血管緊張素轉換酶基因多態性與高血壓病早期腔隙性腦梗死的關系A convergence acceleration technique, boundary element method ( bem ), spectrum of two - dimension solutions ( s2ds ) method are used separately in solving dyadic green function of the three domain. next, waveguide narrow - wall slots array ' s is introduced in this paper
對外部空間，與縫隙腔體區域一樣認為場量與z無關，對所有場量做z方向的fourier變換，得到譜域上的一系列去耦合的二維方程。The basic principle, main properties, typical parameters, technical characteristics and general situation of klystron are introduced. the electron beam prebunching in the modulated cavity and shift tube of relativistic klystron amplifer ( rka ) is studied analytically, a self - consistent equation of radiation generated by the prebunched electron beam in the radiation cavity is derived using the field method of particle ? wave interaction instead of the electrical circuit method, and in terms of it, the gain in the linear regime calculated, a field analysis method is proposed. the theory analysis shows that the characteristic parameters, such as resonance frequency, real part of gap - impedance, external quality fadtor in all kinds of klystron output circuits including single - beam, multi - beam, single - gap, multi - gap, single - beammulti - gap, multi - beam multi - gap klystron output circuit, can be calculated by the field analysis method
本文系統的介紹了速調管的工作原理、主要特點、發展概況、主要性能指標和技術特點，解析的研究了電子束在相對論速調管放大器的調制腔和漂移管中的預群聚;用粒子波互作用的場方法導出了在輻射腔中預群聚電子束產生輻射的自洽方程，同時對線性區的增益進行了計算。理論分析表明，場分析法可用於計算單注單間隙、多注多間隙、單注多間隙和多注多間隙速調管輸出迴路的諧振頻率、間隙阻抗實部和外觀品質因數等特性參數。Under the cylindrical coordinate, the transit - time effect of the radial gap in the resonance cavity of rtto is studied by hydrodynamic theory. the equation describing the interaction between the electron beam and the high frequency field is obtained
在柱坐標系統中，我們用流體理論方法分析了rtto諧振腔間隙的渡越時間效應，得到了在有限渡越角情況下電子束與高頻場相互作用的方程。Based on this arithmetic, the high frequency characteristics of five - cavity with open boundary is calculated by the code written in fortran language. then the transit effect of five modes of five - cavity with open boundary is also calculated using code mathcad and matlab. the results show that the working mode of five - cavity transit tube oscillator is 3 / 6 mode, and the analysis of the theory are in good agreement with the simulation results
根據從基於四腔渡越時間效應的自調制出發，經過一段飄移，然後再採用雙間隙提取腔邊耦合輸出高功率微波的思路，採用粒子模擬方法優化設計出一種峰值功率為1 . 5gw ，頻率為9 . 3ghz的六腔渡越輻射振蕩器，並研究了它的一系列工作特性。分享友人
