閃電脈沖 的英文怎麼說
中文拼音 [shǎndiànmàichōng]
閃電脈沖
英文
lightning impulse-
Because this device was intended as an electronic tranquilizer, it has blinking lights, pulsing tone, and heat outputs as well
由於這種裝置的目的是為電子鎮靜劑，它具有閃爍的燈光，脈沖聲音動，熱輸出等。The factors which influenced the process include the insulator ' s material, structure, the distribution of space electrical field, the way to deal with the surface, the characteristic of voltage waveform, pulse width etc. there are two kinds of theory for the vacuum surface flashover : secondary electron emission avalanche ( seea ) and electron triggered polarization relaxation ( etpr )
影響該過程的因素包括絕緣材料結構、空間電場分佈、表面處理方法、所加電壓特徵，脈沖寬度等。研究真空表面閃絡過程有兩類理論：二次電子發射崩潰（ seea ）和電子引發極化鬆弛（ etpr ） 。The shorter the interval between the two pulses of the current wave, the fewer strikes the varistors can endure. at the same time, the dc ljima changes fast - slowly - fast alone with the experiment continuing. microstructual disorder, such as variations in the height of the electrostatic potential at grain boundaries and electrode protrusions into the zinc oxide varistors, causes substantial temperature rise in a microscopic region around the defect and is the source for failure
雷電的多重閃擊對雷電過電壓保護器件的影響更加嚴重，本文首次採用不同間歇時間雙脈沖電流沖擊對氧化鋅電阻進行了多次試驗，試驗表明：氧化鋅電阻在雙脈沖電流沖擊下更容易出現老化破壞現象，間歇時間越短，電阻能耐受的沖擊次數越少；此外，直流u _ （ 1ma ）值隨沖擊次數的增加具有快一慢一快的下降過程。Surface flashover across the insulators in vacuum is the major limitation of the performance of the high power system, such as high power microwave tube, pulse power switch, high - energy linear accelerator, etc. flashover studies are of considerable importance in many applications. alumina ceramics are used widely in vacuum insulation system. the flashover and charging performance have been systematically investigated on alumina ceramics in vacuum under pulse voltage ( 0. 7 / 4 ^ 8 )
真空中絕緣子沿面閃絡現象是制約高功率微波管、脈沖功率開關、高能粒子加速器等系統性能的主要原因，這是因為真空中絕緣子在一個比自身及相同真空間隙擊穿電場低得多的電場下就發生了表面閃絡的緣故，研究真空中絕緣子沿面閃絡現象及其形成機理對于改善和提高系統性能有重要意義。2. the pre - flashover phenomena of alumina insulators in vacuum have been investigated. according to the experimental results, a reversed pre - flashover current was observed repetitively, which often occurs at the tail of pulse voltage close to zero ( sometimes after the applied pulse voltage )
首次發現了大量的、重復性的反向預閃絡現象，即在沖擊電壓波尾附近電壓幅值已經接近零、甚至在沖擊電壓作用完后（已沒有電壓）的情況下仍然存在試樣表面發光現象，同時伴有反向的電流脈沖。How do the strongest radio pulses from thunderstorms relate to lightning flashes
來自雷暴的最強無線電脈沖如何與閃電相關聯？Pulsed - flash gas - discharge lamp
脈沖閃光氣體放電燈Pulse corona and a new mechanism of the negative steppedleader in cloud - to - ground lightning discharge
脈沖電暈與地閃負先導梯級性機制模式探討External triggering uses a high voltage trigger pulse to create a thin ionized streamer between the anode and cathode within the lamp
外部觸發使用高壓觸發脈沖在閃光燈的陽極和陰極之間產生一個較稀薄的電離流Methods for the determination of the lightning impulse breakdown voltage of insulating liquids
