摘　　要：采用自制激光电离飞行时间质谱(LI-TOF-MS)及多元素成像体系,尝试分析了古瓷片中的多种元素。对一块北宋龙泉青瓷瓷片及一块仿古青瓷瓷片样品进行了表面元素分析,所得多元素半定量分析结果表明,这两种瓷片的胎体和釉面中所含元素的种类及含量存在差异;同时对一块明代青花瓷片进行表面多元素成像分析,获得Co,Mn,Fe,Ni,Ba,Ca,Mg,Na,Al,Si,P,K,Cu,Zn和Rb的元素成像图。The elemental analysis of ancient porcelain shards plays an important role in porcelain provenance study and identification of early precious porcelain.In this study,a piece of Longquan celadon shard made in Song Dynasty and a piece of an imitation of ancient celadon shard were collected.A application of the laser ionization time-of-flight mass spectrometry（LI-TOF-MS） in the elements detection of the body and glaze of both porcelain shards was presented.The elemental analysis results of both shards were found to be different.Also,a piece of blue and white porcelain shard of Ming Dynasty was analyzed and elemental images of Co,Mn,Fe,Ni,Ba,Ca,Mg,Na,Al,Si,P,K,Cu,Zn and Rb were subsequently acquired by a surface elemental imaging system which was developed based on the laser ionization time-of-flight mass spectrometry（LI-TOF-MS）.
