从表面判断

To calculate numerically the radiation of a enclosure within a heteromorphosis cavity, attention was focused on: how to decide the visibility between two surfaces, how to improve the old method of configuration factor computation, how to approximately and efficiently decide the radiation resource of directional, spectral radiation in cavity.

讨论了解决异型封闭腔辐射几何学问题的几种方法：异型封闭腔内，表面间可见性的判断方法；优化异型封闭腔角系数计算的方法；确定异型封闭腔内定向辐射的壁面辐射源的方法。计算了两种结构喷管封闭腔内的角系数，并从角系数的互换性和完整性定理验证了方法的正确性和有效性，为异型封闭腔的辐射计算解决了几何问

Their adsorption rate on the molecular sieve catalysts surface and the stability of their carbonium ions were then obtained based on the molecular simulation on these molecules from their dipole moment, 2-dimensional electrostatic potential energy contours and 3-dimensional electrostatic potential energy isosurface.

采用半经验的AM1量子化学计算方法和静态理论，分别考察了噻吩、 3 甲基噻吩和 2 ，5 二甲基噻吩分子结构特性的不同，从偶极矩、各自垂直于芳香环平面的二维电势能分布曲线和整个分子周围三维电势能分布情况等方面分析了它们在分子筛催化剂表面吸附速度的快慢和生成正碳离子稳定性的高低，进一步比较了噻吩及其衍生物所生成的正碳离子进一步反应的能量变化，从而可判断噻吩及其衍生物裂化脱硫速度的快慢，噻吩及其衍生物裂化脱硫的速度由大到小分别为：2 ，5 二甲基噻吩、 3 甲基噻吩、噻吩。
