The pressure behind this shock wave drive的三人稱單數(shù)形式" target="_blank">drives an inward-moving shock wave that heats the ejecta, seen as the aqua cloud. 激波后的壓力驅(qū)使內(nèi)行激波加熱物質(zhì)，也就是圖中淺綠色的云團。
The expanding ejecta drive an outward-moving shock wave that races ahead of the ejecta into the interstellar gas (bright outer rim). 膨脹的拋出物驅(qū)動著外行激波，領先于拋出物沖入星際氣體（明亮的外緣）。
First came the impact, which sent a rain of molten rock into the air and formed an "ejecta" layer for hundreds of miles around. 首先是沖擊，使熔融巖石沖進空中并且在數(shù)百英里周圍形成一個噴出物的層，然后變成海嘯，勞頓說："海浪沖向熔融巖石并且把它帶回到深水"。
In 1994 Hubble began seeing spots brighten in sequence along the central ring: the supernova ejecta smacking into the ring. 1994年哈伯開始觀測到中央環(huán)上一連串的亮點，這代表超新星的噴出物霹靂啪啦地撞上了環(huán)圈。
Searches in the data for impurity clues in the water-ice dominated plumes and surface ejecta are progressing. 科學家持續(xù)不斷的研究這些由水冰主宰的羽狀煙柱及表面噴發(fā)物，來尋找水存在的可能性。
Bright ejecta rays such as these are produced as impacts excavate and eject relatively unweathered subsurface material. 這些放射狀隕石坑產(chǎn)生于天體撞擊濺出的地下物質(zhì)，綿延在遍布隕石坑的水星表面數(shù)百公里。
