It can reflect the flame propagation speed and evaluate the explosion intension 計算出的分形維數(shù)是衡量湍流火焰?zhèn)鞑ニ俣纫约氨◤姸鹊挠行?shù)。
Like light waves , acoustic ( sound ) waves are characterized by a frequency , wavelength and propagation speed 聲波就和光波一樣,是以頻率、波長和傳播速度為其特徵。
At last , reflective crack ' s propagation speed of different pavement structural combination was analyzed too 最后運用paris公式對不同結(jié)構(gòu)組合的路面進(jìn)行了反射裂縫擴展速率的計算。
( 2 ) the influences of wave propagation speed uncertainty can be reduced when the measured current is decomposed using wavelet transform , and the high frequency ( 2 )通過對電流進(jìn)行小波變換并在高頻下進(jìn)行單支重構(gòu),可以減小行波波速不確定性對測距的影響。
A distract model has been firstly established to simulate the turbulent flame propagation speed for the dual fuel engine in this paper 本課題還首次建立了湍流火焰?zhèn)鞑シ中文P?,計算雙燃料發(fā)動機燃燒過程中湍流火焰速度,以評估發(fā)動機結(jié)構(gòu)參數(shù)和運轉(zhuǎn)參數(shù)對燃燒過程的影響。
