Special solutions for the ring circular domain with crack surfaces acted on uniform compressive force, linear compressive force and linear shearing force are deduced in polar coordinate employed the eigenfunction expansion technique in the Hamiltonian system of elastic mechanics. Combined with the general solution for the above problems, the analytical solutions for crack tip fields with surfaces acted on the above three kinds of loads are obtained. These solutions offer theoretical basis to construct analytical elements for plastic analysis of crack.

Finally it analyzes the feasibility that using hydromechanics to analyze traffic flow by contrasting various characters between traffic flow and fluid flow. It analyzes influence of road alignment to basic expressway segment capacity by hydromechanics, and obtains viscous resistance and viscous movement differential equation when the vehicle drives on circular curve segment of expressway. And it infers that viscous resistance is correlated with sideway force coefficient, slope of crown and radius of circular curve. Radius of circular curve, sideway force coefficient and slope of crown are bigger, viscous resistance is smaller, the influence to capacity is smaller when the vehicle is running on nearside lane of circular curve; but radius of circular curve and sideway force coefficient are bigger, slope of crown is smaller, viscous resistance is smaller, the influence to capacity is smaller when the vehicle is running on fast lane of circular curve.

最后通过对比交通流与流体流的相似性，运用流体力学分析了道路线形对快速路基本路段通行能力的影响，求出了车辆在曲线路段的粘性阻力，建立了车辆在曲线路段的粘性运动微分方程，并由此推知，粘性阻力与横向力系数、路拱横坡度和圆曲线半径都有关系，当车辆在圆曲线外侧车道上行驶时，圆曲线半径、横向力系数和路拱横坡度越大，粘性阻力就越小，对道路的通行能力影响就越小；而当车辆在圆曲线内侧车道上行驶时，圆曲线半径和横向力系数越大，路拱横坡度越小，粘性阻力就越小，对道路的通行能力影响就越小。

Recently, auspicious of clean of Ba of committee member of committee of right of children of Indian government protection (Sandh-ya Bajaj) is in force of a children expresses on problem informal discussion, create children liability bloody force, besides domestic education undesirable be advocate so outside, the apply colours to a drawing of clue of force of the ride roughshod over between the moral education inadequacy that also includes the school, compeer and movie and TV, game.

近日，印度政府保护儿童权利委员会委员芭洁吉(Sandh-ya Bajaj)在一项儿童暴力问题座谈会上表示，造成儿童倾向血腥暴力，除了家庭教养不良是主因之外，也包括学校的道德教育不足、同辈之间的欺凌与影视、游戏暴力情节的渲染等。

Near to 0 point, the force accumulation is more and more and produces heavy substance, which is lighter more externally. At the time the force is accumulated more, the accumulation of force is certain bigger, and the space of corresponding 1 degree goes back to 0 degree when one side or one point returns to 0 degree, and the composition of forces each other is more than their repulsion, and the repulsion of final composition point is bigger than that of repulsion themselves, push them to different directions quickly, and stop until repulsion among them is equal to their repulsion.

离0点近的，力积累越多形成的是重物质，越往外越轻，这时候力越积累越多，力的积累也相当的大，相对应的1度的空间，在一面或一点都回到0度，互相斥力的合力大于他们自己的自身的斥力，最后合力点大于了他们自身的斥力，把他们快速推向四方，直到他们之间互相斥力的合力等于他们的斥力才停止。

Where the first term in the above equation refers to a conservative force, the second to a dissipative force and the third to a random force.

第一项是保守力，第二项是耗散力，第三项是随机力。

And the upper neck force was affected by the contact force and the head inertial force.

假人模型的上颈部所受剪力和拉力均较大，而儿童人体有限元模型的上颈部剪力较小，拉力较大。

It is a slow evolvement under quasi-balance of inertial force, Coriolis force and pressure gradient force.

显然，这种准平衡态是惯性力、柯氏力和气压梯度力三者之间的平衡。

The numerical results were proved to be reliable by comparing with some published experimental data. The results show that, when only Coriolis force is in effect by omitting the centrifugal buoyancy force, the flow in the cavity is axi-symmetrically stable, the Coriolis force is a kind of resilience, and does not cause flow unstably.

研究结果表明：在哥氏力的单独作用下轴向通流旋转盘腔内的流动基本上是稳定的三维轴对称结构，即使有轻微的径向或周向振动发生，由于哥氏力是恢复力，对其有抑制作用，因此振动会随着流场的发展逐渐消失。

Although we can see that radiative correction term is less than the contribution of the free gauge field to the Casimir force, our result of the radiative correction to the Casimir force of M-C-S gauge field at zero temperature, will possess referenced value for measure of the Casimir force experimentally.

从所获得的量子涨落对M-C-S规范场的Casimir力的辐射修正的结果来看，虽然辐射修正值与自由规范场对Casimir力的贡献相比小的很多，但对于提高测量Casimir力的精度，将会提供可参考的理论依据。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.
