第三，根据ms势模型给出了he - no系统的各向异性势能面，该势能面不仅与he - no较准确的势能面esmsv符合较好，而且与其它惰性气体原子( ar 、 kr 、 xe )与no分子的ms势具有相同的形式和部分势能参数。 - 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。 - Therefore the profit expression with these two variablesharvesting efforts e and its mapping equilibrium xe could be translated into an expression which included only one variantthe positive equilibrium xe so that the problem is converted into the one of seeking stationary points in the range we requied by calculus essential principal . this equaled to solve a n - dimension linear equation group and we could easily analyse every possible situation of the solutions
由于此时系统的正平衡点存在且唯一，可从系统模型中求出正平衡点与相应捕获努力量之间的关系式，从而可将包含捕获努力量e和正平衡点x _ e两个未知量的利润表达式转化为只含正平衡点x _ e的表达式 - When compared with kds301 ( lexa + ) , xe ( lexa - ) cells showed quite similar levels of survival curve to y - irradiation and mmc , indicating lexa gene had no effect on radiation resistance of deinococcus radiodurans . deinococcus radiodurans " lexa had no revelance with its extremely radioresistance . the recombinant plasmid pza172 was constructed by cloning the lexa gene of deinococcus radiodurans into the vector plasmid puc19 in the downstream of lacz promoter
对lexa基因突变体xe的研究表明，其辐射抗性与lexa基因野生型的抗辐射菌kd8301相近，存活曲线上均显示有一个宽大的肩区，结果发现lexa基因的突变并没有改变抗辐射菌的独特抗性，说明lexa基因与辐射抗性无关。 - It's difficult to find xe in a sentence. 用xe造句挺难的
- Finally , we rebuild a soft x - ray reflectometer in 8 - 30nm region by replacing its metal target with low - debris kr and xe aerosol spray targets . reflectivity of soft x - ray multilayer mirrors are measured by the new reflectometer , and the results show the accuracy is about 2 % %
