| 1. | The pressure behind this shock wave drives an inward - moving shock wave that heats the ejecta , seen as the aqua cloud 激波后的压力驱使内行激波加热物质,也就是图中浅绿色的云团。 |
| 2. | The expanding ejecta drive an outward - moving shock wave that races ahead of the ejecta into the interstellar gas ( bright outer rim ) 膨胀的抛出物驱动着外行激波,领先于抛出物冲入星际气体(明亮的外缘) 。 |
| 3. | In the case of n132d , the horseshoe shape of the remnant is thought to be due to shock waves from the collision of the supernova ejecta with cool giant gas clouds 在n132d中,遗迹的马蹄铁状外观据信是因超新星抛出物与巨大的冷分子云相撞所致的。 |
| 4. | First came the impact , which sent a rain of molten rock into the air and formed an " ejecta " layer for hundreds of miles around 首先是冲击,使熔融岩石冲进空中并且在数百英里周围形成一个喷出物的层,然后变成海啸,劳顿说: "海浪冲向熔融岩石并且把它带回到深水" 。 |
| 5. | The clear separation of the shocked matter and the heated ejecta in the chandra image allowed astronomers to determine the mass and composition of the ejecta 在钱德拉的照片上,激波扰过的物质与被加热的抛出物之间明显的分隔让天文学家可以定出抛出物的质量与组分。 |
| 6. | If they are correct , it ' s possible , says lawton , for fossils of organisms that were killed by the impact event to be reworked out on the ancient sea floor and laid down on top of ( after ) ejecta 如果他们是正确的,劳顿说,生物体的化石受冲击影响而毁坏,出现在古老的海底的喷出物中。 |
| 7. | In the only other supernova remnant ( the vela supernova remnant ) where such features have been observed , the crescent shapes are clearly produced by ejecta fragments 其他超新星遗迹中,只有一个(船帆座超新星遗迹)观测到了这样的特征,可以确信,该遗迹的新月形外观是抛出的碎片造就的。 |
| 8. | This and the x - ray spectrum , which exhibits a high concentration of iron atoms relative to oxygen and silicon , convincingly show that the ejecta are the remains of an exploded white dwarf star 这幅图连带x射线光谱(显示出了铁相对氧与硅的高度集中)令人信服地说明,抛出的物质是爆发白矮星的残余。 |
| 9. | They attacked different ecosystems in different ways on different timescales , ranging from days for reentering ejecta to months for dust in the stratosphere to years for sulfuric acid aerosols 它们以不同的方式与时间尺度影响不同的生态系,例如,喷出的碎片只要数天就会降回地表,平流层的烟尘要花数个月,硫酸雨雾则要数年。 |
| 10. | There are things like burrows in some of the sediments found in layers above ( after ) the impact ejecta which can ' t easily be mimicked by a flood and imply many organisms survived the meteor impact to die off about 300 , 000 years later 在一些冲击物中有类似洞穴的东西存在于冲积沉淀物的层面内,暗示了很多生物体经历流水影响之后幸存到大约30万年以后才消失。 |
