天体之间的

The angular distance between an imaginary line around a heavenly body parallel to its equator and the equator itself.

某天体赤道与平行于该赤道的天体周围的一条虚构线之间的角距离。

An instrument for measuring the angular distance between celestial objects; resembles an octant.

测量两个天体之间的角距离；类似于八分仪。

A telescope equipped to measure small angular distances between celestial bodies.

量日仪一种望远镜，用以测量天体之间微小的角距离

There would be several conjunctions between the two planets, but none in Cancer as viewed from the Earth.

这期间它们两个天体之间也出现过几次重合，但是没有一次是从地球这个角度看上去处于巨蟹座的时候。

Next, we reviewed the connection between RBLs and XBLs and the energy radiative process of BL Lacertae. Synchrotron radiation from radio to optical band and inverse Compton Scattering in γ ray wavebands are a wide accepted point. The beam model and gravitationally lensed model are two models associated with the radiative process. At present people tends to favor the previous one.

接着我们对射电选BL Lac型天体和X射线选BL Lac型天体之间的关系以及BL Lac型天体的能量辐射机制进行了评述，从射电到光学的同步辐射和γ射线波段逆康普顿散射的观点受到大家的普遍接受，射束模型和引力透镜模型是与辐射机制相关的两种模型，目前比较倾向于射束模型的解释。

Inthis paper, we collect 119 γ-ray-loud Blazar 97 flat spectrum radioquasars (FSRQs and 22 BL Lacertae objects,and investigaterespectively the correlation between the γ-ray emission (maximum,minimum, and average data) at 1GeV and the radio emission at 8.4GHz bydiscrete correlation function method.

收集了119颗有γ射线噪的Blazar天体样品(97个平谱射电类星体和22个BL Lac天体)，用离散相关函数方法分析了1GeVγ射线辐射流量(最大值、最小值和平均值)与8.4GHz射电辐射流量之间的相关性。

The aim is to shoot the orb between the other two.

这样做的目的是为了拍摄两个天体之间的其他。

Five locations in space relative to two bodies where a third, less massive body can maintain a stable orbit around a common center of mass

质量较小的第三天体在两天体之间可能保有围绕共同质心的稳定轨道的点之一，这样的点共有五个

The gravitation between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them.

两个天体之间的引力与它们的质量成正比，而与它们之间距离的平方成反比。

One of the critical point for solving this problem is to effectively identify the pumping mechanisms of known OH masers and find out the physical connections between the masers and the objects bearing these masers.

解决这个问题的关键之一就是在已知的OH脉泽源中有效地鉴别出它们的脉泽抽运机制，并由此找出脉泽特征与产生脉泽的天体之间的物理联系。

China's plan to cut energy intensity by 20 percent and pollutant discharges by 10 percent between 2006 and 2010 is a case in point.

中国计划在2006年到2010间降低20%的能源强度和减少10%的主要污染物排放，就是一个这样的例子。
