美国最近发明了一种称之为“越高技术蓝皓锆石”，它可以与石油混合，慢慢冷却火区周围的沙石、油管等，比传统的灭火剂便宜得多。 英国Ａｐｏｌｌｏ公司研制成功一系列模拟量可寻址火灾探测系统。在该系统中，每只探测器本身具有自动处理能力。使用该探测器的控制盘配合环境条 The United States recently invented a so-called “higher technology blue Hao zircon”, it can be mixed with oil, cooling slowly around the fire area sand, tubing, etc., much cheaper than the traditional fire extinguishing agent. British Apollo company successfully developed a series of analogue addressable fire detection system. In this system, each detector has its own automatic processing capabilities. Use the detector’s control panel with the environmental bar
