The principle of production of polymer mineral composite was analyzed. Property parameters and the procedure for producing PMC components were also given. Damping property and principle of vibration absorption of polymer mineral composite were also investigated. Reduced experiment was conducted for two jigs which are similar in structure only different in material that one made of PMC the other made of casting iron to test their dynamic characteristic.

Electroless NiP coating has stochastic nonlinear structure, which was in far from equilibrium and instability state. Fractal theory, an effective method for resolving nonlinear system, was introduced to describe the coating structure quantitatively. Disorker and self-similarity characteristics, which are the two basic features of fractal, were explained in this paper for the first time. The results show that amorphous NiP structure exhibits scale invariance and can be quantitatively characterized by fractal dimension. Based on the fractal principle, a two-dimensional computer simulation on electroless NiP deposition was carried out and it is in agreement with the experimental result. Finally, the fractal dynamics and process of atom growth were investigated. The results show that the atom deposition is reaction-limited growth process.
