产生动力的

The results show that under the action of the ponderomotive force of the coupling laser, there are a larger divergence of the density profile of the electron and ion in the laser-plasma than that without Compton scattering, the faster change of the electron density than the ion density, and the stronger electrostatic field than that without Compton scattering.

研究发现，在耦合激光的有质动力作用下，电子密度分布和离子密度分布比Compton散射前的偏离更加严重，电子密度的变化比离子密度的变化更快，产生的静电场更强。

One type of students are those who are short of study motion. This type of students can be divided into four situation. That is the contradiction between demands and realities, the repound after pressure, they have ever been defeated, they negate the value of study, Another type of students are those whose knowledge is not enough. Their previous knowledge can't catch up with the teaching demands of a vocational school. The third type of students are those who have no suitable study methods and good learning habits. The fourth type of students are the synthesis of all above.

其次从学生主观角度分析，其化学学习障碍产生的原因可分为四种类型：一是学习动力不足，这类学生又可大致分为四种情况，即需求的倒错、压力的反弹、心理曾经受挫和否定学习的价值；二是先备知识不足，表现在其先备知识与中专教学要求的不相称上；三是学习方法和习惯不好；四是综合体现上述三种原因。

Its generated mechanism is that poten-tial instability is touched off by the convergent and thermodynamics near theground in the favourable weather controlled by trough of high altitude.Thatmakes effective potential energy release greatly, forming strong convection.Meanwhile, intensive storms with convection are occurred because of the plentyof moisture flowing into the basin and favourable topograph...

吐鲁番盆地的大降水具有降水时间短、强度大、范围小，雨量集中等特点，它的发生机制是在高空低槽控制的有利天气形势下，地面动力辐合作用和热力作用触发了大气中的潜在不稳定结构，使得大气有效位能大量释放，形成强烈的对流；同时，有充沛的水汽输入盆地，在有利地形条件下，产生强对流暴雨。

A direct yaw moment control controlling vehicle motion by a yaw moment which is actively generated by transversally distributed tire longitudinal forces is becoming one of the most promising means of chassis control for the improvement of vehicle active safety.

通过控制左右车轮上的驱动力和制动力，产生横摆力矩来控制汽车的横摆运动的直接横摆力矩控制技术，可以有效地提高汽车的操纵稳定性。

The glucose-6-phosphate dehydrogenase increased during overw intering,indicating that reduced condition of cell might keep the cell in pr oper function even in cold temperature,and also for cryoprotectant synthesis.The changes in trehalase activity showed that low activity was for keeping higher tre halose content and high activity for removing it in the spring.

越冬期间，体内葡萄糖-6-磷酸脱氢酶活性增高所产生的还原型烟酰胺腺嘌呤二核苷酸磷酸，可为细胞在亚低温状态下发挥正常功能以及体内抗冻保护性物质的合成提供还原动力，同时通过调节体内海藻糖酶活性来维持越冬期间较高含量的海藻糖和移除春季体内累积的过多的海藻糖。

It is not that Economic Law carves up the administration Law'sorbit but that the administration Law definitudes its direction of advancing much more.Each has its background of origination and sphere of learning,and they drive along dif-ferent roads,advance together and make progress.Civil Law and Commercial law andEconomic Law all serve as a solution to marketing failure and over—amount trading ex-penses caused by marketing failure.

笔者认为，行政权的扩张一因数果，既是经济法产生的原因，亦为行政法最终形成和发展动力，不是经济法&瓜分&了行政法的势力范围，而是行政法更加明确自己的前进方向，两者各自其来有素，术业有专攻，齐头并进，分途而赴，合力以成。

The main contents include the kinematic and dynamic characteristics of floating body and concept about large body; the kinematic and dynamic conditions and governing equations for constrained floating body; illumination of simple harmonic by decomposition into diffraction and radiation; introduction of relevant effect forces; the formula of velocity potential in waters with constant depth; the scattering by a vertical cylinder with circular cross section.

简述浮体的运动及动力特征、大尺度物体的概念；受约束浮体的运动学及动力学条件及其控制方程；通过分解为绕射和辐射问题讲解简谐运动及有关的作用力；等水深地形上速度势的表达式；铅垂圆柱产生的散射。

The reduction in engine size has brought better efficiency, as there is less power loss resulting from friction.

发动机尺寸的减小带来更优的效率，更少的由麽擦产生的动力损失。

The Leaf sources power mainly through photovoltaic cells within its leaf-shaped roof (these position themselves toward the sun to garner the most energy) while mini turbines within the wheels use the passing wind to generate electricity and store it in its battery pack, supplementing power for the microbial fuel cell.

LEAF的动力来源主要通过内置在自身叶片顶棚里的光硒电池（它自己的这个位置朝向太阳收集并储藏更多的能量）在此期间在轮子内部微小的涡轮机通过风产生电能并储藏在它自己的蓄电池组里供应能量给微生物燃料电池。

To set the coefficient determinant for zero to solve the characteristic equation of one-layered plate, and to calculate the dispersion equation of any layered plates with recursive matrix method.

层状板当上下表面为自由边界面时板中将会产生板波，文中通过求解行列式和采用传递矩阵法分别得到了单层板和任意层板的特征方程，研究了单层板和双层板中板波的频散特性和板中位移和应力的分布，讨论了板波的动力响应，对测点的布置有一定的指导意义。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
