If the angular velocity of a body changes, it is said to have an angular acceleration.

Here is an example of the usefulness of the concepts of angular impulse and angular momentum.

这有一个例子,可以说明角冲量和角动量概念的用途.

Hence a full subshell has zero angular momentum and is spherically symmetric.

于是,一个已经填满的支壳层的角动量为零,并且是球面对称的.

She was no longer as softly pleasing, more angular.

她已不再象从前那样温柔可爱了, 瘦削了一些.

In other words, the magnitude of the angular momentum is increased, its direction remaining the same.

换句话说, 即角动量的大小增加了, 但其方向不变.

在球转了五整圈之后,角速度是多少?

He has a more angular figure than his father.

他的体型比他的父亲更显得有棱角.

Find the angular deformation sustained with such loading.

求在这种载荷下出现的角变形.

Consequently angularities are apt to occur both below and above unconformities.

因此,交角往往出现在不整合面的上部或下部.

This principle can be extended to other angularity error evaluation.

文中的评定原理可扩展到其他倾斜度误差的评定.

The air flow will have some variation of angularity.

风的流向将有一定程度的变化.

Endurance is more important than pure speed, and as such, the stifles are only angulated.

耐力比单纯的速度更重要, 因此, 后膝关节的角度必须适中.

Steep, poorly angulated hindquarters are a serious fault.

过于倾斜和缺乏角度的后腿及臀部都是严重的缺点.

Ample bone, strong and flexible , moderately angulated at stifle and hock.

充足的骨量, 结实且柔韧, 后膝关节和飞节的角度恰当.

Balanced angulation fore and aft combined with powerful muscles and good condition produce smooth, efficient action.

前后角度平衡,配合上有力的肌肉,和良好的条件,形成了平顺 、 有效的动作.

Moderate angulation, with long shoulders sloping into the muscles of the back, clean at the withers.
