摘要
在之前的研究中作者发现应县木塔的实测尺寸中存在着三级的模数系统。这些模数不仅包含了前人的发现,它们之间也存在着理想的数学关系。但是其中二级平面模数NP和三级模数a不能折算成辽尺的整数尺寸值。这与张十庆在该塔中发现的"整数尺控制"现象相矛盾,同时也会影响到下料和施工等工作——直接影响了前述模数系统的研究结论的合理性。在研究中作者发现日本有一种传统的木工工具曲尺可以很方便地进行以为比例的长度折算,因此推测在应县木塔中也曾有过类似的工具,并对这一工具的基本特征进行了推测。
In the former research we have noticed that there be a modular system in Sakyamuni Pagoda of Fogongsi Temple in China.Although the conclusion is relative ideal,there still remains a problem.Two module in the system may not be converted to some integer or ideal multiple of Liao Chi(the Chinese foot operated in Chinese Liao Dynasty)found by Shiqing Zhang.It not only contradicts with the findings of Shiqing Zhang of the Method of Integer Chi,an architectural design method,in the pagoda,but also be a serious trouble when the pagoda had been constructing.We also have noticed a traditional Japanese carpenter's tool in a Japanese historic document.It is named Kanejaku in Japanese and is a kind of set square named Quchi in Chinese,which may easily convert the lengths with the ratio of.Thus it is speculated that there been a similar tool in the pagoda.The set square of the pagoda should be a right triangle with the ratio of three sides of 5 to 12 to 13;the longest side of the set square should be 0.75 Liao Chi(22.1cm)long,and the shortest side of the ruler should at least have a shortest scale of 0.85cm long.
