摘　　要：介绍了工厂对大尺寸直角尺精度检测与修复常用的在平台上三直角尺两两互检的方法与原理。在确定直角尺误差时,该方法的缺点是需要逻辑推理,较难掌握,功效较低。为此,提出建立一个数学模型,用解数学方程的方法来代替逻辑推理,确定直角尺的误差。This article introduces the common method and principle about the accuracy test and repair of big-size square rulers by checking each other with three square rulers on platform in factories. When determining the errors of square rulers, the shortcomings of the method are the demand of logical reasoning which is hard to master and low working efficiency. Therefore, a mathematical model has been proposed to replace logical reasoning with mathematical equations and to determine the errors of square rulers.
