 ,发现作用力同经典的Lennard Jones势所反映的作用力不一致 .通过分析得出Hamaker均质材料假设条件仅适用于微观物质间距较大的范围以及数字密度随间距变化的结论 ;推导出数字密度随间距变化的表达式 ,修正了Hamaker提出的用连续方法计算微观物质间相互作用力的表达式 .最后对Hamaker常数进行分析 ,得出Hamaker常数本身就是随物质间距变化的结论 。
The three Hamaker hypotheses is the theoretical basis to resolve a discrete problem by continuance method. The atomic force, which is obtained by the continuance method on the basis of the Hamaker hypotheses, does not agree with the classical Lennard-Jons potential. The conclusions, that the Hamaker homogeneous hypothesis holds true only for two micro-substances separated far away, and that the digital density and the Hamaker constant vary with the distance, are obtained, followed by the forms of the digital density and the force between the micro-substances.
