摘　　要：介绍了气体注入压力激励方法测量卫星液体推进剂剩余量地面模拟试验 ;给出了包括温度、压力变化特性 ,采样数据选择 ,试验结果等方面的详细情况 ;常规模型模拟测量结果表明 ,可以实现不确定度小于贮箱总体积 1 .0 %的高精度测量。The ground simulation test for gauging liquid propellant remaining on a satellite is introduced.The test results obtained from the isothermal model are presented in details,mainly including the transient characteristics of the pressure and temperature,the measurement accuracy and its relation with other factors.The possibility that the accuracy is better than 1% of the total tank volume is indicated,and some related problems are discussed.
