天体的

The team has chosen two very different alien environments in which to place their extraterrestrials, aurelia and blue moon.

为此，研究小组选择了两个完全不同的环境作为外星生物的"家"。它们分别是"奥里里亚"和"蓝月亮"——由计算机模拟出的两个可能在银河系中存在，并可能孕育生命的外星天体。

The main component of the celestial globe is a hollow bronze globe, with crisscross grids on the spherical surface, which are used to delineate the exact position of celestial bodies.

整个铜球可以绕一根金属轴转动，转动一周代表一个昼夜，球面与金属轴相交于两点：北天极和南天极。两个极点的指尖，固定在一个南北正立着的大圆环上，大圆环垂直地嵌入水平大圈的两个缺口内，下面四根雕有龙头的立柱支撑着水平大圈，托着整个天体仪。

At that time, however, nonlinear differential equations had no universal solutions and some problems of celestial mechanics were still required to be resolved.

而非线性微分方程没有普遍解法以及一些天体力学问题的未决，促使庞加莱在微分方程求解过程中引入定性思想，创立了常微分方程实域定性理论这一新分支，突破了原有的微分方程求解的思维束缚，是微分方程研究历史上的一次重大飞跃。

But more precisely, a constellation is a particular section of the celestial sphere that includes all celestial bodies within it.

"Constellation"-星座常常理解为在地球上观察到恒星呈现出的自然形态所形成的模式，但是，更准确的说，星座是一个天球的特殊部分，这个天球包涵了所有天体。

The nautical techniques of Zheng He's fleet and Columbus' fleet, including their taking a ship's bearings, celestial navigation, meteorology and knowing wind, manipulating sail and using wind, compass and it's rose, nautical chart and map, log and measuring speed, sounding channel and so on, had reached the highest level in the sail time.

郑和船队和哥伦布船队的航海术，包括测定船位术、天体导航术、气象识风术、操帆驶风术、罗盘罗经术、海图地图术、计程测速术、航道探察术等等，都达到了帆船时代迄当时为止最高的水平。由于哥伦布的远航比郑和远航晚了八十多年，故哥伦布的航海术较之郑和又前进了一步。

The-in order to get to situations where those equations don't work, we have to consider very extreme astrophysical or cosmological limits.

的，为了获得这些方程的情况下不能正常工作，我们就必须考虑非常极端的天体物理学或宇宙的限制。

In this context, the research and instruction of mathematics—which, as established by Christophorus Clavius, teacher of Matteo Ricci, included geography and cartography—constituted a process of spiritual elevation, a journey toward salvation.

在耶稣会士于1551年建立的罗马学院中，来自整个欧洲的学生除了学习神学以外，还接受着高强度的学术培训，学习修辞学、记忆法、哲学，以及数学，包括算术、几何、透视、宇宙学、地球体学、天文制表、天体观测学（后四者可称作 sphaera ），还要学习计时学、音乐、力学、水文地理学和建筑学。

Designated 2005 FY9soon after its discovery by a team led by Mike Brown in 2005, the outer Solar System orb was recently renamed Makemake for the creator of humanity in the Rapa Nui mythology of Easter Island.

Mike Brown带领的小组在2005年发现了它之后，就把它命名为2005FY9，最近这颗外太阳系天体才以复活岛的神话中人类的创造神Makemake名字来重新命名。

A friend of mine called Derek, who is a major astrophysics nerd, has a theory that all the antimatter in the cosmos ended up in Huddersfield in Northern England, but I think that was just because it was a wet Sunday and there was nothing to do.

我的一位朋友称德里克，谁是主要的天体物理学nerd ，有一个理论，所有的反物质在宇宙中结束了哈德斯菲尔德在英格兰北部，但我认为，只是因为这是一个湿星期日及有无关。

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。
