The gun's rounds are about the same size as a .30-06 hunting rifle's, and it is capable of firing only where the V-22 has been — not where it's going — and only when the ramp used by Marines to get on and off the aircraft is lowered.

这杆枪的射程大致和。30-06的狩猎来福枪相当，并且它只能在V-22所在的地方——不是飞行通过的地方——同时只有在升降板被放下以用于陆战队员们上下飞机时才能够射击。

He and his team believe the design principle could be used to make long term, self-repairing robots that could mend themselves and be used in hazardous situations and on space flights.

他和他的研究小组相信，该设计原理可用于制造长期的可自我修复的机器人。这种机器人可以进行自我调整，可应用于危险环境下和太空飞行中。

Its stealth and supersonic speed allow the Lightning II to fight in high-threat environments that the slower, unstealthy A-10s cannot survive. The F-35 also will be dispatched to low- and medium-threat theaters.

它的隐身及超音速飞行能力使得闪电II可以在低速、无隐身能力的A-10战机所不能生存的高威胁环境下作战。F-35同样可以用于应对中、低威胁程度的战场环境。
