loading noise造句
例句與造句
- In addition , the error comes from the arithmetic discussed above is analyzed and an error criterion which made this arithmetic suitable for forecasting the loading noise in engineering is given based on the calculational results
并結(jié)合實(shí)際算例,對(duì)本文算法中所產(chǎn)生的誤差作了比較分析,總結(jié)出了一個(gè)誤差判據(jù)。 - The theoretical deduction in chapter 3 shows that the shape of load distribution used in the arithmetic is a decisive fact of the error margin size , the more the adoptive shape looks like the actual case , the smaller the error margin will be , therefore the tilt parabola shape can instead of the actual shape of load distribution in the permissible error margin when we predicting constant loading noise caused by the tail rotor of helicopter
在第三章中通過(guò)理論推導(dǎo)和計(jì)算比較發(fā)現(xiàn),在預(yù)測(cè)直升機(jī)尾槳定常載荷噪聲時(shí),其誤差大小取決于算法中槳葉弦向載荷分布的數(shù)學(xué)描述與實(shí)際弦向載荷分布的吻合程度,而選取一種與實(shí)際弦向載荷分布較為相似的斜拋物線形來(lái)預(yù)測(cè)噪聲所導(dǎo)致的誤差是很小的。 - In chapter 2 , the fluctuate equation of monopoly sound field and dipole sound field is deduced detailedly , the root of this equation is given . analytical models is developed to investigate the noise of helicopter tail rotor , that is to say : the thickness noise and the loading noise is determined by a monopole source and a dipole source respectively
在第二章中對(duì)單極子聲場(chǎng)和偶極子聲場(chǎng)的波動(dòng)方程及其求解做了詳細(xì)的理論推導(dǎo),建立了直升機(jī)尾槳的厚度噪聲和載荷噪聲計(jì)算模型,即可分別用單極子和偶極子聲源描述厚度噪聲和載荷噪聲。 - It's difficult to find loading noise in a sentence. 用loading noise造句挺難的
