该测控系统的高空目标点（子机）由氢气球搭载，根据需要人工放升气球进行高空布点。
This monitoring and controlling system's pick aback planes are carried by hydrogenballoons in order to set up object at high-altitude according to different needs.
飞行器利用机翼上下两面的压力差形成提升力以平稳的在空中飞行，而潜艇在原理上形同海下的热气球，通过调节自身浮力或升或降。
Aircraft use lift from their wings to stay aloft, while submarines operate like underwater balloons, adjusting their buoyancy to sink or rise.
最早的飞行员乘坐“气球”升向空中。
他们越是远离乡土，就越变得像一只离开地面的气球，越升越高，直到它内部的压力使它爆破为止。
The further the army got away from the good Chinese earth, the more did it become like a balloon which, rising from the ground, gets ever higher until its internal tensions cause it to burst.
气球以粘贴、网罩或镶嵌的方式与风筝结合成一体。轻体风筝的静态升重比为0．2―0．8，降低了对放飞最小风力的要求，使放飞活动有更多的机会可选择。
It has a static lift-weight ratio of 0.2-0.8 and thus requires relatively low minimum flying wind force, and this results in more kite flying chance and ever elegant fly effect.
