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.

Human's skull is very solid and close. The physiologiers and the anatomists have used any means to divide it perfectly,but they have no such strength, later,someone invented suddenly a way ,that is put some seeds of plants in the skull that is to be dissected and provide them temperature and humidity to make them germinate. Once they germinate ,these seeds with terrible strength divided perfectly the skull that any mechanical power can't divide. The power of plants'seeds is so large.

Larches of different ages have different net photosynthetic rate: the photosynthetic capacity of the young ones are bigger than that of the old ones; the stand density do not affect the net photosynthetic rate obviously; as far as the different stand classes are concerned, the diurnal changes of net photosynthetic rate is closely related to the photosynthetic active radiation. For the different layers of the crowns, there are greater ecological factors (illumination intensity, temperature, humidity etc.) on the upper layers than on the lower layers: the CO2 concentration of the lower layers is greater than that of the upper layers, which is indeed an exception; the net photosynthetic rate on the upper layers of the crown is generally greater than that of the lower layers. It showed that the CO2 concentration is not a main factor in the natural changing range of the CO2 concentration. Different directions of the crown have different photosynthetic active radiation, which is generally like exposed to the sun﹥North﹥in the shade of crown. However, the changes of net photosynthetic rate are not quite the same, which is North﹥exposed to the sun﹥in the shade of crown.

不同年龄的兴安落叶松净光合速率不同，年龄小的个体光合能力高于年龄大的个体；群团密度与净光合速率没有显著的相关关系；而对不同分级木，净光合速率日进程变化规律与光合有效辐射有着密切的联系；林内树冠不同层次各生态因子有上层大于下层的趋势，而CO2浓度在下层的含量高于上层，净光合速率上层普遍大于下层，说明在林内自然CO2浓度变幅内，CO2浓度不是主要因子；兴安落叶松树冠不同方向的光合有效辐射不同，一般向阳﹥北向﹥背阴，而净光合速率变化有北向﹥向阳﹥背阴的趋势。

The USM is a kind of new electrical motor which develops in recent 20 years, it broke through the traditional concept of electrical motor. It didn"t have the electromagnetism winding and the magnetic circuit, and it didn"t uses the mutually electromagnetism to transform the energy, moreover, the volume of electrical motor is small, the weight is light, the transfer efficiency is high. For it was so small, so light, and so thin, it have begun to use on automobile. But the usage of superconductivity electrical motor is still in the experimental stage at present. The main reason is that the super conductivity material has not realized the high temperature, but with the development of technical, the possibly uses of superconductivity electrical motor in the big horsepower like automobile generator and on actuation electrical motor causes the electrical machinery to be smaller in volume, lighter in weight, and higher in efficiency.
