摘　　要：为了优化固定工艺在航天应用过程中对多层隔热组件的漏热影响,通过加强实验的方法测试了3种不同的固定方式:尼龙搭扣固定、不锈钢螺钉固定和聚酰亚胺螺钉固定的多层隔热组件在高真空环境下的隔热性能。实验结果表明:在相同的实验条件下,尼龙搭扣固定的多层隔热组件的漏热量小于聚酰亚胺螺钉固定的多层隔热组件,而聚酰亚胺螺钉固定的多层隔热组件的系统漏热量小于不锈钢螺钉固定的多层隔热组件。In order to optimize the effect of fixed process on the performance of multilayer insulation（ MLI） in the process of space application,three different fixation were tested by the method of strengthening experiment. The heat insulation performance of three different MLI with different fixed modes in high vacuum environment is tested. The experiment results show that under the same experimental conditions,the heat leakage of MLI with polyimide screw fixation is larger than that with nylon clasp fixation but srnall than that with stainless steel screw fixation.
