摘　　要：漏率是低温绝热压力容器的主要技术指标之一。准确测量漏率值是产品绝热性、可靠性和安全性评估的重要手段。从辅助真空系统设计、检漏系统有效最小可检漏率的分析、检漏仪连接位置和示漏气体的反应时间等几个方面对低温绝热压力容器检漏系统进行了论述与分析。Leakage is one of main technical parameter for cryo-insulation pressure vessels. Measuring leak rate accurately is an important method to assess property, reliability and safety of products. In this paper, impacts of auxiliary pump, analysis of effective minimum detectable leak rate, leak detector, standard leak position and tracer gas response time for the eryo-insulation pressure vessels are discussed and analyzed.
