摘要
航天器推进系统的单机产品的漏率测试往往采用氦质谱真空室检漏法,研究该方法测量结果的不确定度评定具有重要的工程应用价值。本文首先对真空室检漏法的原理进行了分析探讨,并从不确定的基础理论出发系统地研究了氦质谱真空室检漏法测量结果的不确定度评定方法,并结合工作的具体案例给出了评价的具体步骤。
Abstract： Vacuum chamber leak detection method is widely used in the spacecraft components of propellent subsystem. So it is very important to study the uncertainty evaluation of this method. First, the principle of the vacuum chamber leak detection method was analyzed. Second, the method of uncertainty evaluation was studied based on the basic theory about uncertainty. Last, the detailed evaluation steps were given through a case.
