不同海拔地区发射药安定性试验数据差异分析

Variance Analysis of Propellant Stability Test Data in Different Elevation Areas

按照同一试验方法，同一发射药分别在高原地区和内陆地区两地进行安定性试验对比。结果表明：同海拔高差测得的CO2体积分数差别为36％左右。因此，在对不同海拔地区发射药安定性试验数据进行处理时，需考虑气压因素影响，进行气压校正。

The tests of the identical propellant are carried out in the plateau region and inland region with the same test method, the result shows a difference of about 36% in the co2 content in the two regions. So, the atmospheric pressure factor should be considered when handling the data of the stability test from different elevation regions and correction of the atmospheric pressure is necessary.
