The hot-air balloon took off. It was as buoyant in the air as a rose leaf in water.

根据"就像水中的玫瑰叶"这样的比喻可知，buoyant是"飘浮的"之意。

The balloon moves through the air, and measures the temperature gradient of ambient air, called the ambient lapse rate, the environmental lapse rate, or the prevailing lapse rate.

气球在空气中移动穿行，测量周围空气的气温，叫做四周垂直递减率，或环境递减率或普遍递减率。

The 2 Montgolfier brothers, Joseph and Etienne, first began experimenting with paper vessels elevated by heated air, and after a couple years of experimentation they developed a hot air balloon similar in design to the ones used today, but with one major difference — they were powered by burning straw, manure and other material in an attached fire pit instead of propane.

2孟格菲兄弟，约瑟夫和Etienne，第一次开始尝试与纸张的船只通过加热空气升高，实验后，他们制定了一个热气球在设计上类似今天使用的一对夫妇年，但有一个最大的不同-他们是焚烧秸秆，粪肥和其他物质动力，而不是在一个丙烷重视跳火坑。

The pilot uses the propane burner to control how high or low the balloon flies. To go up, he or she turns up the burner to make the air in the envelope hotter. To go down, the pilot just lets the air cool down.

驾驶员会通过丙烷燃烧器来控制气球飞的高度，想要飞高时，他或她就会打开燃烧器加热气囊内的空气，若想要降低高度时，驾驶员只要让空气冷却下来即可。

As it opens, the pilot uses a propane burner to blow hot air into the envelope. The balloon then rises as it is inflated with the hot air until it is upright.

当气球充好气后，驾驶员会使用丙烷燃烧器将热气灌入气囊，当热空气渐渐增加，气球会慢慢的上升，到最后会完全竖立起来。

The subjects breathed through an oronasal mask and one-way ale. Expired air was collected in a 5-l balloon in order to proide adequate mixture of dead space and aleolar air.
