摘　　要：本研究开展了氙气低温特性试验,以获得氙气的基本物理性质。在试验温度和压力范围内,氙气压力随温度的变化符合理想气体状态方程。由温度-压力拉偏试验可以归纳出,当温度≥-110℃、压力<10kPa时氙气不会液化。进一步开展的静态和动态条件下的数值仿真计算显示,无论是在静态还是动态条件下,氙气的压力随温度线性的变化基本是线性的。In this study, the low temperature characteristics of xenon were tested to obtain the basic physical properties of xenon. In the range of test temperature and pressure, the change of xenon pressure with temperature conforms to the ideal gas equation of state. It can be concluded from the temperature pressure pull offtest that xenon will not liquefy when the temperature is ≥-110 ℃ and the pressure is<10 kPa. Further numerical simulations under static and dynamic conditions show that the pressure of xenon varies linearly with temperature, whether under static or dynamic conditions.
