multiple reflection

基本解释

We can extract respectively primary reflection and multiple reflection by adopting "separate bed" method.
在层状介质中，采用“隔离层”的办法，可以分离出一次反射波和多次反射波。
In contrast, methods used to depress regular interference, especially multiple reflection and surface wave are few.
但在压制多次波干扰和面波干扰方面，目前有效的方法并不多。
In contrast, an event is a multiple reflection if the intersection point of the rays has a reflection traveltime different from the observed traveltime.
从炮点入射的射线与从检波点出射的射线的交点形成的走时，若等于观测走时，可以判断此条射线是反射波；

Growth companies are often richly valued, with a high earning multiple, a reflection of investor belief that the company will expand further.
