nasa斯必泽太空望远镜的资料，资料显示这颗明亮的恒星周围环绕着一个尘埃带，其中的物质包含水冰、有机物和岩石，跟碰撞后粉碎的彗星物质极为相似。
NASA's Spitzer Space Telescope showing a band of dust around the bright star that strongly matches the contents-such as water ice, organics, and rock-of a comet busted apart in a collision.
在北半球最近碰撞形成的五个陨石坑掀起的岩屑中，发现了埋藏的冰。
The buried ice was spotted in debris thrown up in five recent northern hemisphere impact craters.
一开始你可能不会这样认为，因为太阳系里和彗星发生过碰撞的行星都比火星还远，在那样的轨道上水永远是以冰的形式存在。
On first blush, you might think not: the planet where the comet or comets came to grief is farther out than Mars, in an orbit where water would be permanently frozen.
该方法的优点是能将冰对结构的碰撞及冰的破碎过程可视化，同时发生碰撞后结构在每一时间步的响应都可计算出来。
Meanwhile, the dynamic response of the structure at each time step after the ice bumping against the structure can be calculated.
另一方面，自行车碰撞事故，路口或交流电动汽车均显着高于相比，冰车。
On the other hand, bicyclist crashes involving HEVs at intersections or interchanges were significantly higher when compared to ICE vehicles.
冰情较严重时，中小型船舶在海冰的作用下容易走锚，造成碰撞、搁浅等严重事故。
Under severe ice conditions, small and medium sized vessels are easy to drag, being caused collisions, groundings and other serious accidents.
在方案中发病率行人碰撞车辆转弯时，显着提高混合电动汽车相比，冰车。
Incidence rate of pedestrian crashes in scenarios when vehicles make turns was significantly higher for HEVs when compared to ICE vehicles.
