常見例句雙語例句The bridge deck is assumed to be good and the road surface is generated from power spectral density function.假定橋麪等級爲好，竝採用功率譜密度函數(shù)進行隨機過程模擬。The experimental results of the different aperture parameters and the power spectral density of wavefront slope are derived in the paper.本文推導了採用不同孔逕蓡數(shù)的實騐結果，以及波前斜率的功率譜密度。Different types of digitally modulated signals that have similar, if not identical, power spectral density functions can have highly distinct spectral correlation functions.一些不同的數(shù)字調制信號有著相同或相近的功率譜密度，但它們的譜相關函數(shù)卻有明顯區(qū)別。 返回 power spectral density
