地球

Also: to extend the bottom of the central vertical bisector, the earth is flat-line, this line is the Earth's mainland and flat into the marine equivalent of two and a half.

还有∶延长在底面中央的纵平分线，就是地球的子平线，这条线正好把地球的大陆和海洋平分成相等的两半。

The motive behind this is unclear, though it has been theorised that they wished to pillage our world for its natural resources. Race X's invasion was a campaign of opportunity, and there have been no instances of Race X activity on Earth since the destruction of Black Mesa, presumably because after the nuclear blast the Black Mesa area was an inhospitable environment, and the Earth as a whole lost its appeal as a target once it was conqured by the Combine.

虽然以推断出它们希望掠夺这个世界的自然资源，但是在此背后的动机是为了核能。X族的入侵是一个战役机会，而且在黑山基地毁灭前并没有X族在地球活动的先例，可能是因为在核爆炸以后，黑山地区变成了不适合居住的环境，作为曾被联合军征服过的目标，地球已完全失去了自身的吸引力。

Circling the globe, the boreal forest—its name derived from Boreas, the Greek god of the north wind—comprises one-third of Earth's wooded lands.

环绕地球，那北方森林――它的命名来自北方之神，希腊神的北部风――包含三分之一的地球的多树林平原。

Circling the globe, the boreal forest-its name derived from Boreas, the Greek god of the north wind-comprises one-third of Earth's wooded lands.

环绕地球的北方针叶林，其名字来源于博瑞艾斯---希腊神话的北风之神，它涵盖了地球上三分之一的森林面积。

Presumably if all life on Earth were extinguished, the Earth's atmosphere would fall back to a persistent equilibrium, and become as boringly predictable as Mars and Venus.

可能要等地球上所有的生命都寂灭之后，地球的大气才会回降至持续平衡状态，变得像火星和金星那样沉闷。

The Earth thus appears to be itself a celestial body; it does not lie at the bottommost position in the center of Ptolemy's (and Dante's) scheme where it is "the dump heap of the filth and dregs of the universe".

因此，地球本身像是一个天体，不必位於托勒密图示最中心的位置，在那儿，地球是「宇宙的残渣与垃圾堆」。

From these results mentioned above, we discussed the anomaly sources of the Bouguer gravity field, the lithospheric rheological properties, the crustal density distribution of the Tibetan

利用所得到的上述一些结果，我们对青藏高原区域布格重力异常源、岩石圈的力学特徵、密度分布等问题进行了讨论，并对其包含的地球物理及地球动力学含义进行了进一步的探讨。

But had Galileo followed the results of his observations to their logical conclusion, he should have backed another system - the Tychonic view that Earth didn't move, and that everything else circled around it and the Sun, as developed by Danish astronomer Tycho Brahe in the sixteenth century.

但是，如果伽利略尊重观测事实并运用逻辑推理，他应该证明的是另一个观点是真确的，即托勒密认为的地球不动而其他星体都围绕地球和太阳做圆周运动，这是16世纪丹麦天文学家第谷提出的观点。

The Brahe theory stated that all of the planets except the earth revolved around the sun, which in turn revolved around the earth. Brahe's assistant, German astronomer Johannes Kepler (1571-1630), used induction to analyze the data collected by Brahe over a twenty-year span. Kepler supported the heliocentric theory by proposing three laws of plant revolution.

在哥白尼思想的影响下，泰革(Tycho Brahe， 1546-1601)在观察的基础上，提出了哥白尼式的地心说︰地球以外的行星都绕太阳转；但太阳及其行星都绕地球转﹗泰革的助手、德国天文学家凯普勒(Johannes Kepler， 1571-1630)用归纳法分析泰革二十年积累的数据，提出了"行星运行三大定律"，支持了日心说。

This earth is ours, it is not the earth of the Brahmin, the Russian or the American.

地球是我们的，它不是婆罗门的地球，俄国人或者美国人的。

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。
