天文

Maya also built some astronomical observatory, we can figure out the moon and planets eclipse and operation cycle time.

玛雅人还建造了一些天文观测，我们可以计算出月球和行星的运行周期和月食的时间。

A third globular cluster, M80, is to the right of Rho Ophiuchus.

The otherworldliness and remoteness of the area add to the adventure of conducting cutting-edge astronomy.

现在，这个偏远的蛮荒之地，已经成为天文尖端探测的要地。

More importantly, there is additional function that will overlay maps, charts and user guides onto the night sky, describing in detail each identified astronomical objects including famous constellations such as Orion, Andromeda and Cassiopeia.

更重要的是，额外的功能，将重叠的地图，海图和用户指南上夜空，详细说明了每一个确定的天文物体，包括著名的星座，如猎户座，仙女座和仙后座。

The author discussed the effect of opacity on stellar evolution and concentrated on the mechanism of triggering blue loop by using Padova stellar model. It shows that extended mixing at the bottom of the convective envelope changed the interior hydrogen profile, which triggers or suppresses blue loop. Laboratory astrophysics, which is a cross subject of astrophysics and plasma physics, combines the demand of accurate data of radiative opacity with the latest advances in high intense lasers to devise the third independent method to study the radiative opacity. On the basis of the comparison between stellar material and laser-produced plasma in terrestrial laboratory, the desirable way to study opacity in laboratory and the brief introduction to the experiments relative to opacity are given.

本论文就开展辐射不透明度实验室研究的背景、内容和意义进行了介绍，并在对实验室的激光等离子体和天体环境下的恒星物质两者差异和相关性的认识基础上，论证了开展辐射不透明度实验室研究的可行性，而且对世界上正在开展的类似研究予以简要介绍，期望可以将天体物理领域对辐射不透明度数据可靠程度的质疑以及对其准确数值的广泛要求，与激光等离子体物理实验的最新进展相结合，推进辐射不透明度实验室研究，为辐射不透明度的研究开拓了继天文观测和理论计算的第三种独立的手段。

This surface works a bit like a giant radio telescope dish in reverse: Rather than focusing parallel astronomical light rays to a point, it collects the scattered plasmons emerging from a tiny sample--positioned strategically near the mirror--and redirects them into a plasmon "beam" in the metallic plane.

这个表面的工作原理相当于一个倒置的巨型射电望远镜的盘面，不同于天文望远镜把平行的天体光线会聚到一点，这一设计起到的作用是收集从一个位置恰好位于像点的微小样品散射出来的等离激元，并把他们重定向成金属平面上的一个等离激元束。

To try to understand the physical nature of an astronomical phenomenon, one must try to understand its parentage.

在试图了解一个天文现象的物理本质时，人们必然要力图弄清楚它的渊源。

To try to understand the physical nature of anfastronomical phenomenon, one must try to understand its parentage.

From the ground, it resembles a person's head surrounded by a parka hood. In 2000, the Hubble Space Telescope produced this image of it.

从地面上看，它就像一个戴着皮帽子的人头。2000年，我们可以从Hubble天文望远镜中看到这一景象。

The top layer in princely date is pensile a few meters high ship sail, wave with the wind dance, evil spirit it is good-looking, in board carrying a layer on the head view scene has astronomy binoculars and travel binoculars, still have outdoor beer, taste beer view scene here, amorous feelings is provided alone.

在王子号的顶层悬挂着几十米高的船帆，迎风飘舞，煞是好看，在顶层甲板观景有天文望远镜及旅游望远镜，还有露天啤酒吧，在这里品啤酒观景，风情独具。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
