旋转运动

The rotation of the drum produces a relative motion between the filtering screen and the surrounding water making the filtering screen self-cleaning. Nauplii and rotifers thus could be concentrated at high speed to a high density with little damage.

滚筒的旋转会在滤网与周围的水体间产生相对运动而使得滤网面自净，丰年虾无节幼虫与轮虫因此可以在高速下被浓缩到高密度而不会有太大的损伤。

As the inner and outsider baskets rotate at the same speed, the inner one, pushed by the piston, reciprocates axially and repeatedly. As a result, pusher plate pushes the cake layer in the inner basket to move out of it and then into the outside basket for further separation , a ring layer of cake being formed,while the outside section of the inner basket pushes the cake layer in the outside basket to move continuously out of the outside basket and then discharge it through the slot for scraper.

内、外转鼓同速旋转的同时，在活塞推动下，内转鼓连续轴向往复运动，因而推料盘推动内转鼓滤饼层间歇不断地向外移动排出内转鼓，进入外转鼓进一步分离并形成环形滤饼层，内转鼓外端面则推动外转鼓滤饼层间歇不断地向外移动排出外转鼓，经刮料槽排出机外。

"When the record is played back, another stylus responds to the undulations, and its motions are then reconverted into sound."

放声时另一针与纹道接触，当唱盘旋转时，会再变成声音。静力学计算是用来决定照射方向与观察方向之间的角分线方向的运动。

We have day and night and four seasons because of the movement of the earth as it spins in space.

因为地球在太空旋转时的运动，我们有了白天和黑夜和四季。

This removal of air from the pump casing produces a partial vacuum on the pump inlet ,here the fluid is trapped between the teeth of the upper and lower gears and the pump casing .continued rotation of the gears forces the fluid out of the pump discharge .

这种泵内空气运动使泵吸入口处形成了真空，于是外部油箱的液体在大气压的作用下，由泵的入口进入，聚集在上下齿轮和泵壳体之间，齿轮连续的旋转使液体流出泵的出口。

The table cores (micro pills, small pills or plain tablets) to be film coated make continuous complicated orbital motion within a closed rotating drum under the action of a streamline guide plate. Controlled by computer and according to the optimum technological parameters, they are automatically sprayed with film coating medium while hot air under a negative pressure is led in from one side of an air distributing pipe at the center of the drum, clean hot air penetrates through the tablet core layers and is discharged after being collected to the other side of the air distributing pipe by a pore duckbill-shapedair paddle embedded in the tablet core layers, so that the film coating medium sprayed on the surface of tablet cores will dry rapidly and evenly, thereby forming a layer of solid, compact, neat and smooth surface film.

工作原则：表芯被filmcoated不断复杂轨道运动在一个封闭的旋转鼓下一个精简行动，并根据指导plate.controlled计算机优化技术参数他们是在自动喷filmcoating中型热风率领下负压是从一旁的空管中心散发的鼓热风清洁片核心层通过渗透和排出后收集到大洋彼岸的空中散发烟斗孔鸭嘴形在片中空中颤抖嵌入式核心层、使中等filmcoating表面喷洒干燥迅速、均匀地将芯片、从而形成一层坚实、紧凑、整齐、表面光滑电影。

Because the movement trace of rotary piston pump's rotary centroid is a close curve with complicated shape , it is difficult to balance rotary piston pump's inertial force completely.

但滑阀泵旋转质心的运动轨迹是形状复杂的封闭曲线，因此很难实现对滑阀泵惯性力的完全平衡。

The model was oscillated about its body axis with selected pitching frequency and amplitude during its continuous rotation about the wind axis.

模型在绕风速轴连续旋转的同时，进行给定频率和振幅绕体轴的俯仰振荡运动。

From these parameters, the new findings are:(1) The ice density from investigation is lower than 2-3 tenths compared with that from NOAA Ice Chart, and the ice thickness in the summer is less than 2 m compared with the results investigated during the First Chinese National Arctic Research Expedition in 1999 (CHINARE-1999);(2) The standing deviation of ice bottom fluctuation is 3.8 times of that of the snow surface on the ice sheet and (3) the maximum speed of ice floe CHIS7 is 1300 m/h in rotation and oscillation.

这些参数指出：现场调查的海冰密集度同NOAA冰图上的密集度相比低2~3成，而厚度比1999年的中国首次北极考察结果减少2m；冰层底面起伏方差约是冰层表面积雪起伏方差的3.8倍；浮冰最快以1300m/h速度运动并伴随振荡旋转。

The aircraft from the programmable logic controller control, to the winding parameter input into the product can automatically complete the product design, and then control the core mold rotation and car move up and down movement of the compound to soak the fiber resin, according to the law of uniform covered with lining on the product.

该机由可编程控制器控制，，把所缠绕产品的参数输入进去，可自动完成产品的设计，然后控制芯模旋转与小车上下移动的复合运动，把浸透树脂的纤维按规律均匀布满在产品内衬上。

The big eared hedgehog, the little owl, the sand gecko, the three-toed jerboa, and every show needs a villain - saw-scale - the viper!

大耳刺猬，小猫头鹰，沙壁虎，三趾跳鼠，每场戏都需要反派角色：蝰蛇。
