磁場失效 的英文怎麼說
中文拼音 [cíchǎngshīxiào]
磁場失效
英文
field failure-
Bose - einstein condensate ? a gas so cold that the atoms have lost their individual identity ? can act on sound like an expanding universe does on light, either by literally flying apart or by being manipulated using a magnetic field to give the same effect
一團玻色?愛因斯坦凝聚(一種冷到原子會喪失其個體性的氣體) ,可以像膨脹的宇宙對光的作用一樣,來對聲音作用,不管是令其飛散,或是用磁場來操縱,都可以得到同樣的效應。A bose - einstein condensate ? a gas so cold that the atoms have lost their individual identity ? can act on sound like an expanding universe does on light, either by literally flying apart or by being manipulated using a magnetic field to give the same effect
一團玻色?愛因斯坦凝聚(一種冷到原子會喪失其個體性的氣體) ,可以像膨脹的宇宙對光的作用一樣,來對聲音作用,不管是令其飛散,或是用磁場來操縱,都可以得到同樣的效應。Electron gun is the foremost parts of twt, it can produce electron beam with a certain shape and current, in order to guarantee the reliability and security of work, it ’ s design have to meet to the requirement not only of electric parameter, but also all kinds of subsidiary characteristics such as filament pyrogenation efficiency, warm up time, shape size, pole space capacitance and the ability to be able to bear the press and all kinds of rigorous run conditions such as high temperature, high humidity, low air pressure, strong vibration and great strike
由於行波管的大功率和高頻率等特性,目前還沒有任何其他的器件可以代替。行波管是應用高頻電磁場與電子注進行互作用的機理進行工作的,而電子槍是行波管中產生電子注並使它成型的基本部件,電子槍的結構設計決定了槍體自身必須具有良好的抗振可靠性,否則結構發生共振或振動位移過量,就會導致行波管的失效。因此對行波管電子槍的研究具有非常重要的意義。The finite element method ( fem ) has become an important means in modern engineering designs, which is used in many fields, such as structural stress analysis, deformational stiffness analysis, mechanic failure analysis, dynamic process analysis, heat analysis, electromagnetism filed analysis and so on
有限元素法已成為工程設計中不可或缺的重要技術手段,在大型結構作用力分析、變形分析、失效分析、動力學分析、傳熱分析、電磁場分析、流體流動分析等方面扮演著越來越重要的角色。An experimental system, based on the magnetic field theory and the ultrasonic vibrancy theory, was designed, and the experiments show that the average roughness value of the surface by compound - finishing is 0. 357 ? m lower than that by simple - finishing when the brush is used up in the traditional maf
以超聲振動理論和磁場理論為基礎設計了一套超聲磁粒復合研磨實驗系統,實驗證明,在單純磁粒研磨顯示磨粒失效的情況下,超聲磁粒復合研磨可以使表面粗糙度平均下降0 . 357 ? m 。分享友人
