在消防新装备展览上,一条闪着荧光的绳索吸引了观众。这是“夜光照明导向绳”,能够在黑暗的环境中用来照明,且可以和普通绳索一样使用。这是科学家向萤火虫学习的又一个新成果。萤火虫经过一系列复杂的生物化学反应发出的光,温度不超过0．001℃,是真正的“冷光”。我国对冷光的利用,早在明朝就开始了,渔民利用“萤光”捕鱼就是例子。 At the new display of firefighting equipment, a flickering rope attracted the audience. This is a “lighting guide rope” that can be used in dark environments and can be used like ordinary ropes. This is another new achievement that scientists have learned from fireflies. Firefly emits light through a series of complex biochemical reactions, the temperature does not exceed 0.001 °C, is the real “cold light.” The use of cold light in China began as early as the Ming Dynasty. Fishermen using “fluorescent” fishing is an example.
