This paper has given a thorough investigation into the application of BP neural network to gravitational density interface inversion as well as the implementation of wavelet theory in potential field decomposition and, on such a basis, analysed and evaluated the prospect of applying wavelet neural network to the inversion of gravitational and magnetic data.

重磁数据处理是地球探测与信息技术学科中重磁方法、理论在生产实践工作中的重要环节，其中反演问题和位场分离除了具备自身的作用外，两者并不是截然分开的。位场分离可以为反演问题提供更加可靠的先验信息，对提高反演精度具有一定的作用。反演问题是地球物理的核心问题。增

Astronomers led by Fritz Benedict and Barbara McArthur, of the University of Texas, Austin, examined the Earth's nearest known exoplanet neighbour—a gaseous giant orbiting the sun-like star Epsilon Eridani, 10.5 light years away in the constellation Eridanus.

在弗里兹·本尼迪特和芭芭拉·麦克阿瑟带领下，得克萨斯大学的天文学家们探测了一颗系外行星，这是已知的系外行星中离地球最近的一颗。

The Geobiology/Astrobiology group studies of Geobiology and Astrobiology, including elements of the atmosphere, the hydrosphere, and the lithosphere, the limits of life and habitability on our planet, organisms living at unusual conditions, searching for extraterrestrial life, and Mars.

该研究组主要是研究地理生物学和太空生物学，包括大气，水圈和岩石圈的组成，地球上生命的局限性和可居住性，异常环境中的有机生命，搜索地球外生命，以及火星。

However at night it is expected that the nightside and outer magnetosphere is primarily driven by the solar wind as is the case on Earth.

但在夜间，它预计阴面和磁层外，主要是由太阳风主导，是地球上的情况。

But he accepts this model still does not explain how life actually began in the first place.The professor and his late colleague Sir Fred Hoyle championed the so-cllaed "panspermia" theory from the 1960s.

他表示，天文学证据可以绝对支持这一观点，即地球上的所有生命体并非起源于地球，而是来自外太空，虽然我们目前尚不知晓最初的生命是如何产生的，但一旦产生便可在宇宙中繁殖。

The idea that alien micro-organisms could be hiding out here on earth has been discussed for a while, according to Jill Tarter, the director ofthe US SETI project, which listens for signals from civilizations based around distant stars.

The outermost layer of Earth's atmosphere, lying above the thermosphere and extending thousands of kilometers into space, from which molecules having sufficient velocity can escape Earth's gravitation.

外逸层地球大气层的最外圈，位于热层之上，并向太空延展几千公里，在那里分子具有足够的速度可以逃出地球的吸引力

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
