Selecting corresponding rolling force model, the paper make an experiment and studies on cold rolled paper-thin strip processing characteristics of sixteen-roll rolling machine based on cold-rolled theory aand forms corresponding rolling model, tension model and moment calculation model .And comes to a conclusion that distortion force and press utmost have a large effect on rolling force and paper-thin strip shape, primarily presenting paper-thin strip rolling subarea theory that rolling force decreases corresponding to the thick decrease of strip but increases rapidly when to a certain thick.

结合带钢冷轧基本理论，选用适当的轧制压力模型，针对十六辊轧机轧制极薄带钢时的工艺特点进行了实验和分析，建立了相应的张力模型及辊系传动力矩模型；并得出变形抗力及压靠对轧制极薄带钢时的轧制力和板形有很大的影响，初步提出了当带厚较大时，为保持板形良好，随着轧件厚度的减少，轧制压力相应降低，当轧制到一定厚度时，轧制压力随着带厚的减少急剧增加的极薄带轧制分区理论。

Effects of Coriolis force were analyzed with the three dimensional simulations and the following conclusions were drawn: The tangential component of Coriolis force induces cross stream secondary flow in the form of two-cell pattern,while the radial component of Coriolis force decelerates and accelerates the cent...

计算结果表明，切向哥氏力推动了通道截面内的双涡二次流，径向哥氏力则使得近侧壁流体加速和中心流体减速。换热计算结果从定性趋势上吻合公开文献中的实验现象，反映了旋转附加力的基本影响规律。

Comparing the experimental results with the results calculated using the OCIMF method, the reliability of using the OCIMF method is testified.Thirdly, the basic configuration plan of a ship undocking assisted by different number of tugs is given. The relationships among the gyroidal moment, gyroidal time and drag forces of tugs in the process of ship undocking are analyzed.

三、制定了不同数量拖轮协助船舶出坞时的基本布置形式，给出了不同拖轮协助船舶出坞时的拖轮布置示意图，并试验分析了船舶出坞回转力矩与回转时间和拖轮拖力之间关系，并确定了用于船舶出坞回转的拖轮拖力的余度大小。

It was showed that the growth speed of hypha, sclerotinia production and the pathogenicity of strains had little relation with host and geographical location. The ability of oxalic acid production of strains had positive relation with the pathogenicity. In order to study the nutrition aptness, 8 kinds of culture mediums were tested and the result showed that S.
