Finally the geometry model of the neutral atmosphere, the ionospheric plasma and geographic magnetic field and the earth radiation belt were given, and the universal 3D visualization scheme for the near-earth space environment element simulation was advance. 最终,分别给出了中性大气、电离层等离子体、地球基本磁场和地球辐射带的几何模型,提出了一种适合于近地空间环境要素仿真的通用三维可视化方案。
The basic principle of the method, the formula's derivation of the node force having prestrain in the neutral plane of the shell, the discussion of the effect of the hole in the element and the main features of a universal computer programme are introduced. 文中介绍了该分析方法的基本原理,推导了壳体中面内有初始应变时的相当结点力公式,讨论了壳单元开孔的计算方法并扼要介绍了计算机程序的功能。
Using high performance liquid chromatography, asphaltene and resin are respectively separated into three components, i. e. neutral, weak polar and polar. Furthermore, element composition, infra-red spectrum and hydrogen nuclear magnetic resonance are analysed for these three components. 作者以高效液相色谱法,将沥青质和胶质分离分析为中性、弱极性及极性三个组份,并对三个组份进行元素分析、红外光谱分析及氢谱核磁检测。
The locations of neutral points is varied along the lateral direction and calculated according to each strip element, so the three-dimensional asymmetric deformations process of the plate and strip is simulated more factually. 在B样条条元法中,通过分条计算中性点的位置,更真实地模拟了板带轧制时的三维不均匀变形。
