From the existing theory of the random medium model, every single local maximum point of a continuous random medium as the center point of each cave distribution area was taken, the two model characteristic quantities namely the local radius R and the local density p were introduced, simulated all sorts of different random cave medium models by the.

The boundary layer effect of the powder injection molding filling flow process was studied through local density measurement and SEM.

In this paper, the method in which a local density of state of a system can be obtained through the exact solution for the Green s function is extended to the case with non-orthonormal hots, and the applicable range of this method is extended.
