So it's past the critical angle; the angle is smaller.

它超过了临界角;,角度变小。

In addition, critical Angle method is introduced for automatic focusing.

同时还采用了全反射临界角法进行自动聚焦。

but remember, we set it at the critical angle, so that cotangent alpha is 2 mu.

,但是记住，摆放的恰是临界角，所以cotα等于2μ

At all angles less than the critical Angle, both reflection and refraction occur.

对于所有小于临界角的入射角，则既发生反射，又发生折射。

In dynamic analysis of complicated structure, critical Angle of seismic wave is corresponding to critical response of structure.

对于复杂结构，在动力分析中地震波的最不利输入方向对应着结构的最不利反应。
