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.

The results showed that: 1 under the hydroponic culture established in this research, the experimental wheat plants grew well andperformed the typical architecture responses when exposed in Pi deprivation. Hemi-qantitative RT-PCR revealed that the transcriptional level of known P response gene changed dramatically; 2 In general the length of wheat root axis and the root/ shoot ratio arose when the Pi supply was deprived, however, the change models differed among different wheat genotypes. The investigation on their molecular basis would offer the useful clue for seeking high phosphorus efficiency protoplasma and gene resources of wheat.
