A mathematical model was developed to investigate the molten steel flow and decarburization process in RH vacuum degasser system under the action of electromagnetic field.

为了了解旋转磁场下真空精炼装置内的脱碳反应，对RH装置内钢液流场与脱碳过程进行了耦合计算；采用修正的均相流模型计算流场，避免了先前的一些不具推广性的方法，如简化计算区域或者预先规定含气率分布等。

The results are as follows:(1) With the imposing of orthopedic force of simulating maxillary protraction on maxilla, in the sagittal direction, the maxillary complex of the SD Rats in experimental group grows more quickly than that in two control groups, and the extent of the maxillary complex increases more evidently. The maxillary complex displays anti-clockwise forward and upward rotation.(2) With the imposing of orthopedic force on maxilla, upper incisors exhibit labial-inclined, labioclination of lower incisors changes insignificantly, and the shape and the dimension of skull are not affected significantly.(3) The expression of TGF-3 , in frontomaxillary sutures and palatomaxillary sutures shows different intensity in different extent of time. But The expression of TGF-{3, in experimental group is more intensive than that in two control groups, and that in operated control group and natural growth group has no significant difference.

结果如下：在模拟上颌前牵引矫形力作用下，(1)生长发育期大鼠上颌复合体在矢状方向生长加快，长度明显增加，并表现出向前向上的逆时针旋转；(2)上切牙唇倾，下切牙的唇倾度没有明显变化，颅脑的形态与大小不受影响；(3)额颌缝和腭颌缝中TGF-β_1的表达，同一时段实验加力组要强于手术对照组与自然生长组，而手术对照组与自然生长组之间无显著性差异。

It is shown that even for the case of vanishing IMF strength the bow shock is not rotationally symmetric with respect to the Sun-Earth line: the east-west dimension of the cross section of the bow shock exceeds the north-south dimension by about 9~11% on the terminator plane (dawn-dusk meridian plane) and its sunward side, and becomes smaller than the north-south dimension by about 8% on the tailward side of the terminator plane.

模拟结果表明，即便对于IMF强度为零的情况，弓激波相对日地连线也不具备旋转对称性质：终端面及其向阳侧的弓激波截线的东西宽度大于南北宽度（约9%~11％），终端面尾侧的弓激波截线东西宽度小于南北宽度（约8％）。

But they are not effectie against translatory or rotatory forces, and a high failure rate has followed.12–14 In order to increase the stability, Magerl and Seeman added transarticular C1–C2 screws, which hae mechanical adantage and lead to a higher fusion rate (range,87%–98%).15–19 We found that all the reports in the recent English literature were screws combined with wires or clamps.

这些方法不能提供对抗横移和旋转力两，有报道的较高失败率12-14。为了提高稳定性，Magerl和Seeman在增加了经关节C1-C2螺钉，该螺钉具有力学优势并能提高融合率（范围在87%~97%）。15~19 我们发现进来的英文文献都是使用的线或椎板钳和螺钉结合的技术。

Ospreys specialise in catching slippery fish. Unlike other birds-of-prey, they have four powerful toes of about equal length, while the outer one is reversible and can swivel backwards or forwards.

通过对以光滑鱼为猎食的鱼鹰进行研究发现，它不象其它的食肉鸟类，它有四只同样长而非常有力的爪，并且最外边的一只是可以钩回和前后旋转。

Galileo's greatest glory was that in 1609 he was the first person to turn the newly invented telescoped on the heavens to prove that the planets revolve around the sun rather than around the Earth.

伽利略的最光辉的业绩在于他在1609年第一个把新发明的望远镜对准填空，以证实行星是围绕太阳旋转而不是围绕地球的。

Since the edge of the hole is not a simple circle but a 3-dimensional curved line, the chamfering has been conducted by skilled workers with files, whetstones or rotary-bars.

因为洞的形状不是单一的圆环状，而是三维曲面的，斜面清毛刺都是由经验丰富的工人用锉刀、魔石和旋转杆来操作的。

An accurate and well-adapted simulation method of projection data for cone-beam CT, which can describe the details of each tomography, is proposed in this paper.

在重建算法的研究过程中，模拟投影数据是必不可少的一部分，一方面可以避免实测投影数据的误差，为后继CT重建算法提供理想的投影数据；另一方面也可以根据需要有选择地模拟失真如：探测器偏移、旋转、响应不一致，射线源

Test results have shown that larger plastic volumetric strain as well as higher growth rate of pore water pressure would be generated in multi-directional shearing than in a single-directional one. Lower resistance of sand to liquefaction was also observed under the rotation of principal stress orientation.

与单向剪切相比，多向剪切会产生额外的塑性体积应变，在不排水条件下孔隙水压力增长的速率较高，特别是在具有主应力轴连续旋转特点的加载条件下，砂土抵抗液化的能力也将更低。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
