1.小行星带
1.the region in the solar system between the orbits of Mars and Jupiter, approximately 2.0 and 3.5 astronomical units from the Sun, in which most of the asteroids orbit
2.a region of space where the density of asteroids is high, located between the orbits of Mars and Jupiter
1.Astronomers have long thought that the asteroid belt is being ground down through collisions, but such a smashup has never been seen before.
长期以来天文家们推测小行星带会因为碰撞而粉碎但类似的景象以前从未被观测到。
2.Asteroids are minor planets, most of which circle the sun in a region known as the asteroid belt, between the orbits of Mars and Jupiter.
小行星是较小的行星，它们中的大部分在火星和木星轨道间的小行星带中环绕太阳运行。
3.After a year of studying Vesta, Dawn is scheduled to leave orbit and, in 2015, approach the only asteroid-belt object that is larger: Ceres.
一年后，黎明号探测器将离开灶神星的轨道，计划在2015年到达谷神星，它是小行星带中唯一一颗比灶神星大的小行星。
4.Dodge being hit in an asteroid belt, and get ready to land as you approach a deserted moonscape.
道奇被击中的小行星带，并准备好土地作为你的方法一个荒芜的月球表面。
5.At first, astronomers thought it might be a so-called "main belt comet" --a rare case of a comet orbiting in the asteroid belt.
起先，天文学家们认为这种景象不过是所谓的“主带彗星”——即较为少见的轨道在小行星主带内的彗星。
6.the bodies in the asteroid belt would have also agglomerated into a planet if not for the disturbing influence of Jupiter's gravity.
若不是木星重力的干扰，小行星带里的天体也会集块形成行星。
7.Unfortunately, Mars spent its youth in a bad neighborhood near the asteroid belt and, being small, was especially susceptible.
不幸的是，火星年轻时所处的环境欠佳，不但靠近小行星带，而且本身体积小，所以特别容易受影响。
8.Try the Asteroid Belt sample and Fish Tank sample on the test drive site to see hardware accelerated Canvas in action.
在体验站点上使用一下小行星带例子和鱼缸例子，了解一下硬件加速的Canvas的实践运作。
9.Most meteorites originated within the Asteroid Belt between Mars and Jupiter, and were once part of a planet or large asteroid.
大多数陨石起源于火星和木星之间的小行星带，一旦一颗行星或大小行星的一部分。
10.Because a few dozen of the meteorites that have fallen to Earth come not from the asteroid belt but from Mars.
因为有几十块落入地球的陨石不是来自于小行星带，而是直接来自火星。
