一、引言远红外加热技术是本世纪70年代开始并迅速发展起来的一项既提高产品质量、又节能的新技术。由于远红外热的电磁本性具有较强穿透力，能激发被加热物体内部微观质点产生类似共振的运动，增大内能，因而获得很高的热效应。使政表里同时受热，从而提高热养护的均匀性，提 I. INTRODUCTION Far-infrared heating technology is a new technology that has been rapidly developed since the 1970s and has not only improved product quality, but also saved energy. Because the electromagnetic nature of far-infrared heat has a strong penetrating power, it can stimulate the similar microscopic particles in the heated object to generate resonance-like motion, increase the internal energy, and thus obtain a high thermal effect. In order to increase the uniformity of heat conservation,
