氦气填充的平流层飞艇在临近空间环境中运行，受到太阳辐照，蒙皮温度变化较大。蒙皮的氦气渗透关系着平流层飞艇运行的时间等问题。从理论分析与实验角度得到温度与蒙皮渗透性的关系，通过数值计算平均渗透率，结合飞艇外形及内部压力范围，估算飞艇的寿命。

The stratosphere airship moves in the near space environment, radiated by the sun, the temperature of enve-lope changes a lot, as a result, the penetrability of He changes a lot.The penetrability of He influences the lifetime of the stratosphere airship.This article, analyses the connection of the temperature and the penetrability.The results, such as the shape of airship, the range of pressure and the average penetrability have been showed after numerical calculation, mean-while, the lifetime of the airship is calculated according to the conditions above.
