Twt has the characters of high plus , wide frequency , longevity and high reliability , so twt is the core apparatus of communication , radar , electron antagonizing , ground station and microwave pyrogenation system , and has most important role in modern high - tech war 大功率行波管具有大功率、高增益、寬頻帶和長壽命等特點,廣泛地應(yīng)用于雷達、電子對抗和通訊等國防重點工程.被譽為武器裝備的“心臟” 。
2 . considering current equipments and requirements for db935 , the technics standard were made sure , including the cathode weld and carbonization , manufacture of the pyrogenation graphite grids , surface treatment , assembly and the exhaust after a lot of research and improvement 2 、根據(jù)公司現(xiàn)有的裝備條件和db935的要求,通過不斷探索和改進,確定了陰極焊接及碳化、熱解石墨柵極制造和表面處理、整管裝配和排氣等工藝規(guī)范。
A new type heat carrier pyrogenation was designed independently to solve the heating problems of the heat carrier in the course of bio - oil preparation with the design theories and methods of the fuel and gas boiler and pneumatic conveying combined , which laid a foundation for the project popularization and actual application 摘要結(jié)合燃油燃氣鍋爐和氣力輸送的設(shè)計理論與方法,自行設(shè)計制造一種新型的熱載體加熱裝置,以解決生物燃油制備過程中熱載體的加熱問題,為該項技術(shù)的推廣應(yīng)用奠定基礎(chǔ)。
As for materials for faradaic pseudocapacitor , we mainly studied metal oxide . the paper prepared ferric oxide by sol - gel method , decomposition product of potassium permanganate and cobalt oxide by pyrogenation way , nano - nickel oxide by sol - gel and pyrogenation method and manganese oxide by different ways 本文用溶膠?凝膠法制行備三氧化二鐵;熱分解法制備了高錳酸鉀分解產(chǎn)物和氧化鈷;分別用溶膠?凝膠法和熱分解法制備了納米氧化鎳;還用不同的方法制備了二氧化錳。
Analyze 1000hpa stream field evolvement chart , a southwest - northeast combine strap was forming in liaoning province by southwest air current and northwest air current . level combine induce the combine strap cyclone bend , whorl degree intension increase . boundary layer friction combine bring to ascend and come into being small measure cumulus convection pyrogenation 高低空急流的耦合是此次強對流爆發(fā)的重要觸發(fā)機制,高低空急流在耦合的過程中, 300hpa高空急流強度超過50m s , 850hpa低空急流強度超過20m s ,而且低空急流與高空急流剛好在高空急流出口區(qū)的位置上相交,對強對流爆發(fā)有利。
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 由于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(yīng)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(chǎn)生電子注并使它成型的基本部件,電子槍的結(jié)構(gòu)設(shè)計決定了槍體自身必須具有良好的抗振可靠性,否則結(jié)構(gòu)發(fā)生共振或振動位移過量,就會導(dǎo)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。
