1·Needing someone is just like needing a ballute.

需要某个人就像需要一顶降落伞。

2·The ballute is internally provided with a soft intake pipe which is connected with the compressed air chamber in the truck.

气伞内置软状进气管，与车内压缩空气室连接。

3·The ballute consists of a ballute cover and ropes, and the ropes are respectively connected with the sliding axle in the chute and the pull rod in the semicircular arc-shaped pull rod bracket.

气伞由伞罩、绳索组成，绳索分别与滑槽内滑动轴和半圆弧形拉杆架内拉杆连接。
