The three-roll planetary rolling process of copper alloy tube was simulated and analyzed by finite element method .

目前三辊行星轧制紫铜管坯的技术已相对成熟，而利用三辊行星轧机轧制铜合金管坯的实验和研究却相对很少。

The structural principle, rolling mechanism and movement rules of the three-roll planetary mill have been introduced.

阐述了三辊行星轧机的结构原理、轧制机理及其运动情况，在对三辊行星轧机分析研究的基础上，设计制造了一种新型三辊旋轧试验机。

Compared four-roll planetary rolling with three-roll planetary rolling, the rolling speed is faster and the deformation of tube is more uniform, higher efficiency and better quality will be gained as a result.

与三辊行星轧机相比，采用四辊行星轧机轧制铜管的轧制速度更快，可以大大提高生产效率；而且管坯变形更均匀，轧出的产品质量更好。

Compared with the three-roll planetary rolling process, the bending stress of the tube decreases greatly during the four-roll planetary rolling process, reducing the possibility of the generation of cracks.

与三辊行星轧制相比，四辊行星轧制管坯的反复弯曲应力显著减小，进而大大减小了在管坯表面形成裂纹的可能性。

Because the earth and other planets orbit around the Sun in the same plane, the planets appear to move through a belt in the sky called the "zodiac".

由于地球和其他行星围绕太阳的轨道在同一平面，行星带出庭动议通过天空叫&生肖&。

Cassini has been orbiting Saturn since 1 July 2004 and is now in its Equinox mission phase that will see the giant planet experience equinox this August, the twice-yearly occasion when the Sun passes through the plane containing the planet's rings.

卡西尼自2004年1月始环绕土星飞行，目前处于Equinox计划阶段。今年八月，卡西尼将要看到这个巨大行星经历昼夜平分点--太阳穿过这个行星环的平面时发生---此现象地球上一年发生两次。

To work out how massive it was, they recorded the motion of the star as it was tugged on by the orbiting planet.

通过计算行星掠过时恒星光线粒子的规模，可以计算出这个行星的半径大小。

As streams of material spiral from the disk onto the star, its mass increases and it brightens and heats up dramatically. The resulting outburst causes temperatures to rise in the star's surrounding disk.

随着物质流从行星盘落向中央恒星，恒星的质量增加并剧烈的变热（重力势能转化为热能——译注），结果产生的爆发导致周围的行星盘变热。

Inquires into the EHL calculation for planetary gear transmission in scraper conveyer,and its calculation formula is derived.

探讨了刮板输送机中行星齿轮传动的弹性流体动力润滑计算，并推导出相应的计算公式；分析了传动润滑状态与磨损的关系，为刮板输送机中行星齿轮传动的耐磨损设计提供了必要的理论依据。

Therefore, the small percentage of white dwarfs that might possess rocky planets probably have larger, gas-giant-like planets as well.

因此，虽然只有小比例的白矮星具有岩质行星，却可能会有大型气态行星。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
