英文关键词：Chinese lacquer ware from Han Dynasty Imitated sample Comprehensive method

中文摘要：通过制备并分析一系列模拟漆膜样品。建立了有助于鉴定汉代漆器成分的剖析方法。经裂解气相色谱、差热分析、色谱一红外联用等现代分析技术对出土的汉代漆器残片样品的综合分析，证实在西汉漆器制造中已使用桐油或其它的添加剂，并依据剖析的结果，对某些汉代漆器的原材料差异作了初步探讨。

英文摘要：Chinese lacquer ware under a long process of development, was commencing perhaps asearly as three millennia ago. By the six century, it was wide1y circulated to overseas withspreading of Buddhism. In Japan, there still have well preserved lacquer wares to be brilliantcolour overthousand years in thc temple. Anyu;ay. several filmous style of lacquer wares wereavailable in China as art obJects or commodities at present. With the characteristics of orien-tal national style such as attractive design. beautiful c0lour etc， Chinese lacquer ware has ex-cellent artistic letIel w'hich carr} ft)rt"ard the good traditions being known from objects of HanDynasty.Fortunately. a series of broken fragments of lacquer ware from Han Dynasty grave wereobtained. It is of interest to detect the composition of fragments, by which the quality of mainingredients used in manufacturing lacquer ware would be known. Therefore, somemodernanalytic techniques are applied towards this goal including PyGC- DTA, andPyGc-IR. Here. we introduce a comprehensive method, which gives the identification to dis-tinguish the differences between samples and also discover the tungoil as an additive in someof them.According to the chromatogram of pyrolysis products. the various samples can be distin-guished by the retention index(r21). In DTA measurements- if the content of tungoil is over50% in the samples. four exothermic peaks would be appeared in the DTA curve. However,the tungoil additive would be detected directly by PyGC-IR measurement without anyreference samples due to investigate the ester group being changed into hydroxyacid duringpyrolysis process.
