摘要
应用统计物理理论导出了弹性模量B(T,p)随压强p和温度T的变化关系式,并具体计算出Cu与Ar的弹性模量B(T,p).结果表明:压强较低时,Cu和Ar的弹性模量随压强的变化很小,然而当Cu和Ar的压强分别大于1012Pa和1011Pa时,B随p的增大而迅速增大,B随T的升高而减小.
The variation relations of elastical modulus with pressure and temperature have been concluded by using statistical physics. The modulus of Cu and Ar has been calculated. It shows that the modulus of Ar and Cu with pressure is small when the pressure changes. The modulus of Ar and Cu with pressure increase sharply when the pressure exceeds Pa and Pa respectively, and them decreases when temperature Increases.
