The possibility for preparing nanocrystalline materials by jet-electrodeposition technique is also analyzed. Corresponding the research in the article, a set of unsubmerged single circular jets equipment was designed. In chapter 2, jet-electrodeposition was carried out both under direct current condition and pulse current condition. A series of samples for nanocrystalline nickel coating were prepared under different deposition parameters.

The results indicate that in the synchronizing condition the MRF is unyielded, every point of MRF in the flow field has the same angular velocity. Under the slipping condition, with the increase of magnetic field or the decrease of slip speed, MRF may transfer from whole yield to partial yield. When the MRF wholly yields, the angular velocity of MRF increases nonlinearly with its radius, the non-linear distribution becomes more obvious as the magnetic intensity in the working gap increases. When the MRF partially yields, the yield region expands with the decrease of magnetic intensity or the increase of slip speed and the unyield region always reaches the driven rotor. The transfer torque of MRTD increases with the increase of the external magnetic field, but the transfer torque maintains a constant value approximately with the variation of slip speed at the same magnetic intensity.

研究结果表明，在同步工况下，传动装置流场中磁流变液未屈服，各点角速度相同；在滑差工况下，随外加磁场的增大和滑差转速的减小，磁流变液逐渐从完全屈服向部分屈服转变；磁流变液完全屈服时，磁流变液角速度随半径呈非线性增加，工作间隙中磁场越强，流场的非线性分布越明显；磁流变液部分屈服时屈服区域随外加磁场的增大而减小，随滑差转速的增大而增大，未屈服区与主动转子相连；稳态下磁流变传动装置传递的转矩随外加磁场的增加而近似呈线性增大，但在相同外加磁场下，传递转矩基本不随滑差转速改变而改变，表现出良好的恒转矩特性。

Mark J1C at theintersection of the two lines.It is necessary to use a new standard specimen to do J-integral test. The dimension of standard specimen is 10 mnx20 nsnxiOO mm .The results from this specimen are satisfied with the condition of validness of J-integral as well as the condition of plane-strain. The reason is explained.

Alai demonstrates the vicissitude of TUSI system to readers with poetic words. Established in the profound national culture the work is full of philosophic reflecting about ethnical culture and deep expounding about religious culture. It brings forth the survival condition of every class in TUSI age and the complicated idea of religious culture of void and silent thought hiding behind the survival condition. The work is filled with deep and paradoxical ideas.

Under the effect of nature condition and social-economic growth condition of Hebei province, the urban system around Bohai Sea in Hebei province showing the characteristic as follows: Firstly, it is divided into two parts of north and south by Beijing and Tianjin. Secondly, the economic strength of the coastal areas is not strong although it near to Bohai Sea. Thirdly, the urban system is obviously draw by two cores and broken up by hinderland. Fourthly, there are great differences between spatial distributions of the cities; they distribute a disproportion in the whole.
