PCFK series of pairs of counter-reversible hammer crusher is a new crushing equipment, mainly by knock-on effects to broken materials, broken process in general is this: the material falling into the break in the world, imported high-speed rotation of the hammer impact face was against the entrance of the adjustable crusher tooth wear plate, for the first time broken, broken after the particles basically the same material evenly into the main break, the secondary primary crushing, crushing in the main chamber has been uniformly The material was re-kinetic energy particles from the hammer, high-speed rushed back inside the jagged cavity lining was broken, due to the special lining sawtooth-shaped structure.

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 show that the experimental results are in good agreement with the values of viscosity in a part of temperature range that has been reported, with the relative error of less than 2.5%; In the process of ascent and descent temperature, the irreversible phenomenon of the curve of viscosity versus temperature V presents interzone characteristic, and the break of viscosity at critical temperature reflects jump change of melt structural information; It is one to one correspondence between viscosity and atomic size, and this relation is consistent with the Hall-Petch formula in expression way.

The results show that TSN inhibits the delayed rectifying potassium current obviously when extracellularly applying 1×10〓g/ml TSN. The effect is dose-dependent and partial revisable. It develops slowly, and so does its recovering after washing. TSN also accelerates the inactivation of I〓, and this effect is much like that of Verapamil, Nifedipine and -Bay K 8644 on I〓 at NG108-15 cells. In addition, similar effects on I〓 are also observed when intracellularly applying TSN.

实验结果显示，细胞外施加1×10〓g/ml TSN明显降低I〓的幅度，作用呈量-效关系，部分可逆；TSN作用的出现和冲洗后的恢复过程都是缓慢的；TSN不但降低I〓的幅度而且还使之失活变快，这种效应同Verapamil、Nifedipine、-Bay K 8644对NG108-15细胞的I〓的作用相似；另外，将TSN施于细胞内，对I〓也有同胞外施加TSN相似的作用。
