中医面部色诊测定方法述评

色诊是中医的特色之一。中医学很重视面部望诊，在《内经》中就对面部五色诊有详细的论述。所谓面部五色诊法，就是运用阴阳五行学说，按五脏配五行五色的理论，通过目测面部表现出的青、赤、黄、白、黑不同颜色变化来进行疾病诊断的一种方法。在现代，随着颜色光学理论的发展和测色仪器的更新，众多专家学者将颜色光学理论和现代仪器，如数码相机、色差计、分光光度计等引入到中医诊断现代化研究的领域，使之更为科学及客观化，以规避人为因素造成的面色诊断的误差。面部望诊的现代研究已取得一定成果，丰富了中医面部色诊的内容，但目前其使用的仪器尚不统一，数据不能反映中医色诊的全部信息，具有片面性，因此需进一步研制更加符合中医五色诊原理的科学仪器。

Determination methods for inspection of the complexion in traditional Chinese medicine: a review

Inspection of the complexion is one of the characteristics of traditional Chinese medical diagnosis. Traditional Chinese medicine puts high emphasis on inspection of the complexion and there exists detailed discussion on inspection of facial expression in Neijing. The so-called inspection of facial expression is a method to diagnose diseases according to the theory of five Zang-organs matching five elements and five colors by distinguishing various changes of facial color, such as green, red, yellow, white and black based on yin and yang doctrine and five elements theory. Nowadays, more and more experts have introduced color optical theory and modern devices into the modern research field of traditional Chinese medical diagnosis with the development of color optical theory and the renewal of determining devices, such as digital camera, color differentiation meter and spectrophotometer, to make the research more scientific and objective and avoid the deviations caused by human factors. The modern study of traditional Chinese medicine diagnosis has made fare progress, consequently enriching the contents of its facial color observation and giving a more scientific explanation of it. However, the devices being used now are still disunited; the data may be unilateral and cannot contain the whole information. So the most important task is to invent and use scientific devices conforming better with the theory of five colors observation in traditional Chinese medicine.
