Based on the self - consistent nonlinear theory of complex cavity gyrotron with gradual transition, a simulation code of self - consistent nonlinear beam - wave interaction has been made, in which the multiple modes interaction with an electron beam and the mode coupling are taken into account. the interaction between the electron beam and hsn - h521 rf field for third - harmonic gyrotron is simulated. the influences of the thickness and the velocity spread and the velocity ratio of the electron beam and the fluctuation of the magnetic field and the technologic errors of complex cavity on the multi - modes interaction with an electron beam are analyzed
二、在漸變復合腔迴旋管多模自洽非線性理論的基礎上，編制了高次諧波漸變復合腔迴旋管多模注?波互作用自洽非線性模擬軟體，並對8mm波段三次諧波漸變結構復合腔迴旋管的注? ?波互作用進行了大量的自洽非線性數值模擬計算與研究，進而分析了電子注的厚度、速度零散、速度比值、磁場波動、腔體尺寸的加工誤差等等多種因素對互作用效率的影響。 -
As for the main components of this pattern, it includes the following factors : openness and nonequilibrium state are the prior condition ; fluctuation is the original causation ; competition and synergetic effects are the driving force ; gradual change and violent change are the developmental approach ; innovation is the starting point and the destination of the curriculum development
開放和非平衡是課程發展的前提條件；漲落是課程發展的起因；競爭和協同是課程發展的動力；漸變和突變是課程發展的途徑；創新是課程發展的出發點和歸宿。
