1 两用仪的频谱治疗机理任何一个物体,在任何温度下都要发射各种波长的电磁波。这是由于物体中的分子、原子受到了热的激发,因而称之为热辐射。热辐射在量值方面和按频率(或波长)分布方面都取决于辐射体的温度。实验表明;不同物体在某一频率范围内发射和吸收电磁辐射的能力是不同的(即选择性发射和选择性吸收)。但是,对某一个物体来说,若它在某频率范围内发射电磁辐射的能力越大,那么,它吸收该频率范围内电磁辐射的能力也越大。人是恒温体,能通过全身的皮肤,不间断地发射出强度较弱的远红外光波(属于电磁波中的一波段),其频谱约在3×10~(11～13)Hz的范围内,波谱约在30～1000μm的范围内。因而,人体能通过皮肤选择性地吸收与自身 A dual-purpose spectrum therapy mechanism Any object, at any temperature to launch electromagnetic waves of various wavelengths. This is due to the molecules in the object, the atoms have been stimulated by heat, so called heat radiation. Thermal radiation depends on the temperature of the radiator both in magnitude and in frequency (or wavelength) distribution. Experiments show that different objects have different abilities to emit and absorb electromagnetic radiation in a certain frequency range (ie, selective emission and selective absorption). However, for an object, the greater its ability to emit electromagnetic radiation in a certain frequency range, the greater its ability to absorb electromagnetic radiation in that frequency range. People are body temperature, through the body’s skin, uninterrupted emission of weak infrared light (which belongs to a band of electromagnetic waves), the spectrum of about 3 × 10 ~ (11 ~ 13) Hz range, The spectrum is in the range of about 30 to 1000 μm. Thus, the body can selectively absorb itself through the skin
