不同金属材料在不同热源加热下的热传导研究

摘要

It uses alcohol lamp flame and infrared ray produced by CO2 laser,which wavelength is 10.6μm to heat copper aluminum and iron,using DIS digital information system to measure the actually changing of tem-perature in different condition. According to this experiment we would find that using infrared ray which pro-duced by CO2 laser and wavelength is 10.6μm to heat copper aluminum and iron will appear opposite phenom-enon compared with the normal,we can get the correct explanation from theoretical analyzing.%本文分别采用酒精灯火焰和CO2激光器发射的波长为10.6μm的红外线对铜、铝、铁正入射加热，用DIS信息化系统测量各种情况下的温升情况。通过实验发现采用CO2激光器发射的波长为10.6μm的红外线正入射加热时铝、铁出现反常温升现象，从理论上进行分析得到了正确的解释。
