The blue shift could be associated with precipitation of xe gas bubbles . since the precipitation will change the defect morphology and reduce the sizes of each isolated defects , so to intensify the quantum size effects of nano - particles and induce the observed band gap broadening 10 ~ ( 17 ) cm ~ ( - 2 )样品峰位蓝移，是由于xe以气泡形式析出，改变了缺陷形态、使缺陷的分立尺寸减小，纳米粒子的量子尺寸效应变得明显，导致能隙展宽。

The studies on optical properties and irradiation effect of heavy ion implanted samples are very important from both theoretical and applied view points . in this work , the optical properties and defect structures in xe + - implanted ysz and ni + - implanted al2o3 were studied by using optical spectroscopy , tem , xps and trim 96 calculation . it was found that 1 ) a broad absorption band centered at 522 nm was observed in 1 1016 cm - 2 xe + - implanted ysz 离子注入是一种重要的表面改性技术， ysz ( yttria - stabilizedcubiczirconia )和- al _ 2o _ 3是两种性能优良的陶瓷，前者是目前发现的最抗辐照的绝缘体，而后者则是抗辐照最差的绝缘体材料之一，研究重离子注入对其光学性能的影响并以此研究辐照效应，有重要的理论意义和应用价值。
For liquid xe aerosol spray target , important lpp characteristics , such as laser - to - euv conversion efficiency , euv radiation absorption , debris production by target material erosion or deposition , are studied in detail , a 13 . 4nm conversion efficiency of 0 . 75 % into 2 % bandwidth and 2 steradian emission solid angle is achieved at 0 . 5mm laser - nozzle distance 在实验上，建成了一套高光谱分辨率和高灵敏度的软x射线脉冲辐射测量装置。测量了co _ 2 、 o _ 2 、 cf _ 4 、 kr和xe液体微滴喷射靶lpp光源在6 20nm波段的软x射线辐射光谱。
Thirdly , a new anisotropic potential energy surface is presented for the he - no system according to the ms potential model . the potential is not only quite agreement with the accurate esmsv potential for the system , but also has the same form and part parameters for the ms potentials of other rare gases ( ar , kr , xe ) with no molecule 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
