| 摘 要： | 主要研究低压环境下,压力、温度对氮气和氧气分别在航空煤油中溶解度的影响。实验装置包括除气装置、吸气平衡装置以及称重装置。由实验结果可知：压力在0MPa～0.1MPa,温度为293.15K,303.15K,313.15K时,氮气和氧气分别在航空煤油中的溶解度与压力呈线性关系、与温度呈非线性关系;氮气在航空煤油中的溶解度受压力的影响比氧气的小,受温度的影响比氧气的大;氧气在航空煤油中的溶解度比氮气的大。

| Abstract: | The effect of pressure and temperature on solubility of N2 and O2 in the aviation kerosene was measured in the low-pressure environment.Experimental facilities are composed of a degassing device,an inspiratory equilibrium device and a weighing device.According to the result of the experiments,the solubility of N2 and O2 in the aviation kerosene displays a linear relationship with pressure,while the solubility of both in the aviation kerosene displays a nonlinear relationship with temperature.Compared to oxygen,the solubility of nitrogen is less affected by pressure,but more affected by temperature.Further,the solubility of O2 in the aviation kerosene is greater than that of N2 under the same conditions at 0 to 0.1MPa and 293.15K,303.15K,313.15K. |
