常見例句This is the waveshape specified in IEC 61643-1 Class 2. 這就是IEC61643-1等級2中所使用的波形。A single waveshape cannot be representative of a lightning strike and so one is not specified. 單一波形不能代表一個直擊雷,因而沒有作定義。The Class 2 test accomplishes this requirement.The waveshape is defined, not the charge Q. 等級2測試規(guī)定了這些要求,并對波形進行了定義,但沒對電荷Q進行定義。Chopped Waveshape of Electrooptic Gates and Shorten Pulses in Laser Amplification Process[J]. 引用該論文 孟紹賢;谷忠民;莽燕萍;唐賢忠;林尊琪.A deliberate change in waveshape, introduced either to counteract the expected effect of a subsequent transmission path or to render the signal less susceptible to noise. 有意引入的波形變化,以抵消其后傳輸通道的畸變作用或減小噪聲對信號的影響。MAIN OUTCOME MEASURES: Waveshape was observed through the use of storage oscillograph and corresponding data were recorded.Frictional force was determined and compared. 主要觀察指標:在存儲示波器上觀察波形并讀取數(shù)據(jù),測出各組摩擦力進行比較。 返回 waveshape
