墨西哥发现了一种高灵敏度天然气泄漏检测器,它能在天然气泄漏后的40秒钟内迅速作出反应。据墨西哥尤卡坦科学研究中心专家马尔克斯介绍,这种检测器实际上是一种用既能导电又能与天然气发生反应的聚合物制成的电线,其直径为2毫米。在正常情况下电线导电,但遇天然气后,聚合物与其发生反应而熔化,便出现短路,这样就可立即发现漏气问题。该检测器 Mexico has discovered a highly sensitive natural gas leak detector that can react quickly within 40 seconds of natural gas leaks. According to Marquez, an expert at the Yucatan Center for Scientific Research in Mexico, the detector is actually a wire made of a polymer that can both conduct electricity and react with natural gas and has a diameter of 2 millimeters. Under normal circumstances, the wire is electrically conductive, but in case of natural gas, the polymer reacts with it and melts, causing a short circuit, so that a leak can be immediately detected.
