最近,日本研究成功一种地震自明灯.只要地震达到里氏四级,这种自明灯便会发出荧光.地震自明灯使用干电池为电源,和手电筒一样,即可挂在墙壁上使用,也可手持照明.在深夜黑暗环境里,忽然发生地震,地震自明灯自动明亮,即可作为报警信号.又可照明,能消除黑夜地震发生时的慌乱和避免一些意外事故. Recently, Japan successfully studied an earthquake self-illuminating lamp that emits fluorescent light as soon as the earthquake reaches the Leeb 4. The self-illuminating light uses a dry battery as a power source and can be hung on the wall just like a flashlight. Hand-held lighting In the late-night dark environment, sudden earthquakes, earthquakes since the lights automatically bright, can be used as a warning signal, but also lighting, to eliminate the night when the earthquake panic and avoid accidents.
