When an xfs filesystem is created , the underlying block device is split into eight or more equally - sized linear regions 當創(chuàng)建xfs文件系統(tǒng)時,底層塊設備被分割成八個或更多個大小相等的線性區(qū)域( region ) 。
The comparison showed that : ( l ) farassat 1a formula is the simplest one and work well for the subsonic rotor . ( 2 ) both kirchhoff formula and k - fwh formula can predict the nonlinear noise generated by transonic rotor ; ( 3 ) when the surface is not positioned in the linear region , kirchhoff approach for rotating integration surface could lead to substantial error , but k - fwh formula can still work well 數(shù)值研究表明: farassat1a公式在預測線性噪聲方面簡單有效,適用于亞音速旋翼的噪聲預測; kirchhoff公式和k - fwh公式均能夠預測跨音速旋翼聲場,并且具有較高的精度;當聲源面位于流動非線性時, kirchhoff公式會導致很大的計算誤差,而k - fwh公式不存在這樣的問題。
