查询词典 rotation direction

Not only is the Earth's rotation too weak to affect the direction of water flowing in a drain, tests you can easily perform in a few washrooms will show that water whirlpools both ways depending on the sink's structure, not the hemisphere.

其实，地球自转的作用很微弱，因此难以影响水流动的方向。你可以在一些盥洗室中轻易地验证这一点，无论是逆时针还是顺时针，水流旋涡的方向取决于水槽的结构，而非南北半球。

Firstly, saltating sand grains in various height layers mostly rotate clockwise; the rate of counterclockwise rotation changes from 16.7 to 33.3% for three different friction wind speed (u*= 0.67, 0.83, and 0.87 m/s). However, their mean rotational speeds were not significantly different, irrespective of whether the grains rotated clockwise or counterclockwise. The mean counterclockwise rotational speeds of sand grains for friction wind speed u*= 0.67, 0.83, and 0.87 m/s were 427, 519, and 604 rev/s, versus 429, 522, and 609 rev/s, respectively, in the clockwise direction.

首先，风沙流中各高度层内跃移沙粒旋转均以顺时针方向为主，逆时针方向旋转的沙粒数仅占总数的16.7-29.5%，但是无论逆时针还是顺时针旋转的沙粒，它们的平均旋转速度几乎没有差别(如u*＝0.67 m/s时，分别为427 rev/s和429 rev/s；u*＝0.83 m/s，分别为519 rev/s和522 rev/s；u*＝0.87 m/s，分别为604 rev/s和609 rev/s)；不同摩阻风速条件下各高度层内沙粒的旋转速度均服从Lorentzian分布。

This paper measured the transmittance spectrum of Sr_3NbGa_3Si_2O_(14),a new kind of piezoelectric single crystal,from ultra-violet to visible wavelength and studied its optical activity by a novel method—measuring the transmittance spectra in Z-direction between parallel polarisers. And the rotation dispersion was fitted.

本文测定了紫外、可见光区新型压电晶体—Sr3NbGa3Si2O14的透过率，并利用一种新方法即通过测量晶体在平行偏振系统中的透过率谱研究了其旋光性，且拟合出旋光色散曲线。
