Abstract: The period of ancient ceramic can be determined by patter recognition. This paper uses the vector composed of chemical elements of an ancient ceramic sample and a new vector consists of the vector and its grey model GM(1,1) parameters to express the ceramics sample. The period of the sample is determined by near neighbor algorithm adopting grey incidence degree as distance. The Jack knife test accuracy achieves 79.55%. Experimental results verify the effectiveness of grey system theory in the study of ancient ceramic.

Key words: period determine of ancient ceramic, grey model GM(1,1), grey relevancy degree, ear neighbor method

摘要： 利用模式识别方法可以推测古陶瓷出产年代。将古陶瓷中各化学成分的含量组成一个向量，并与该向量的灰色模型GM(1, 1)参数构成新向量，用于描述古陶瓷样品。以灰色关联度为距离定义，使用近邻法对古陶瓷样品年代进行预测，其留一法预测精度达79.55%。实验结果验证了灰色理论可以用于古陶瓷断代。
