絕對能隙 的英文怎麼說
中文拼音 [juéduìnéngxì]
絕對能隙
英文
absolute gap-
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。Based on signal from carbon fiber composite defects such as lamination, hole, looseners in ultrasonic testing, this paper performs wavelet packet transform on the ultrasonic signals to extract statistics of approximation coefficients and detail coefficients that contain a great part of signal energy as sample - features
摘要本文以碳纖維復合材料常見缺陷分層、孔隙、疏鬆的超聲波檢測缺陷信號為研究對象，對超聲波檢測信號進行小波包變換，提取包含信號絕大部分能量的近似系數波形特徵及細節系數的統計量作為樣本的特徵值。
