引言自从1800年赫胥尔(Harschel)发现红外线起,人们就注意到了红外线的热效应。1935年美国的格罗维尼(Groveny)首先取得将红外线用于加热和干燥的专利权,当时使用的辐射源是最强辐射波长为1μm的红外灯泡。随着红外基础理论和加热机理研究的深入,人们发现许多物质能够更好地吸收长波红外线(即远红外线),于是便不断地研制出新型的远红外辐射源。日本自1968年宣布研制远红外辐射材料成功以来,短短十几年,其远红外加热技术 Introduction Since the discovery of infrared in Harschel in 1800, people have noticed the thermal effects of infrared. In 1935, Groveny, the United States, first obtained the patent of using infrared rays for heating and drying. At that time, the radiation source used was the infrared light bulb with the strongest radiation wavelength of 1μm. With the deepening of the basic theory of infrared and the heating mechanism, many people find that they can absorb the long-wave infrared (far-infrared) better, so they developed a new type of far-infrared radiation source. Since Japan announced the successful development of far-infrared radiation materials in 1968, its far-infrared heating technology
