引力

Even so, the gravity of neutron stars is immense.

即便如此，中子星的引力是巨大的。

Newton's Law of Universal Gravitation shows that the material in the universe impossible role in the gravitational stability of the state.

牛顿的万有引力定律表明，宇宙的物质在引力作用下不可能处于稳定的状态。

Before the advent of general relativity, Newton's law of universal gravitation had been accepted for more than two hundred years as a valid description of the gravitational force between masses.

到来前广义相对论，牛顿的万有引力定律已接受超过二百年作为一种有效的说明群众之间的引力。

This is readily apparent in that they refer to the Newton's 'Law' of Gravitation whilst Special Relativity and General Relativity are given the polite attribution 'The Theory of' or simply SR 'theory' and GR 'theory.

这是显而易见的，他们指的是牛顿'法'的引力而狭义相对论和一般相对论，获得了和气归属'理论'或干脆简论'，躺着的理论。

From 1665 to 1667, has been thinking about Newton's gravity.

1665至1667年间，牛顿已在思考引力的问题。

Chapter 1 is an introduction and overview,outlining the background,motivation and significance.

第二章对规范理论和引力理论对应关系以及量子色动力学的应用作了简短的回顾。

Bao. I think he does not know the : quasar physics at all!: A simple reason: astronomers detected redshifts of quasars based on the spectr : al lines emitted from the emission line regions, which are 0.1 to 1 parsec (1p : arsec=3.26 light years) far away from the central black hole. Therefore there : is very little effect from the gravitational redshift!

观察到的类星体的光可在几日内有明显的变化，可见类星体的发光区大小在光日尺度以下，即使你认为类星体的光谱线产生于吸积盘，那么吸积盘的大小须在光日尺度以下才能不相矛盾，请你说出一个你认定的类星体吸积盘的大小尺度与该尺度内所具有的质量，及因此计算出的可忽略的引力红移。

The analytical method is always used due to the large amount of the objects and not very high accuracy of forecasting. A method based on the position and velocity derived from the mean orbit elements directly is given, which is to avoid the problem of singularity in calculating the periodic terms of orbit elements variation, thus the process and software can be simplified.

在已有分析法得到t时刻平均根数的基础上给出一种轨道预报方法，由t时刻的平均根数给出该时刻卫星的位置和速度，在此基础上将地球非球形引力摄动的周期项直接用卫星直角坐标的位置和速度分量表示，这样可以避免在计算轨道根数变化的周期项时出现的奇点问题，从而对根数的选择无特殊要求，可适用于各种轨道，简化预报程序和相应的软件，提高预报效率。

According to introduction, they make use of Europe south the astronomical observatory establish in 3.6 meters caliber astronomical telescope of the Chile a set of the mountain lodge of 2400 meters saddle type of an elevation, confirm Be located on south the fixed star"Gliese 581" inside the along while ball scales horoscope see toward the speed because it surroundings can't see fixed star of gravitation function but"perturbation" for appear, subsequently reckon this a red and short star neighborhood of"new the Earth" round a mother fixed star of revolution around sun period and quality.

根据行星的介绍，他们利用欧洲南方使用建立天文台3.6米口径的智利一集的山2400米的海拔马鞍型，提出确认将于南部的恒星"格里斯581"所在的内沿，同时对球尺度占星速度见的天文望远镜因为它周围看不到固定的引力作用，但"摄动出现，随后估计这是一个红色的和短期的"新地球"轮明星邻居母亲围绕太阳固定期限和质量革命之星"的明星。

The energy-momentum tensor of gravitational field is a very important physical quantity.

引力场的能动张量是引力理论中一个极为重要的物理量。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
