| 摘 要： | 日常生产、生活中的小型压力容器因设计缺陷、外力持续作用等因素会出现容器内物质泄漏,从而对环境、生命安全构成威胁,特别是微量泄漏因其表象不显著易被忽略,封闭空间内的长期微量泄漏同样会因有毒、可燃气体体积分数增加而引发安全事故.以最常见的丙、丁烷混合气打火机为研究对象,设计了打火机微量泄漏检测仪,在可燃气传感器输出阻抗与泄...

| Abstract: | Due to design flaws and continuing role of external forces,trace leakage from imperfectly small pressure vessels will occur intentionally or accidentally,which is a big threat to both our life and environment.It is not easily detected for its insignificant appearance,thus tending to be potential safety concerns caused by the increasing of toxic or flammable gas.To solve this problem,a lighter trace leakage detection method and detection instrument based on gas lighter are developed.The model of gas trace le... |
