finite width造句
例句與造句
- realistic signals are made by summing sine waves of lots of frequencies, so that after some finite number of wavelengths they interfere destructively and you get a signal of finite width and duration
現(xiàn)實(shí)中的信號(hào)由各種頻率的正弦波組成，因此，在有限的波長(zhǎng)數(shù)后，它們會(huì)干涉相消，你就得到一個(gè)有限寬度和有限延續(xù)的信號(hào)。 - kung k . y ., hsu, c . h ., chen p . c ., lin, j . r ., 2004, effects of surface roughness on dynamic squeeze behavior of partial journal bearings with finite width, 5th wseas international conference on applied mathematics, miami, florida

鑒于工程中廣泛使用有限寬軸承，而對(duì)于這種軸承的油膜力的計(jì)算，采用數(shù)值方法計(jì)算工作量很大，而解析法又無(wú)能為力的情況，本文引入了一種適用于工程精度要求的平均本征值法。 - second the model of array was considered to have elements of finite width and infinitely large elevation dimension . this model ignore the effect of elevation on beam focusing . this paper study on phased array which was considered to have elements of finite width and finite elevation dimension, the influences of transducer parameters on focusing effect is analy / ed, including the number of elements ( n ), interelement spacing ( d ), elevation dimension ( l ), width dimension ( )
這種方法雖然計(jì)算方便，但實(shí)際很難實(shí)現(xiàn)，真正的振元總是有一定的尺寸，這種方法忽略了陣元的尺寸對(duì)聚焦效果的影響，后來(lái)，另一種線性陣的模型被提出，即認(rèn)為單個(gè)陣元具有一定寬度a，長(zhǎng)度l為無(wú)限長(zhǎng)，或者說(shuō)a遠(yuǎn)小于l，這種模型忽略了陣元長(zhǎng)度l對(duì)聲波聚焦效果的影響。 - It's difficult to find finite width in a sentence. 用finite width造句挺難的

實(shí)驗(yàn)結(jié)果表明，氣道不同，條紋的變化方向不同，但同一氣道在不同的流量下，條紋的變化方向是一致的；不同形狀的氣道對(duì)流量的敏感程度不同，對(duì)氣體旋流的擴(kuò)散作用影響也有很大的差異；用無(wú)限寬條紋法得到的圖像直觀，靈敏度大，易于做定性的分析對(duì)比，而有限寬條紋法可以進(jìn)行流體在運(yùn)動(dòng)方向的判別，更有利于詳細(xì)的分析研究。
