一、概论红外线也是一种电磁波,它位于可见光和微波之间,与其它类型的电磁波相比,仅是波长不同而已.红外线的波长范围是0.76～1000微米,一般把0.76～4微米的红外线叫做近红外,把4微米以上的红外线叫做远红外.近年来,红外线已被应用于各个行业,如军事、金属热处理、各种加热工艺、食品工业、制酒、医疗以及农业等.据国外资料介绍,仅加热一项,其耗能就占工业化国家燃料开
I. INTRODUCTION Infrared is also an electromagnetic wave, which is located between visible light and microwave, which is different from other types of electromagnetic waves only in the wavelength range of 0.76 to 1000 microns, generally 0.76 to 4 microns infrared Near infrared, the infrared above 4 microns called far infrared.In recent years, infrared has been used in various industries, such as military, metal heat treatment, a variety of heating technology, food industry, wine, medical and agriculture, etc. According to foreign information , Heating only one, its energy consumption accounted for the fuel in industrialized countries
