查询词典 outer planets

The Jovian planets are all large and have low mean densities, indicating they are composed of lightweight gases such as hydrogen and helium, as well as frozen compounds such as ammonia and methane.

木星类行星都有体积大密度小的特征，这表明他们成分构成不仅包括冻结复合物，如氨和甲烷，还包括重量轻的气体，如氢和氦。

High-pressure studies of hydrogen, helium, planetary ices, and clathrates are revealing secrets hidden within the vast interiors of Jovian planets and satellites, as well as providing new solutions for energy and environmental issues.

对氢、氦、行星冰及笼形包合物的高压研究不仅有助于揭示掩藏在巨大的木星及其卫星的内部信息，而且有可能为能源和环境问题提供新的解决方案。

Using a technique known as interferometry, the Keck will study dust clouds around stars where planets may be forming.

运用一项被称作干涉测量法的技术，Keck将研究可能形成行星的恒星周围的气体尘埃。

If the nearer star has orbiting planets, keen-eyed observers can spot the subtle clues of their presence in the magnified light.

如果距离较近的恒星存在环绕的行星，目光尖锐的观察者能通过放大的光来发现行星的细小线索。

Kepler's laws of Newton discovered the law of gravitation 10000 l ^ D has laid the foundation, then to the law of gravity, in turn, amended the third Kepler principle, namely, the ratio of 32 to strictly say no is a constant with the planets related to the quality of the l ^ D.

开普勒定律为牛顿发现万l^D有引力定律奠定了基础，而后，万有引力定律反过来又修正了开普勒第三定律，即比值32严格说不为常数而与行星l^D的质量有关。

IYA2009 also celebrates the work of Johannes Kepler, a German astronomer who published Astronomia Nova in 1609. The groundbreaking work was the result of a decade of research on the movement of planets in our solar system. Kepler's models ─ known as Kepler's Laws of Planetary Motion ─ are still used by astronomers today.

此外，国际天文年也同时庆祝克卜勒的成就，这位德国天文学家在一六0九年出版《新天文学》一书，这本划时代的开创性巨作是克卜勒耗费十年研究太阳系星球运行的心血结晶，被称为克卜勒定律的「克卜勒行星运转定律」，至今仍然备受天文学家遵循。

If all goes well Kepler will leave us with a catalogue of planets that could support life.

如果一切顺利，那么开普勒号将为我们找到一系列可能存在生命的行星。

In fact, the planets Kepler has found so far are significantly larger than Earth.

实际上，开普勒目前已发现的行星，个头都明显比地球要大。

On the other hand, if those planets are rare, Kepler might find none.

但另一方面，如果这一区域类地行星很罕见，"开普勒"也可能一个都发现不了。

Kepler, by contrast, can find such planets easily.

相比之下，开普勒可以很容易地找到这样的行星。
