偏心

Driven by the valve stem to close one to wind the rotatory central point while rotating,the spheroid to the third a bit more separately, relative valve central point at this moment,from the third orbit a bit one cam form partial another,enter valve flat make valve it keep sealing to shut off down wards .

由阀杆带动关闭件绕旋转中心点转动时，球体由另点移至第三点，此时相对阀门中心点，从另点的第三点轨迹为一凸轮状偏心，向下进入阀座使阀门关闭保持密封。

In some makes of engine the helically splined coupling is not used and the angular displacement of the shafts is effected by centrifugally actuated devices of the swinging link or inclined plane type.

在一些发动机的制造中，并不使用螺旋式花键套管，通过摇杆或斜面型的偏心操纵装置，曲轴相位角起到同样作用。

V belt driving device developed is superior to flexible plate coupling and roller chain driving in VNH behavior, working endurance and axial and lateral offset tolerance.

所开发的三角带传动装置在振动噪声性能、作寿命和对轴向以及径向偏心的容忍度等方面都优于常用的柔性板式联轴器和高速滚子链传动装置。

The inner rotor is eccentrically mounted on a crank, and spring-loaded by a sort of circlip A so that the rotor extremities maintain contact with the inside of the housing, and the volumes of the chambers so created therefore increase and decrease as the crank turns.

内转子是偏心安装在一个曲柄，弹簧加载由一种circlip一，使转子四肢保持联系与内部的房屋，以及大量的分庭，以便创造的，因此增加和减少由于曲柄轮流。

The relationship between accumulative error of circular pitch and amount of motion eccentricity has been investigated.

最后考察了周节累积误差和运动偏心量的关系。

Increasing the eccentricity can decrease circular section of the rotor and lead of stator with similar single displacement .

同样的单转排量的情况下，增加偏心距，就可以减小转子园截面或定子导程。

We obtain the theorem of closed ball case in the continuous probabilistic metric space and the complete character theorem of Menger space.

Methods: Sixty-three patients with EMR were studied with the continuity equation method and the VC method. And those results were analyzed in their correlation and regression based on the continuity equation method as a "reference standard".

对63例二尖瓣偏心反流患者分别用连续方程法及射流紧缩面法测量二尖瓣反流程度，以连续方程法结果为标准，分析二者的相关性，建立线性回归方程。

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%.
