基于色温测量原理的艾灸热辐射光谱特性研究

The Research About Heat Radiation Spectrum Characteristic of Moxibustion Based on Color Temperature Measuring Principle

为了得到传统中医艾灸热辐射光谱特性 ,本文给出了采用光电色度计测量自燃状态下艾条的三刺激值 ,并在计算出色度坐标基础上 ,用内插法得到自燃状态下艾条的色温 ,最后由plank公式计算得到艾条热辐射光谱特性。结果是自燃状态下的艾条的热辐射特性主要是以靠近近红外的远红外为主 ,包含有可见光成分 ,其谱峰大约在 2 7μm左右。

In order to obtain the heat radiation spectrum of moxibustion in traditional Chinese medicine, an indirect measuring method, which is based on color temperature measuring principle, is proposed. The color temperature could be obtained step by step by measuring three stimulate value of moxa which was in a state of self-ignite using a photometer, calculating chroma coordinate, getting color temperature of moxa using an interpolation method respectively. Finally the heat radiation spectrum of moxibustion could be calculated by plank′s formula. The measured results show that power is distributed over the region very closed to near-infrared mainly, and the wavelength corresponding to peak value is about 2.7μm.
