Question Surface Material Table

Hi, everybody!

I'm wondering what's the phisical meaning of REFLECTIVITY and EFFICENCY? I thought the reflectivity represents the fraction of incident electromagnetic power that is reflected at an interface, and the EFFICENCY is the transimission efficency. Then the larger the reflectivity, more photons will goes through the surface. However, the result is just the opposite. At the same time, however I change the value of EFFICIENCY, it seemed no change in the fraction of photons go through the surface.

When I set the reflectivity to 1, the result shows maximum, and it seems the reflectivity and transmission is calculated by the given RefractiveIndex of the two material. How can I tell the Geant4 to discard the caculated reflectivity and get the surface property?
