两侧都有对称肩的石器通称为双肩石器。本文专为讨论我国新石器时代双肩石器的分布、分类、起源及用途等问题,企望对史前生产工具的研究能有所补益。一、发现黄河流域双肩石器的使用具有最悠久的历史,特别是在中原地区,在新石器时代早期就具有使用双肩石器的传统。迄今发现的最早的裴李岗文化磨制石器中,就包括有相当数量的双肩石铲。这些石铲一类稍长,一类较短,均为圆弧刃。铲叶平薄,双肩上收形成较长 Both sides have a symmetrical shoulder stone known as the double-shoulder stone. This article is devoted to discussing the distribution, classification, origin and use of the rock and stone in the Neolithic Age in China. It is hoped that the study of prehistoric production tools can be of some help. First, it was found that the use of the shoulder stone in the Yellow River Basin has the longest history, especially in the Central Plains, where the use of the double shoulder stone was traditionally used in the Neolithic Age. So far found the earliest Peiligang culture mill stone, including a considerable amount of double shoulder stone shovel. These stone shovels are slightly longer ones and shorter ones, all arc edges. Blade blade flat, shoulders closed to form a long
