摘要: 近幾年來,由劉盛綱(1979,1981)發(fā)展的以回旋中心坐標(biāo)系中場的局部展開為基礎(chǔ)的電子回旋諧振受激輻射的動力學(xué)理論,已形成一個理論體系。本文簡要地闡述了建立回旋中心坐標(biāo)系的數(shù)學(xué)依據(jù)和物理解釋。文中通過回旋中心坐標(biāo)系法和波導(dǎo)軸坐標(biāo)系法,分別對單動量軸對稱電子注和圓波導(dǎo)中TEmn模式場的互作用進(jìn)行了計(jì)算,嚴(yán)格地導(dǎo)出了相同的色散方程。文中還指出了萬遂人(1995)文章中存在的若干問題。

Abstract: The kinetic theory based on the expansion of local field in the guiding center coordinate system, presented by Liu Shenggang (1979, 1981), has successfully developed into a theoretical system. A brief discussion about the mathematical background and physical explanation of setting up the guiding center coordinate system is given. By using the methods of the guiding center and waveguide coordinate systems respectively, the same dispersion equations for interaction between an electron beam and TEmn field in the circular waveguide are rigorously derived. -
