In the single crystal of C60 with a FCC structure,positron mainly appears outside the C60 molecule.The main annihilation space is the interspace between molecules.The calculated positron bulk lifetime in C60 is 352ps, which agrees with experiment value of 356ps in literature.In carbon nanotube bundles with different dimeters,as the diameter of carbon nanotubes increases,the main space where positron appears changes from the interspace of carbon tubes to the space inside carbon tubes,the radio between positron annihilation with valence eletrons and core eletrons becomes larger,the positron bulk lifetime in carbon nanotube increase rapidly first and come to be a constant at the end.The calculated positron lifetime of carbon nanotube with a dimeter of 0.8~1.6ns is 332~470ps,which agrees with the experiment value of 394ps.Positron annihilation has been studied in widly used compound semiconductors.
计算结果表明:在片层结构的石墨晶体中,正电子主要在石墨层间的空隙中湮没,计算出的石墨中的正电子寿命为208 pS,与文献中的实验结果215 ps符合很好;在金刚石单晶中,正电子主要在碳原子之间的空隙中存在并发生湮没,计算出的金刚石中的正电子寿命为115 ps,文献中的实验结果110 ps左右符合;在面心立方结构的C60晶体中,正电子主要在C60分子球壳内外侧及分子之间存在,C60球形分子中心正电子分布很少,正电子的湮没区域集中在C60分子之间的空隙区域,计算出的C60中的正电子寿命为352 ps与文献中的实验结果356ps相符合;对于不同管径碳米管束中的正电子分布,随着碳纳米管直径的增加,碳纳米管束中的正电子由主要在碳纳米管管间的区域出现转变为主要在碳纳米管管内中心的区域出现:碳纳米管束中的正电子与碳原子的价电子的湮没概率变得越来越大,与核心电子的湮没概率变得越来越小;碳纳米管束中正电子的湮没寿命先迅速增大,而后趋于一定值。

The reason why the model is based on Voronoi diagram and Delaunay triangulation is that one of the main factors of directional relationships is visible field of two objects, and the visible field is adjacent part of two object, so direction calculation of two objects may be limited in the adjacent field.
模型的建立之所以借助于Delaunay三角网和Voronoi图建立空间方向关系计算和描述模型,是因为决定两目标之间的空间方向关系的主要因素之一是这两个目标之间的可视区域,而可视区域恰好是它们的邻近区域,因而两目标的空间方向计算问题可以归结为目标间邻近区域内的问题。

Origin, developmental changes and homologies of the stage morphostructures were considered according to their location in three morphogenetic fields. The first, or central, field forms at the prodissoconch I stage. It can be inherited by prodissoconch II and nepioconch stages in one taxa, or PD-II, N and dissoconch stages in others. The second, or postero-dorsal, field appears at the N stage, and the third field, or antero-dorsal, at the D stage.

Analyzing and simulating of the deformation law of the ceramic downspout product after overcoming the shortage of powder material models in the software of MSC. MARC. It shows out the important effects of various factors and the shape of mandril during the process. And it is obvious that the shape of the top mandril has more effects on the process than the bottom.(3) Showing out the important effects of model figure on the flowing of powder and the forming of low-density fields from the analysis. After changing the top of the mandril into spherical shape, an improving model is putting out so that the distribution of stress and strain turns to be even and proper and that the flow rule of powder grains is better.(4) Calculating of the dimensional precision and the cutting ratio of the product and analyzing of the effects of such factors as rubber aging, loading process, mandril, friction etc. on the cutting ratio.
