RESULTS: SEM results showed that the fiber morphology of P(50/50) 6% nanofibers membrance was better and more uniform diameter distribution. Mechanic test indicated nanofibers membrance of P(50/50) had longer breaking elongation but smaller breaking stress than nanofibers membrance of P(75/25). Hydrophilicity of P(75/25) fibers was better. MTT results proved that 6% and 8% P(50/50) nanofibers could enhance the adhesion and proliferation of endothelial cells on the surface of materials, and the cells had the best spreading and attachment on the nanofibers.

Based on a lot of experiments, it shows the distinct error between classical theory curve which express the relation of cell diameter, cell density and foam tensile strength , tensibility tensile product and re-spring degree and experiment curve. It also can＇t explain the relation of hole degree , area of cell wall with above four mechanics parameter. But the sub-cluster scale theory was demonstrated successfully to explain the relation of cell structure and foam mechanics property on different mold temperature, mold pressure, mold period and different chemical blowing agent, blowing activator content.

通过大量的实验结果理论分析表明：以往的经典理论存在着很多不足之处，它不能有效地解释孔径、泡孔密度与抗拉强度、断裂伸长率、断裂功、及回弹率之间的理论曲线与实验曲线之间的偏差，也不能解释空隙度、泡孔壁厚与上面四者之间的关系，而群子标度理论则成功地论证了在不同模压温度、模压压力、模压时间及不同用量发泡剂、发泡促进剂条件下泡体力学性能与结构之间的相关性。

The earthquake produced not only the surface ruptures along the Yingxiu-Beichuan Fault and Guanxian-Jiangyou Fault,but also surface rupture,highway s pavement arching,sand-boils and waterspouts in various degrees in the areas such as Shifang and Mianzhu of the Chengdu plain.

此次地震不但使NE向的映秀-北川断裂和灌县-江油断裂发生了地表破裂，而且，在成都平原区的什邡、绵竹等地也出现了不同程度的地表裂缝、公路拱曲以及带状的喷砂冒水现象。

Electron microscope of the scheme of chart of X ray diffraction that analyses composite material, transmission and photograph of scanning electron microscope make clear: OMMT basically is with coming off condition disperses in PLA matrix, form in order to come off model give priority to, the accept rice that at the same time existence inserts a structure composite material, the affiliation of OMMT makes the drawing section of composite material ruptures to tenacity by brittleness change.
