摘　　要：采用聚乙烯醇(PVA)作为凝胶剂制备了硝酸羟胺(H AN)水凝胶,并开展了长贮实验研究其贮存性能。结果表明,敞开体系下H AN水凝胶长贮后有液体析出,析出液中含H AN,而在温度40℃以下密封长贮后无液体析出,燃烧性能变化不明显。因此,H AN水凝胶应密封贮存且贮存温度不超过40℃。Long term storage experiment was conducted to analyze the storage performance of hydroxylammonium nitrate（HAN） hydrogel which was made from polyvinyl（PVA） as gel agent.There was precipitation liquid which contains HAN under the open system,while under sealed condition,this phenomenon of precipitation liquid did not occur and the combustion performance of HAN hydrogel did not change significantly.Results show that HAN hydrogel should be storied under sealed condition and the temperature should not exceed 40 ℃.
