Angle of reflection [光] 反射角 ; 折射角 ; 偏极角
critical angle of reflection 临界光反射角
Because of the Angle of reflection, the second rainbow appears with the opposite colour scheme to the first.
由于反射的角度，第二层虹的色彩搭配显得同第一层有一点相反。
It is accurate to within 0.03mm. The same sensor is used on a boat to shine a beam off the tiller bar, using the reflection to measure the Angle of the rudder.
这个感应器非常精确在0.03毫米内，同样的感应器也用在船只上去投射舵柄连接杆发出的电波，利用反射去计算舵的角度。
If the object is canted at a greater Angle, there is no reflection of the ultrasonic pulses.
如果该对象是在一个更大的角度斜，没有任何的超声波脉冲反射。
