tem mode 中文意思是什麼
-
Many high - power microwave ( hpm ) sources utilize an azimuthally symmetric output mode such as the tm 01 circular waveguide or the coaxial tem mode as output mode. if radiated directly these azimuthally symmetric modes will generate a doughnut - shaped pattern, with a null on boresight
許多高功率微波源產生的微波模式都是圓波導軸對稱模式，由於其輸出埠的口徑場分佈具有圓對稱性，將導致軸向為零的環狀遠場方向圖。 -
It is paid attention to that the longitudinal component of electric field of the coaxial tm01 mode can be strong, differing from the tem mode in the conventional coaxial waveguide. so the coaxial tm01 mode can have much strong interaction with the electron beam
值得注意的是，與普通同軸結構tem波不同，同軸慢波結構tm01模式的縱向電場不為零，這是同軸返波振蕩器中的電子束能夠與它有強相互作用的重要原因。 -
Design and experiment study of coaxial fin - inserted tem - te11 mode converter
11模式轉換器的設計與實驗研究 -
We also propose two models to describe the propagation charcteristic of the focused hollow beam in 3d free space : one is the modified tem _ ( 01 ) mode doughnut beam model, the other is the width and narrow gaussian beam model
同時我們還提出了兩種聚焦中空光束的理論模型，一種是修改的tem _ （ 01 ）模式的doughnut光束模型，另一種是寬、窄高斯光束模型。 -
High quality znsxse1 - x thin film grown at the optimized temperature had the smoothest surface with lowest rms value of 1. 2 nm and tem cross - sectional micrograph showing a well defined columnar structure. the dependence of substrate temperature, deposition rate and alloy composition to the structure of the film was discussed in the thesis. the developed theory named " quasi - structure area mode " can successfully explain the film growth mechanism of polycrystalline znsxse1 - x thin films deposited on ito substrate by mbe
研究了採用mbe系統沉積zns _ xse _ （ 1 - x ）多晶薄膜的生長機理，分析了襯底溫度、沉積速率及薄膜組分對薄膜微結構的影響，提出的「類結構區域模型」可以較完整地解釋ito襯底上zns _ xse _ （ 1 - x ）多晶薄膜生長的機理。 -
The tm01 mode of the coaxial bwo has no cut - off frequency, which is similar to the tem mode in the conventional coaxial waveguide
這是因為同軸慢波結構的tm01模式有類似於tem的性質，沒有截止頻率。
