3·The company is also dreaming larger, more distant space dreams. This model shows how inflatable structures could be used for a lunar settlement.
毕格罗航空航天公司梦想的已经不仅仅是眼前的空间站了，他们想得更远。图中的这个模型显示了充气式结构将会如何运用在月球定居点上。
4·The idea of inflatable spacecraft is not new. The Echo I - NASA's first communication satellite - was essentially 100-foot-wide Mylar balloon that reflected radio transmissions from the ground.
充气式航天器并不是什么新颖的想法，NASA的第一颗通讯卫星回声1号实际上就是一个宽30米的聚酯薄膜大气球，它是用来发射来自地面的无线电广播的。
5·Inflatable devices that fit around children's waists or arms are toys and shouldn't be regarded as reliable flotation devices, added Nathalie Vallieres, of the Lifesaving Society.
另外，充气式的设备，比如游泳圈或臂圈，只是玩具，不能把它们当做是可靠的救生设备，救生协会的娜塔莉·瓦利尔还补充说明：“这些设备很容易被扎破或者移除掉，这样便提供不了充足的浮力保证孩子的安全。”
