【摘要】：利用熱電偶測量了3支不同類型激光筆在不同距離處的溫度變化情況,并對報紙、火柴、棉花3種可燃物進行了引燃實驗。結(jié)果表明,在5~160cm距離范圍內(nèi),0.3 W綠光、0.3 W紅光、1.6 W藍光激光筆光束所能達到的最高溫度分別約為30~40、50~70、170~190℃;引燃實驗中,火柴最易被引燃,報紙次之,棉花最難;引燃能力的強弱依次為1.6 W藍光、0.3 W紅光、0.3 W綠光;一定范圍內(nèi)可燃物與激光筆距離越大,則越難被引燃。
[Abstract]:The temperature changes of three different laser pens at different distances were measured by thermocouple, and the ignition experiments of three kinds of combustible materials in newspaper, match and cotton were carried out. The results show that the maximum temperature of 0.3W green light 0.3W red light 1.6W blue light laser pen beam can reach about 30 ~ 40U ~ 50 ~ 70170 ~ 190 鈩，
