This paper introduces the research results of techniques of testing PC pump oil well through one-year efforts. Which covers the mathematical models of a number of force characteristics strength analysis, and resonance critical problems of rotation rod-string in PC pump wells: resulting of testing method of polish-rod load and rotation rate on the basis of feasible demonstration and technical requirement analysis; study and manufacture of system of testing PC pump well, which involves sensor, collector ring, acquisition circuit and computer; research and determination of assistant technology of testing force on rotation polish-rod and formulation of testing force on polish-rod. A spot testing has been carried out by means of the above research fruit and good results have been achieved.The success testing results in has laid a strong foundation for the oil well diagnosis.

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。

Based on the law of universal gravitation and Coulomb's law, the law of gravity, weak force, strong force and unified force are founded.

统一力定律能够把万有引力定律、库仑定律、弱力定律、强力定律这四个基本力定律统一起来。

It is shown that the friction force and bulkhead thrust are the main factors of shield thrust setting, while the friction between the cutterhead and soil is the main factors of cutterhead torque setting. Friction force between shield and soil would make front soil of shield upheave, and subsidence of surface soil is induced by ground loss when the friction force between the cutterhead and soil results in the surface settlement asymmetrical distribution.

通过计算发现，盾构施工中盾壳摩擦和正面推力是盾构推力设置的主要因素，而刀盘与土体摩擦是刀盘扭矩设置的主要因素，盾构前方土体隆起主要由盾壳摩擦引起，刀盘摩擦作用主要引起地表沉降的非对称分布，地表沉降主要由盾尾空隙产生。

Three different calcium oxide catalysts were synthesized from different precursors and characterized by X-ray diffraction, scanning electron microscopy, and temperature-programmed desorption.
