摘　　要：针对填充了等温材料的压力容器在排气过程中产生的温度变化,提出了测量容器内空气温度变化的方法.建立了利用中间停止法测量容器内空气温度变化的数学模型,仿真和实验结果的比较验证了模型的正确性.针对传统的中间停止法提出了缩短测量时间的新方法.结果表明,同等测试精度下,新方法比传统方式在测试时间上缩短90%以上.To measure the change of pneumatic temperature in the pressure tank with stuffed materials,the stop-in-the-middle method is proposed based on developed mathematic model of measuring the change of temperature in the tank.Good agreement between the simulation and experiment results show that the established model is correct.In addition,to shorten the test time,a new approximate fast calculating means is deduced.The results show that the new computational method can save more than 90% of testing time compared to the original one with the same measurement accuracy.
