研究了超高速破片碰撞双层靶形成碎片云的分布特点。

Distributive characters of hypervelocity fragments impacting double-level target were researched.

后面的宇宙飞船随即飞过了碎片云，灰尘被撞击所抛起。 然后，它用仪器分析在它也撞击之前的月球里面有什么。

A trailing spacecraft then flew through the cloud of debris and dust thrown up by the collision and used its instruments to analyze what was inside before it also struck the moon.

美国航天局的科学家曾希望这个撞击会抛起六英里高的月球尘埃和碎片云，通过对其扫描，可以找到结冰水的证据。

Nasa scientists had anticipated that the impact would throw up a six-mile-high cloud of lunar dust and rock which could be scanned for evidence of frozen water.
