有知道angle of repose的么?
有没有网上的数据库提供各种物质的angle of repose
或着哪位讲讲如何测量angle of repose 我在wikipedia上提到一个叫shear cell的
instrument可用来测量，但是wiki上没写具体原理。

Just the angle between the ground and the cone edge of a pile of particles (
grains),
also called the internal friction angle. Commonly seen in the field of
sediment transport or granular flow
