The fundamental study of food processing tools in Neolithic China -approach from analysis of using marks-

研究结果表明，中国新石器时代的食品加工工具之一--鞍形石是用来粉碎种子的，其加工对象主要是谷物，如小米和橡子，其使用方法至少有两种或两种以上。由此可见，裴李岗文化所使用的材料，以及受同一文化影响的材料，在石材的使用对象和用途上都存在着差异，山东其他地区使用的方言，其差异可能是由于社会文化的差异造成的。

The result of this study have made the fact clear that saddle querns which were one of food processing tools in Neolithic China were used for crushing and powdering seeds.The objects of processing are mainly cereals, such as millets and acorns, and the usage of quern stones were examined at least 2 or more ways.Moreover, it has become clear that there are differences in the objects and the usage of the stones between the materials which were used in the culture of Peiligang, as well as effected by the same culture, and ones which were used in the other Shandong areas; it is assumed that the differences were due to the varieties of the societies and cultures between the regions.
