摘　　要：针对汉代典籍中的“鸡蛋热气球”原理,提出了鸡蛋膜热气球的猜想。结合航空专业本科生教学,组织展开了一系列“鸡蛋热气球”的理论分析与实验工作。结果发现,鸡蛋膜热气球在加热空气时无法升空,但在约3.3 m/s的上升热气流下,却是可以起飞的。本次教学实践活动结合航空科技史探究,激发了同学们的专业兴趣,也锻炼了他们的创新实践能力。The egg-intima conjecture was proposed regarding the“egg hot-air balloon”described in Han Dynasty classics.A series of theoretical and experiment work on“egg hot-air balloon”were organized and carried out during teaching practice for aviation college students.It was found that hot-air could not lift the egg-intima balloons.However,it can take off under an upward hot-air flow of about 3.3 m/s.This present teaching practice,focusing on aviation history,has effectively stimulated the students'professional interest,and also exercised their innovative and practical abilities.
