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 coul...
