气密封性试验中的泄漏测试方法研究

Study on a leakage test method in air-sealed experiments

泄漏测试是材料／结构气密封性试验中经常要遇到的问题。本文在分析传统排水集气方法的基础上,提出了压降 法,详细论述了其测试原理、适用性等,并给出了一个典型的工程应用实例。

The leakage test is frequently an important matter during air-sealed experiment in respect of material/structure. Based on the analysis of conventional draining water gathering of gas law, this paper advances a new pressure drop method and elaborates its test principle and applicability. Subsequently a typical application example of the method is given.
