查询词典 gravitational mass

In this paper, from the equations of motion, we obtain the orbital and mass defect effects in the gravitational field.

中文摘要：本文从引力场中运动方程出发得到了引力场中的轨道效应和质量亏损效应。

In 2005, we have fulfilled the improved experiment, which included a new cave laboratory with more homogeneous gravitational background, a modified pendulum with a quadrupole moment of mass distribution to further quiet the contribution from the local gravity gradients, a high vacuum chamber to suppress the disturbance from the residual air current, the synchronous monitors of the rotating period of the turntable and temperature, the modulation experiment of background magnetic field, and so on.

新的实验中进一步克服了2002年实验中的背景引力梯度的影响，同时还进行了温度、回转周期稳定性的同步检测和磁场影响的调制实验，以及数据处理方法的研究，进一步提高了实验的置信水平。

"Dark matter : Nonluminous matter not directly detectable by astronomers, hypothesized to exist because the mass of the visible matter in the universe cannot account for observed gravitational effects."

暗物质：不发光的物质，天文学家无法直接发现，由于宇宙可见物质的质量无法解释观测到的重力效应而假设其存在。

"Dark matter : Nonluminous matter not directly detectable by astronomer s, hypothesized to exist because the mass of the visible matter in the universe cannot account for observed gravitational effects."

暗物质：不发光的物质，天文学家无法直接发现，由于宇宙可见物质的质量无法解释观测到的重力效应而假设其存在。

"Dark matter : Nonluminous matter not directly detectable by astronomers, hypothesized to exist because the mass of the visible matter in the universe cannot account for observe d gravitational effects."

暗物质：不发光的物质，天文学家无法直接发现，由于宇宙可见物质的质量无法解释观测到的重力效应而假设其存在。

A self-luminous celestial body consisting of a mass of gas held together by its own gravity in which the energy generated by nuclear reactions in the interior is balanced by the outflow of energy to the surface, and the inward-directed gravitational forces are balanced by the outward-directed gas and radiation pressures.

星，天体：本身能发光的天体，由自身吸力吸引的大量气体组成内部核反应产生的能量流向表面，向内的引力通过逃逸的气体和放射压力相抵消来达到平衡

Part of this precession is attributable to the perturbing gravitational field of the other planets, and part can be explained in terms of the special relativistic increase in mass due to the planet's motion.

这种运动部分是由于其它星体的万有引力场的扰动，还有部分可以用狭义相对论的星体运动引起质量增加来解释。

For fiatΛCDM cosmogonies withσ8 normalized by recent weak gravitational lens-ing observations, the best results are obtained forΩ0～0.3;Ω0≤0.2 leads to too large galaxy correlation lengths, whileΩ0≥0.4 gives too high mass-to-light ratios to match the observed TF relation.

对于平直ACDM宇宙学模型，根据最近的弱引力透镜给出的σ8值，条件光度函数模型给出了最佳值为Ω0～0.3；当Ω0≤0.2时，星系相关长度过大；而Ω0≥0.4则给出了太高的质光比，和观测的TF关系不符合。

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

克洛博士和他的同事使用一种叫做引力透镜的技术来探测子弹状星云团内物质的分布情况。

The concentration of mass is determined by analyzing the effect of so-called gravitational lensing, where light from the distant objects is distorted by intervening matter.

通过所谓的引力透镜分析了大规模的的物质集中区。在引力透镜这块区域内，来自遥远天体的光线在这被扭曲。

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%.
