摘　　要：研究高空气球升空前后的体积变化情况,对于平流层高空气球的总体设计具有重要的实用价值。文章基于一系列基本假设,采用理论方法研究了平流层高空气球在升空过程中体积变化情况,并通过有限元方法对理论计算结果的合理性进行了验证。结果表明该理论方法具有较强的实用性,对于高空气球尺寸设计具有重要的指导意义。Research on the volume variation of high‐altitude balloon before and after the ascending is of great importance to stratospheric balloon design .Based on a series of basic hypotheses ,the volume variation of stratospheric balloon during the ascending process is investigated by using the theoretical method ,and the rationality of theoretical calculation results is verified by finite element methods .The results show that this theoretical method is practical and can play an important role in the size design of high‐altitude balloons .
