地震折射波的虚拟速度&临界角谱的原理与制作方法

On the base of experiments, this paper found the primary factor of caused atmospheric vertical refraction. A formula to calculate the angle of atmospheric vertical refraction is given.

以实验为基础，找出了导致大气竖直折光的主要因素，给出了大气竖直折射角计算的实用公式。

Geometric critical angle: refraction angle of axis of refracted sound beam being tangent to the internal wall at detection of cylindrical work pieces.

几何临界角：被反射的声音柱的轴心的反射角，这反射角和被探测的圆柱形加工件的内壁相切。

It is called the optical wedge , when the refraction angle of the refracting prisms is tiny.

当折射棱镜折射角很小时, 称之为光楔.
