Consequently the beam transmission problem is solved well. The general design curves of microwave plasma drift tube are developed by the theory and they can be used for development of the plasma microwave devices. Ion channel, as a important phenomenon in the interaction between electron beam and plasma, is first introduced into the study of PASOTRON, to replace the concept'plasma channel'used in general plasma microwave devices. A model is created to describe the channel performance. The channel is not stable, it is oscillatory and the oscillation frequency is larger than that of plasma.

作為電子束與等離子體相互作用的一個重要現(xiàn)象自拍偷拍第1页，本文首次將離子通道的概念引入到了PASOTRON的研究中肏女人逼12p，以區(qū)別常規(guī)的等離子體通道概念免费一看一级毛片视频，并通過建立的模型推出離子通道并非一穩(wěn)定規(guī)則的通道精品国产欧美在线观看不卡，而是具有振蕩特性，振蕩頻率高于等離子體頻率色无码夫妻在线，推出了當(dāng)滿足一定條件時束外可能沒有電子而成為純的離子通道亚洲欧美另类中文字幕，這種狀態(tài)對微波器件有重要的價值。

Well three in fact, Robins Stans No Tube set up was giving him some problems after the plane journey so he slapped a couple of tubes into his wheels instead.
