Abstract: A piece of temmoku bowl shard‚which imitated by Jingdezhen in Chenghua period of Ming dynasty‚is studied in this work．At the first‚the observations of the specimen are carried out using the OM．The proton induced X－ray emission （PIXE） technique is used to measure the major and trace chemical constitution and concentration of glaze and body．The results are compared with those of other ancient temmokus．It find that the major chemical composition of glaze of Jingdezhen imitation temmoku is similar to those of Jian kiln temmokus‚and the major chemical composition of body is similar to those of Jizhou temmokus．However‚the visual discriminatiors and mathematics discriminations between Jingdezhen imitation temmokus and Jian kiln temmokus are acquired by pattern recognition． 

Keywords: imitation temmoku‚chemical composition analysis‚PIXE technique‚pattern recognition
