2007年高策、徐岩红老师撰文就山西繁峙岩山寺壁画《水碓磨坊图》的机械原理进行了初步探究。但该文对壁画中水磨机械结构的判断值得商榷,归结到一点,他们没有认识到,这部水磨属于立式水轮通过正交齿轮系统驱动下磨盘转动的传统水磨。此外,壁画《水碓磨坊图》反映了水碓与水磨加工粮食的诸多技术细节,不应被忽视。 2007 high policy, Xu Yanhong teacher wrote an article on Shanxi Fanzhi rock temple mural “Shuigu mill map” of the mechanical principles were explored. However, the article is doubtful about the mechanical structure of water mill in murals. To conclude, they did not realize that this water mill belongs to the traditional water mill in which vertical water wheels are driven by the orthogonal gear system to rotate the grinding wheel. In addition, the mural “Minamata Mill” reflects the technical details of the Minamata and water mill processed grains and should not be overlooked.
