周秦时期谷物测算法及比重观念——岳麓书院藏秦简《数》的相关研究

The Measuring Method for Grain and the Concept of Specific Gravity for Its Different Kinds During the Zhou-Qin Period

岳麓书院藏秦简《数》里保存了一些与体积重量换算有关的内容,经过初步分析,可以认为:周秦时期人们计量谷物时习惯用体积测算法,并且测出多种谷物的体积重量比值记录在算术书里;当时人们有可能利用水作为体积重量换算中的标准常量,也可能在生活实践中应用了"比重"的观念。

There are some contents related to the conversion between volume and weight in the Qin bamboo slips on calculating kept in Yuelu Academy. After a preliminary analysis on the contents, the authors think that the measuring method of volume was used to measure grain. There were some records on the conversion between volume and weight in the book of calculating. Water was perhaps considered as the standard constant in the conversion between volume and weight, in which the concept of specific gravity was in practice.
