Aiming at the high-speed matching controlling problems between adaptive filters inplemented by FPGA and the high-speed AD converters, a high-speed sampling and adaptive filtering system was designedusing asynchronous FIFO. The dual channels AD converter AD9238-40 was used as input stage, two asynchronous FIFOs on-chip were used as high-speed buffer memory, and the sampling and adaptive filtering was controlled by FPGA. The asynchronous FIFO was customized and simulated on Quartus II, the sampling and adaptive filtering controller was designed and also simulated on Quartus II. The high-speed matching controlling of the dual channels AD converter AD9238-40 and the adaptive filter was implemented.

The main results of the investigation are as following:(1) Some important criteria for the design of multi-layer structure are acquired: the ratio of the layer thickness to the contact diameter should be controlled to a value about 0.8; increasing the number of the gradient layers and elasticity modulus of the top layer would benefit to the yield strength and the stress status at the interface.（2）By means of molecular dynamics simulations for a indentation and sliding process, it is discovered that dislocations of 45 direction to the surface occur in the surfaces layer, which is correspond to the direction of the plastic flows observed in the macroscopic continuous medium. The irreversible deformation caused by the dislocation and the atom piles at the surface are responsible for the irreversibility of the force response. They are also the main factors for the friction generation. The temperature and the indentation velocity have significant effects on the deformation behaviors of the material of the surface layer. The yield strength would increase obviously if the indentation velocity is greater than 10 m/s.（3）A method to evaluate the fracture toughness of coating by estimating the crack-density functionβof a Wicker''s indentation was proposed. Meanwhile a new surface treatment technology was developed using non-equilibrium plasma.（4）A MD-FE hybrid method and corresponding software was developed to analysis the tribological behaviors for multiplayer system.
