- The importance of the various solutions to one question - supported by the methods of the addition theorem of the cosine law
用余弦的加法定理不同的证明来说明一题多解的重要性 - In order to prove the arbitrary cardinal number alexandroff - urysohn addition theorem put forward in 1923 , the famous former soviet union topologist a . arhangel ' skii introduced network which is the important extension of base in 1959
1959年前苏联著名拓扑学家a arhangel ' skii为了证明1923年提出的任意基数的alexandroff - urysohn加法定理，引进了基概念的重要推广? ?网络( network ) 。 - Based on the extended boundary condition method and addition theorem of vector spherical functions , this paper study the light scattering problems of aggregate spheres from the angles of a single sphere , two - sphere system and multi - spheres system
本文基于扩展边界条件法及矢量球谐函数的加法定理，通过严格求解maxwell方程所得到的散射传输矩阵，对与入射波波长可比拟的群聚球形粒子的散射问题进行了研究。 - The ratma can calculate the electromagnetic scattering of multiple cylinders , and can be used in remote sensing . in chapter 2 simply derivation of the ratma is given by the addition theorem , and the general t matrix of single cylinder is deduced . the worked out examples show th e effectiveness of the ratma in the analysis of the scattering field of single cylinder or multiple cylinders
由于递推t矩阵法不仅可以计算多个柱体或不同形状柱体的散射，而且可计算遥感上三维物体的散射，在第二章中，利用加法定理，简要地推导了递推t矩阵法，并用解析法推出了单个圆柱体在各种情况下的t矩阵(此t矩阵对导体和介质圆柱体的散射场计算都适用) ，最后计算了单个导体圆柱和两个不同大小介质圆柱体的散射场。
