天文学的

Many physics students come to introductory college physics having already taken physics in high school. But Astro 101 students are mostly nonscience majors with little prior knowledge of the basic concepts of light and spectroscopy.

很多前来学习基础大学物理的学生在中学时已经学过物理学；而天文学101的学生大都是非理科专业的大学生，他们以前不了解光和光谱学的基本概念。

"Mysterious ice grain " Pluto once was fully favoured by "constellation fan " and uncounted astrophil, unfortunately "greatly "be laid-off" in reducing the staff the solar system", on August 24 , 2006 late in nearest once, the representative at the meeting takes it as an excuse that "whose insufficient big prepare a track and adjacent to mass planets part coincides ", unanimous decision "gives Plutonian planet qualification the sack", and demotes the person for average short planet on international astronomy federation annual meeting holding in Prag.

By construction, all of these methods require Nyquist-rate sampling of received signals to estimate a small number of DOA's in angle space, which is very expensive in some applications such as radar or radio astronomy.

通过构建，所有这些方法都要求接收信号的奈奎斯特率取样来估计角度空间的小数量的DOA，这在像雷达或射电天文学之类的某些应用中是非常昂贵的。

Foremost among the techniques used to study dense interstellar region is molecular radio astronomy, a relatively new and rapidly developing interdisciplinary science

在用来研究高密星际区域的技术中，最重要的是分子射电天文学；这是一门较新的发展迅速的边缘科学。

As a next step I searched the web for a reasonable astronomy program for my PC and downloaded free trials on several, including Distant Suns, ECU, Sky Chart and Sky Map.

作为下一个步骤我搜索了我的电脑和免费下载的审判程序合理天文学上的网页数，包括遥远的太阳，欧洲货币单位，天图和天图。

Equal consciousness has the fundamental status in the political conscious civilization, but it also play an important part in the constructing of socialistic political civilization . In the political institutional civilization, this paper set forth the issues of the constructing of democratic system, that is, democracy is as important to the constructing of political civilization as the solarism to astronomy. But in the modern society of China, which has the profound tradition of civilianism, what kind of democracy do we need?

平等意识在政治意识文明中具有基础地位，而它对于社会主义政治文明建设具有十分重要的作用；政治制度文明中阐述了民主制度建设的问题，民主对于政治文明建设的重要就象太阳中心说对于天文学一样，然而，在有着深厚民本主义传统的现代中国社会，我们究竟需要怎样的民主？

It was soon recognized that this same data might be scoured for other signals of value to the astronomy and physics community.

很快的，这些分析的数据被认为可能是对天文学和物理社区的另外一种有价值的信号。
