The bright OH masers are excellent probes of different kinds of astronomical objects in the Galaxy and even of distant galaxies, but the difficulties in identifying the pumping mechanisms of these OH masers and modeling them have hindered the application of this excellent probe.

明亮的OH脉泽是探测银河系中各类天体甚至河外星系的极好工具，但是对OH脉泽的抽运机制的鉴别和模拟上的困难使得这个极好工具一直没有得到极好的发挥。

Events such as the naked-eye burst "are cracking away at the simple picture" theorists have assembled over the past decade, says astrophysicist Joshua Bloom of the University of California, Berkeley.

加州大学伯克利分校的天体物理学家乔舒亚·布卢姆指出，在理论学家们利用过去十年的资料所拼凑起来的那幅简单画面中，肉眼可见的爆发事件是不存在的。

The second-order post-Newtonian(2PX) equations of light ray have to be discussed under the recent extension of the DSX scheme which was founded in early 1990 s to discuss a complete first-order post-Newtonian celestial mechanics for N arbitrarily composed and shaped, rotating deformable bodies.

近来相继提出一系列的空间天体测量计划，要求考虑在多参考系中二阶后牛顿部分对光线传播的贡献，也就是说，必须讨论在最近完成的扩展的DSX体系下的二阶后牛顿(2PN)光线方程。

As a subgenre of science fiction-rather than a literal prediction of the future-books about Drexlerian nanotechnology may serve the same function as Star Trek does in stimulating a teenager's interest in space, a passion that sometimes leads to a career in aeronautics or astrophysics.

作为科幻小说的一种类型一而不是只对未来做刻板如实的预言一德莱克斯勒有关纳米技术的作品对激发青少年对宇宙的兴趣方面可与电影&星球大战&相媲美，有异曲同工之妙。这种强烈的热情有时会使青少年选择以航空或天体物理学为自己的终身职业。

C/1998 J1's track along the edge of the C3 field - where distortion is greatest - was problematic.

早期SOHO用在彗星上的天体测量方法还是很&老土&的：用彗星到太阳的方位角和距离来确定坐标。C/1998 J1 的轨迹是沿着C3视场边缘的，因此象差非常大，这就对旧方法造成了大麻烦。

Odd though it sounds, cosmic inflation is a scientifically plausible consequence of some respected ideas in elementary particle physics, and many astrophysicists have been convinced for the better part of a decade that it is true.

尽管听起来很古怪，宇宙膨胀论是基本粒子物理学中一些颇受尊重的观点的科学的似是而非的结果，许多天体物理学家在未来的十年还是觉得它是对的。

Odd though it sounds, cosmic inflation is a scientifically plausible consequence of some respected ideas in elementary-particle physics, and many astrophysicists have been convinced for the better part of a decade that it is true.

尽管宇宙膨胀说听起来有点奇怪，但它是由基本粒子物理学上一些权威观点所推导出的结果，这个结果从科学的角度讲似乎是有道理的，并且在近十年的时间内，很多天体物理学家都相信它是正确的。

The images produced by computer simulations of the galaxy model show unanticipated features and have been the impetus of r further studies by astrophysicists and astronomers.

所产生的图像的计算机模拟显示银河系模型预料的特点，并已研究开发的动力进一步研究的天体物理学家和天文学家。

The horizontal angular distance from a reference direction, usually the northern point of the horizon, to the point where a vertical circle through a celestial body intersects the horizon, usually measured clockwise.

方位角，方位：从某一参考方向测量的地平线的角距离，通常指从地平线北端到通过天体和地平线相交的垂直的圆周上的某一点，一般顺时针测量。

Based on this, the characteristics of related celestial body positions at the occurrence time of the triggered earthquakes are studied. The distribution patterns, which have tidal_triggering physical basis, of lunar_solar ecliptic longitude differences and declinations and zenith distances are obtained.

在此基础上，对受到潮汐应力触发的地震发震时的天体位置特征进行了研究，得到了具有潮汐应力触发物理基础的地震时的月日黄经差、月日赤纬和月日天顶距的分布图像。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
