长半径

The results show that the tube pitch is the key factor that affected the size of uniform heated area, and the tubes arrangement has not notable effect on irradiance uniformity; When L/R is increased, Lobj at which the irradiation distribution is uniformly on the heated object surface is increased.

通过计算得出定向反射管间距是影响均匀加热面积大小的主要因素，管束布置方式对辐照度均匀性影响较小；随管长与半径比增加，物体表面辐照度均匀时，对应的加热距离增加。

A large handle size gives more area to apply friction and a wider radius to apply the frictional force in order to resist racquet twisting about its longitudinal axis (Torsion, or Longitudinal Torque) on off-center hits.

大的手柄尺寸可以提供更大的面积来增加磨擦力，更宽的半径能产生磨擦力来阻止没有击中中心时球拍绕长轴的翻转。

By setting up mechanical model, the relationship of curve radius, jacking force and effect factors such as pipe diameter, length of pipe section, thickness of wooden piece, elasticity of material and the difference of jack displacement is investigated.

通过建立力学模型对曲线路线半径R、顶推力P和影响因素如管径D、管节长L、木垫片厚a、材料弹性模量E以及工具管油缸行程差等的关系进行推导。

The steam line will reduce the fluid resistance to is smallest, the slow circular aperture's design can reduce the rapids and the pressure, the long curving radius of action will have the good mobility.

蒸汽线路会把流体阻力减到最小，较缓的圆形孔径的设计能够减少湍流和压力，较长的弯曲活动半径会产生较好的移动性。

The product has to bear the high stress, bending radius of the small, anti-fatigue performance, long life and other characteristics, widely used in metallurgical side casting, oil drilling, engineering machinery, mining and all kinds of hydraulic mining machinery.

本产品具有承受压力高、弯曲半径小、抗疲劳性能强、使用寿命长等特点，广泛应用于冶金边铸、石油钻探、工程机械、矿山采掘及各类液压机械等。

Influences of related parameters on the irradiation intensity and uniformity along the object surface were analyzed, such as the arrangement (in-line or staggered and the distance between tubes), the distance between the object and the burn, the tube pitch and the ratio of tubes length to radius.

利用蒙特卡罗法中的辐射分配因子计算并分析了相关参数，例如管束布置、加热距离、管间距及管长与半径比等对被加热物体表面辐照度均匀性的影响。

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％。
