    1959年前蘇聯(lián)著名拓?fù)鋵W(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(jìn)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(kuò)展邊界條件法及矢量球諧函數(shù)的加法定理,通過嚴(yán)格求解maxwell方程所得到的散射傳輸矩陣,對(duì)與入射波波長(zhǎng)可比擬的群聚球形粒子的散射問題進(jìn)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(hào)處理中的窗函數(shù),成功解決了在入射波為te波時(shí),用遞推t矩陣法計(jì)算電大尺寸物體或多個(gè)散射體時(shí),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(chǎng)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(diǎn)是要完成特殊函數(shù)在不同坐標(biāo)系間的變換,因此本文對(duì)graf加法公式的兩種表達(dá)及其適用范圍做了研究,另外對(duì)解決混合邊值問題的輔助函數(shù)法做了研究。
