The Circulation-hydrogenation Compressor Model BLC-305/A is an important equipment with Hydrogenation devices, which is imported by Lanzhou Petrochemical Company Refinery. Due to high-speed rolling periodically, the spare parts of this compressor, to a varying extent, show a lot of signs of wear and tear. Especially, the axle sleeve of the rotor axle of the compressor is so worn to the greatest degree that its work efficiency decreases by a big margin. Machinery Factory of Lanzhou Petroleum Processing and Chemical Complex has undertaken this task to repair the rotor.

BCL—305/A型循环加氢压缩机是兰州石化炼油厂从国外引进的一台用于加氢装置的重要设备，该设备经长周期的高速运转，零部件均有不同程度的磨损，特别是压缩机转子轴上的轴套磨损程度最大，使整机效率大幅度下降，兰炼机械厂承担了这项转子修复任务。

The other method to improve the efficiency for the optical tweezer is to change the microrotor's configuration. The results show that rotor speed of the microrotor is about 10^(-7) as large as that of the cross-shaped rotor.

The suitability of the different processes was analyzed by observing the weld appearance,studying the microstructure and measuring the mechanical properties of the joint.The results show that a favorable weld can be obtained under the suitable parameters by laser beam welding or tungsten inert gas welding with filler metal.The TIG welded joint has a wider HAZ,and the laser welde...

试验结果表明：在工艺参数合适的条件下，加焊丝TIG焊和激光焊均能获得成形较好的焊接接头；TIG焊接头热影响区较宽，焊缝深宽比小，而激光焊时热影响区不明显，焊缝深宽比大；两种焊接方法所获得的焊缝区组织均为均匀的等轴晶，但激光焊时焊缝组织更细，从而使接头抗拉强度大幅度提高，达到母材的94%左右。

Therefore, when there are several methyls/methylenes in the system, and our focus isn't on the diffusion perpertie, the UA force field is our first choice.(4) UA force field was proposed for phosphonium-based IL, and molecular dynamics simulations were performed to depict the aggregation.

因此，如果一个研究体系含有较多的甲基及亚甲基基团，这些基团对体系的相互作用影响不大，而且体系的扩散性质不是研究的重点，则可以选取UA力场代替AA力场，在保证结果精确度的同时大幅度地节省计算资源。

The results showed that the stearates can accelerate the development of PTG material. The addition of NiSt2 greatly increased the maximum density and the sensitivity together with a slight fog increase. However the addition of BaSt2 and CaSt2 did not make such great increase in the maximum density and the sensitivity, together with a slight fog decrease.

结果表明，MSt2的加入可促进PTG材料的显影，其中加入硬脂酸镍(NiSt2)后在灰雾增加不大的情况下，最大密度和感光度大幅度提高，而加入硬脂酸钡(BaSt2)和硬脂酸钙(CaSt2)后在抑制灰雾的同时，最大密度和感光度也有一定程度的增加。

In this model, the velocity was controlled below50 m /s so that it is easy that the temperature of outlet propellant exceeds 1000K. By the measure of advancing the melting point of metal panel to 3000K, the temperature of outlet propellant even could be close to the very high temperature of the metal panel. It is very active to improve the capability of the whole propulsion system.

在本文模型中，将管道内工质的流速控制在50 m /s ，热交换器的出口工质温度就能够提升至1000K以上；提高换热器高温加热段的金属平板熔点到3000K以上，完全可以将工质出口温度提升至接近金属平板的温度，这样可以大幅度提高推进系统的性能。

The results were as follows: with the shortened distance from the forest edge, photosynthetic rate of rice quadrats were gradually reduced; while the temperature, relative humidity and CO2 concentration in rice population did not change significantly; rice yield declined in a row, mainly because of a significant decreased panicles per unit area.

结果表明，随着与林缘距离减小，样方水稻的光合速率逐渐降低，而水稻群体内的温度、相对湿度和CO2浓度的变化不明显；水稻产量连续下降，其主要原因是单位面积穗数的大幅度降低；而不同林缘距离样方水稻的千粒重和结实率变化甚微。

By analysising the datum in different prestressing force of piston spring shows that raising the prestressing force of piston spring only have a small influence on stroke time to keep the other paramters in costant, but the back stroke time will be decreased and the frequency, the percussive energy and the hydraulic efficiency will be increased rapidly.

对不同锤簧予压力下液动冲击器性能变化的试验数据处理、分析得出：在保持液动冲击器的其它参数一定时，增加锤簧予压力对冲程时间影响不大，但可以大大缩短返程时间，大幅度提高冲击频率、冲击功和液动冲击器的水力利用效率，增加锤簧的予压力是提高液动冲击器性能的一种有效手段。

With ASFC technology, it shall be possible to increase efficiently fan/compressor pressure ratio, but also reduce the axial length and weight of the engine a well as the noise of fans. Meanwhile, it increases the flexibility sad payload of the flight vehicle, thus reducing the fuel consumption.

这一技术的采用能够大幅度提高压比，减少发动机的轴向长度和重量，降低风扇的噪音；在做功能力增加重量减轻的同时，能够增加飞行器的灵活性以及有效载荷，从而减少燃油消耗。

Pedal movements of icing and follow the great link and drive the little link, had to lower hip, the orders of having an effect of the knee, ankle joint; Supporting in the initial stage push-off and adopts the weight and pedals this kind of passive form of ice and pedals the ice only, The ones that are supporting on later stage and adopting by a large margin only are pedaling icing the speed that the way improves the centroid voluntarily, It is typical outburst type movements that this kind pedals technological movement of ice.

蹬冰动作遵循大环节带动小环节、由上至下髋、膝、踝关节的发力顺序；在单支撑蹬冰的初期采用体重蹬冰这种蹬冰方式，在单支撑后期采用采用大幅度快速蹬伸的蹬冰方式来提高质心的速度，这种蹬冰技术动作是典型的爆发式动作。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
