Examples
- In addition , the choice of the finite basis set enhances the calculation efficiency to some extent , especially for simulating the pes associated with many potential surfaces
另外，可以根据实际情况选择一定个数的基矢和格点，在一定程度上提高了计算效率，特别是在计算模拟具有多个势能面参与的光电子能谱时，其优越性是显而易见的。 - Study indicates that adapted ms potential surface is a kind of potential with concision form , coherent expression that can describe exactly the characteristic of system interaction . non - elastic scattering sections are sensitive to orientation of potential and strength of repulsive potential
最后的结论是：改进后的ms势能模型是一种形式比较简便、表达函数高度统一、能准确地描述系统的相互作用特征的势能形式。 - By analyzing the differentiae of the total cross sections ( tcs ) , the differential cross sections ( dcs ) , the partial wave cross sections ( pcs ) , the change patterns of the cross sections and the influence on the cross sections because of the var iations in the mass of systems and the relative kinetic energy of incoming atoms for symmetric isotopically substituted systems he , ne , ar , kr , xe - h2 , d2 , t2 have been obtained . in this paper , we use the tang - toennies potential model for the inertia gas atoms - h2 systems , the murrell - sorbie potential surface with five parameters for the molecules h2 , d2 , t2 . for the inertia gas atoms - d2 , t2 systems , we use the same potential surface with the inertia gas atoms - h2 systems
通过分析he 、 ne 、 ar 、 kr 、 xe ? h _ 2 、 d _ 2 、 t _ 2各碰撞体系在总截面、微分截面和分波截面等方面的差异，总结出在h _ 2分子的对称同位素替代情形下惰性气体原子与h _ 2分子体系碰撞截面的变化规律；通过比较he 、 ne 、 ar 、 kr 、 xe ? h _ 2 、 d _ 2 、 t _ 2各体系在碰撞总截面、微分截面、分波截面等方面的不同，详细讨论了同位素替代碰撞体系中体系约化质量及入射原子的相对碰撞能量的变化对碰撞截面的影响，得出了这种影响的规律性。 - This paper uses the method of tensor to proof the tenable condition of generalized plastic potential , discuss the mathematical essential of the associated and disassociated flow rule and the relation of the yield surface and plastic potential surface , reason the expression of plastic factor strictly . debate the limitation on drucker ' s postulate . subsequently , this paper gives the mathematical basis of constitutive theory involving the rotation of principal stress axes . so it is proved that the mathematical and mechanical foundation of the generalized plastic mechanic
