Therefore,the elastic resistance is augmented , which makes electric current fluctuate excessively ,the reductor abraded and binded ,and the tyre worn out badly .Thus ,the operation has to be suspended.By means of mechanical property and finite element analysis and calculation of the tyre...

通过力学性能及轮胎有限元分析计算，认为必须改进传统设计使筒体的转动方向与传动装置反向，这样可以在非传动侧均匀设置支撑，以减少主动侧、被动侧的支反力，即减少轮胎的弹性变形阻力矩，达到保护减速机的目的

Reflector telescope relative a larger diameter can be done, the main focus of the relative telescope diameter is about 15-125, even greater, Wang DC, inter Newton Telescope, the tube is longer than the system is much shorter focal length, coupled with the main mirror is only one apparent need for processing, which greatly reduces cost and manufacturing difficulties, there is currently greater than 134 meters diameter optical telescopes are all reflecting telescope.

反射望远镜的相对口径可以做得较大，主焦点式反射望远镜的相对口径约为15—125，甚至更大，而且除牛顿望DC远镜外，镜筒的长度比系统的焦距要短得多，加上主镜只有一个表面需要加工，这就大大降低了造价和制造的困难，因此目前口径大于134米的光学望远镜全部是反射望远镜。

My father used to have all these interesting optical instruments, such as binoculars, and a reflex camera which I later obtained to use.

父亲以前有许多好玩的光学仪器，像双筒望远镜，反射式照相机，后者我得以继续使用。

Usually less than 10 cm diameter refracting telescope.

附加在望远镜主镜镜筒上的小型目视望远镜。

Though the gyration and retroflexion of the workbench, the welding positioner can make the welding line to an ideal position, which can improve the quality of the welded joint, reduce welder's workload. It is ideal equipment especially fit to weld the kinds of workpiece, just like the shaft, tray, canister, and so on.

焊接变位机可水平翻转角度，通过工作台的回转及翻转运动使工件上焊缝处于最理想的位置进行焊接，从而大大提高焊缝质量，减轻焊工劳动强度，尤其是适合焊接各种轴类、盘类、筒体等回转工件的理想设备。

Draw V,H views of the cutting right cylinder.

求圆柱筒被截切后的H 、W面投影。

The second is a special bond with the Road Agent will be in full closed (sealed expansion ring outside diameter less than diameter of the plunger body) state seal, with the sucker rod string and then go down the plunger, the plunger into the After the pump barrel and pump the same as rotating the impulse from the ordinary because of the improved Baptist slot only temporary pressure seal forms, go down soon after the sand to achieve sealing and resistance functions.

而其余各道密封在柱塞下入泵筒中2~7d内也全部打开。

In 1986-five years after IBM researchers Gerd Binnig and Heinrich Rohrer invented the scanning tunneling microscope, which garnered them the Nobel Prize-the book Engines of Creation, by K.Eric Drexler, created a sensation for its depiction of godlike control over matter.

一九八六年——ibm公司的研究人员盖尔德·贝尼格和海因里希·罗利尔发明扫描筒状显微镜的五年之后(他们因此而获得诺贝尔奖)——埃利克·德莱克斯勒所著《创造的动力》一书轰动一时，因为书中描写了如上帝般控制物质的能力。

The basic performance and designing principle of a kind of elastic layer material, which were applied in the Roller Mill to reduce the machine noise, were introduced.

研究了作为火电厂球磨机筒内降噪弹性垫层材料的基本性能及设计原则。通过试验和工业现场运用表明，垫层材料和安装方式是可行和安全的，且有明显的降噪效果

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
