Where l is the arc length opposite to αas a central angle ,r is the radius of the

如果半径为r的圆心角α所对弧的长为l，那么，角α的弧度数的绝对值是｜α｜＝l/r。

The central angle opposite to an arc of length equal to the radius is called an angle of 1 radian.

radian 长度等于半径长的弧所对的圆心角叫做1弧度的角。

A radian is the angle subtended by an arc of a circle whose length is just equal to the radius.

一弧度就是长度刚好等于半径的一段圆弧所对的圆心角。

Arc sine -- in radians !!!

反正弦 --以弧度为单位！！！

Arc tangent -- in radians !!!

反正切 --以弧度为单位！！！

Kelly maneuvered aggressively—jinking up and down, performing quarter rolls to veer around mesas, dropping into ravines and pulling up at the last instant to avoid a crash headlong into a wall.

凯丽有闯劲的机动着——闪动下降，围着台地表演四分之一弧度的滚动，下降到峡谷里，在最后一刻急停避免船头撞进峭壁。

The average standard deviation of the final transformation parameters was sub-voxel, sub-millimeter, and within 0.010 radians.

最后的变换参数的均方差值是亚像素、亚毫米级的，在0.010弧度以内的。

Do you want to have your board|with a lot of rocker or just a little?

你希望你的板弧度很大呢还是只要一点点？

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
