天体的

In this thesis, the properties of temperature and electrostatic potential energy of neutron star are investigated within the frame of general relativity further.

而它们的高密度和强引力场又使它们的讨论离不开Einstein的广义相对论，成为相对论天体物理十分重要的一个研究方向。

The central cloverleaf is rather light emitted from a background quasar.

中间的苜蓿状的天体实际上是后面的一颗类星体发出的。

The mission will map the entire sky at four infrared wavelengths with sensitivity hundreds to hundreds of thousands of times greater than its predecessors, cataloging hundreds of millions of objects.

该使命采用的4种波长的红外线在敏感度方面比过去的高出上千万倍，通过它能绘制整个太空，对上亿的天体进行归类。

The bright yellow orb in his abdomen represents the full opening of his Solar Plexus chakra, the seat of his will and power.

在他的腹部明亮黄色天体代表，完全打开了他的腹腔神经丛的能量中心，是意愿和力量的所在地。

The Chandra X-ray image shows hot gas in the galaxy and point sources that are a mixture of objects within the Sombrero as well as quasars in the background.

钱德拉拍摄的 X 射线图象显示的是星系中的热气体和点源，后者既有草帽星系内的不同天体，也有背景类星体。

China and the Western Countries have under-gone the same road in the recognition of the shape of the earth:from squareness to roundness .

中西方在对我们居住的这个天体中的大地形状的认识几乎走过了相同的道路，即，先方后圆。

The Chandra data show the shape and extent of the high-energy emission in the central region. By studying W28 and others like it, astronomers hope to better understand the complexities involved when a star explodes in a crowded neighborhood.

钱德拉的数据同时也展现了中心高能发射物形状和程度，通过研究W82和其类似天体，天文学家希望能更好的理解当一颗处于拥挤环境中的恒星爆炸时的复杂性

Narrow Line Seyfert 1s (NLS1s, including high luminosity quasars with similar properties) are very important extrema of type Ⅰ AGNs. The unusualness of NLS1s is very useful to test the viabilities of AGNs models and thus provide a new way probing into AGN phenomena. The ratio of Fe to α-element (e. g., O, Ne, Mg...), Fe/α, can serve as an excellent indicator for constraining the ages of star-forming systems.

Based on the ISC earthquake catalogue data, according to the orbit equations of two-body-problem and the perturbation theory of celestial mechanics, we could determine the projection pole of the sun, and thus calculate the zenith distance from the sun to the epicenter. After calculating all the earthquakes on their zenith distances, we could get the distribution of the solar zenith distance versus the occurring probability of earthquakes.

基于ISC地震记录，利用天体动力学中二体问题的轨道方程和摄动理论，确定发震时刻太阳在地面的投影点位置，并进一步计算出太阳相对震中的地心天顶距，将地震按天顶距的大小进行统计，得到地震的太阳天顶距地震频度分布。

Monotheism, however, prevails over the cosmogonic and ethical dualism because Ahura Mazda is father of both spirits, who were divided into the two opposed principles only through their choice and decision.

然而，一神论胜过天体演化论和伦理上的二元论，因为阿胡玛兹达先于两者的灵魂，只有通过他们的选择和决定才会分开两种相反的法则。

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。
