查询词典 gravitational mass

Dr Clowe and his colleagues used a technique called gravitational lensing to detect the mass distribution of the bullet cluster.

克洛韦博士及其同事们使用一种称为引力透镜（注1）的技术来探测子弹状星系团的质量分布情况。

Further studies of this cluster are needed to explain the lack of agreement ,between mass estimates based on the X-ray data and on the gravitational lensing.

以后对于这个星系群的研究需要被用来解释关于基于用X射线数据和引力透镜估算质量的不协调问题。

A Jupiter-mass exoplanet was detected in 2000 by the radial velocity method in which astronomers look for wobbling motion of a star due to the gravitational tug of a planet.

在径向速度法中，天文学家们往往寻找恒星摆动的迹象，这种摆动是由于行星的引力作用造成的。

In the case of planetary formation, the gravitational interactions between the dust in the disk, the mass in the larger aggregates of material, and the sun itself plus the friction of the material, its thermal properties, and the interaction between the magnetic fields from the star and those of the disk material itself plus countless other factors may be vital in order to understand how planets like our own form from the primordial disk of stardust.

在行星形成的研究中，碟状星尘之间重力的互动、较大聚集物的质量、太阳本身与这些物质间的摩擦、物质间本身的摩擦、物质本身的热力性质、太阳磁力场中这些物质的互动及磁力的影响，加上其他的无数因子都可能是了解地球如何从星尘中诞生的关键。

In deep space laser ranging missions for gravitational-wave astronomy, astrodynamics and test of relativity, like LISA, ASTROD I and ASTROD, charging of drag-free test mass due to exposure of the spacecraft to various energetic particles in the space environment can affect the quality of the science data due to spurious Coulomb and Lorentz forces.

在LISA， ASTROD I和ASTROD之类用于探讨引力波天文、天文动力学和相对论测试的深空激光探测计划中，暴露在空间粒子环境中的无拖曳测试质量将会受各种带电粒子的影响而带电，引起库伦力和洛伦兹力干扰，从而影响实验数据的精度。

In Doppler effect, Gravitational red shift and Compton effect as it changes frequency the photons (including γphoton ) always abide by constant principle of light speed ,which proved that the photon has zero mass.

在多普勒效应，重力红移和康普顿效应中，光子在频率发生变化时总是遵守光速不变原理，由此证明了光子具有零质量。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
