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證明來說明一題多解的重要性
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年前蘇聯(lián)著名拓撲學(xué)家a arhangel ' skii為了證明1923年提出的任意基數(shù)的alexandroff - urysohn加法定理,引進了基概念的重要推廣? ?網(wǎng)絡(luò)( 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 本文基于擴展邊界條件法及矢量球諧函數(shù)的加法定理,通過嚴格求解maxwell方程所得到的散射傳輸矩陣,對與入射波波長可比擬的群聚球形粒子的散射問題進行了研究。
In chapter 4 windowed function of data signal processing is introduced and applied to addition theorem , which succeeds in solving the difficult problem : it has a bad result when recursive t - matrix is applied to calculate the wave scattering of electrically large objects and multiple objects in the excitation of te wave 在第四章中引入數(shù)字信號處理中的窗函數(shù),成功解決了在入射波為te波時,用遞推t矩陣法計算電大尺寸物體或多個散射體時,精度不高的問題。
Since the antiplane scattering problems of local sites could be divided into two kinds : interior and exterior problems , main points to solve the problems are graf ' s addition theorem . so two expressions and suitable range of the graf ' s addition theorem are studied hi the paper . moreover , an auxiliary function method for mixed boundary - value problems are also discussed in this paper 由于典型局部場地彈性波出平面散射問題可以分為內(nèi)域型和外域型兩大類,求解這些問題的要點是要完成特殊函數(shù)在不同坐標系間的變換,因此本文對graf加法公式的兩種表達及其適用范圍做了研究,另外對解決混合邊值問題的輔助函數(shù)法做了研究。
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 由于遞推t矩陣法不僅可以計算多個柱體或不同形狀柱體的散射,而且可計算遙感上三維物體的散射,在第二章中,利用加法定理,簡要地推導(dǎo)了遞推t矩陣法,并用解析法推出了單個圓柱體在各種情況下的t矩陣(此t矩陣對導(dǎo)體和介質(zhì)圓柱體的散射場計算都適用) ,最后計算了單個導(dǎo)體圓柱和兩個不同大小介質(zhì)圓柱體的散射場。
