太阳系

Carbon has two non-radioactive isotopes, and in material from the solar system, including most meteoritic minerals, these are mixed in a well-known ratio.

碳有两个非放射性的同位素，在太阳系的物质中，包括在大多数的陨石矿石中，它们的混合比例是众所周知的。

IDL interface to JPL/SPICE - spice-dlm provides a seamless mechanism for IDL users to access the SPICE library from JPL/NAIF, providing ephemeris information for solar system objects and spacecraft.

spice-dlm为IDL用户提供了一个无缝的机制以从JPL/NAIF中访问SPICE库，它提供了有关太阳系中的天体和太空船的星历信息。

In the General History of Nature and Theory of the Heavens (1755), Kant laid out the Nebular hypothesis, in which he deduced that the Solar System formed from a large cloud of gas, a nebula.

在《宇宙发展史概论》中，康德提出了&星云假说&，认为太阳系源自一大团气体星云。

Millisecond time scales in the X-ray light curve of Scorpius X-1. The estimated sizes of these occulting TNOs are about or less than 100 m. This is the first time that TNOs of such a small size are detected. Our discovery of the X-ray occultation demonstrates a new method to study smaller TNOs.

所以，我们在这里介绍了我们利用X-ray波段的掩星方法，藉由利用RXTE卫星观测天蝎座X-1的数据，在毫秒尺度找到了一些可能的X-ray掩星事件，而这方法将可让我们了解一些大小在100公尺左右或更小的物体的分布情形，而这也是我们第一次在X-ray波段所发现掩星事件，而这方法的持续研究将能让我们对於太阳系的形成会有更多的帮助，因次在此提出来和大家分享。

Meteorite impact is one of the important agents that caused the palaeoclimatic environment catastrophe and the extinction and rebirth of creatures in the geologic history during the evolution of planets and satellites in the solar system, and it is also the very common event during the nonage evolution of the earth.

陨星撞击是太阳系各行星及卫星演化、地质历史中导致古气候环境灾变与生物灭绝和新生的主要营力之一，在地球演化早期是一种较为普遍发生的事件。

Bacteria or their spores can probably survive the journey through space,despite the cold and intense radiation,which means that primitive life might once have been carried between the planets of the solar system,an idea called panspermia.

细菌或其孢子可能从空间旅程中生还，尽管有低温和强烈的辐射，这意味着原始生命有可能曾在太阳系的行星之间转移，这个想法被称为胚种论。

Aimed at explaining the processes which caused such an enormous hydrogen concentration in the Earths core,an unconventional petrological model of the origin and evolution of the Earth,other planets and the Solar system as a whole is suggested in this paper.

为了解释这些导致地球内核如此巨量氢集中的作用，文中提出了一个关于地球、其它行星及作为一个整体的太阳系，其起源与演化的非传统的岩石学模型。

This site, by Larry Nittler of the Carnegie Institution of Washington, gives an overview of the study of presolar grains in meteorites.

该站点介绍了在太阳系形成以前时的红巨星和超新星粒子，这些粒子通过陨石来收集到，该网页是由美国华盛顿卡内基学会Larry Nittler先生创建的。

Some hypothesize that the Moon was formed in the same way as were the planets in the inner solar system (Mercury, Venus, Mars, and Earth)—from planet-forming materials in the presolar nebula.

有些理论家假设，月亮是以太阳系内侧行星（水星、金星、火星、及地球）相同的方式形成的——从前太阳星云内能够形成行星的材料中发展而来的。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
