多年来管道工业一直在努力开创新型气体泄漏检测系统，其他行业包括化工、造纸、冶金、制造、微电子。军事／航天等也有同样的需求。在不同的应用范围，泄漏量小至每年几十克，大至每小时几十立方米。目前采用的高技术手段有声测试，电化学传感、激光吸收及各种检漏器。一种称? Over the years, the pipeline industry has been working hard to create new gas leak detection systems. Other industries include chemicals, paper, metallurgy, manufacturing, and microelectronics. Military / aerospace also have the same needs. In different application areas, leakage is as small as tens of grams per year, ranging from tens of cubic meters per hour. Currently used high-tech means audible testing, electrochemical sensing, laser absorption and a variety of leak detectors. A
