回转

Having absorbed all advantages from exotic machines and designed according to the standard of ASME, this harrow has adopted combined structure whose rigid frame is welded with square tube, equipped with hydraulic up-and-down road wheels, spring leveling device and sealed bearing with spheroid outer surface and square inner hole special for disc harrow.

此耙吸收了国外同类先进产品的优点，按部颁标准设计，整机采用组合式结构，以方型焊接管整体式钢性耙架为主体，配有液压起落运输轮，弹簧调平机构和圆盘耙专用的外球面内方孔密封滚动轴承，结构合理、坚固耐用，运输方便，回转半径小，易于调整，便于维护保养，是目前国内先进的圆盘耙产品。

In this paper, we have certificated the correctness of the simulation mathematic model and the prediction programs by calculating horizontal stationary turning circle motion and vertical stationary submergence motion, and then have predicted the six motions of tow submarines in order to get the feature motion parameters and the motion track of the center.

本文首先通过对潜艇水平面定常回转运动和垂直面定常直线潜浮运动的计算，验证了仿真数学模型和预报程序的正确性，然后分别仿真预报了两艘潜艇的六种运动的特征运动参数和重心运动轨迹，其预报结果符合工程实际，能够较为全面地反映潜艇的空间操纵运动。

The furnaces including stands, transferring and loading devices, vertical door, hot air circle parts, level door, frock, control devices, temperature transducer.

由公司总经理刘林海先生设计，于2004年12月获得国家实用新型专利，该全自动回转输送式退火炉包括机架、运载机构、垂直门、热风循环装置、水平门、工装、控制装置、温度传感器。

The integrated fixed surface drive system and the controllable hydraulic trim tab system keep the boat optimal conditions at sea.

该艇采用集成化的固定式表面桨系统，配备液压可调的压浪板装置，使艇在风浪中航行、回转等状态时，仍能取得最佳航态。

Because of the rotary pump parts, lower inertia, it can use a high speed

3因为泵内的回转部件惯性力较低，故可使用很高的转速

Because of the rotary pump with a lower inertia force components, it can use very high speed

因为泵内的回转部件惯性力较低，故可使用很高的转速

Compared with other rotary pump, the gas entering and less sensitive to dirt

与其它回转泵相比，对进入的气体和污物不太敏感

Rotary pump and industry on the emergence of the liquid delivery requirements of the relevant increasingly diversified.

回转泵的出现与工业上对液体输送的要求日益多样化有关。

Since the rotary pump with a lower inertia force components, it can use very high speed

3因为泵内的回转部件惯性力较低，故可使用很高的转速

His podium manner was dramatic, too: gesticulations, gyrations, crouches, and sometimes the famous"Lenny leap."

他的指挥风格包括手势、回转、卷缩、&李宁跳跃&也是戏剧性的。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
