摘　　要：将信息熵应用于误差测量研究，已经成为非常规统计分布、测量不确定度评定、动态测量等研究领域的热点．本文通过实验加工一批典型零件，并应用熵方法对其进行不确定度评定，作为基于熵概念的误差测量研究典型应用实例。分析结果表明，用熵方法评定测控系统的不确定度与现代不确定度评定方法结果十分接近，对于误差理论研究是一个有益的尝试，具有一定的通用性和实用性。Information entropy is used in the study of error measuring, which has become popular for unco nventional statistical distribution, evaluation of uncertainty measuring, and dynamic measuring, etc. In this paper, a batch of parts is processed by experiment. Then the uncertainty is evaluated by entropy method, which shows a typical application example for error measuring research based on entropy concept. The result of analysis shows that the uncertainty evaluation for measurement and control systems by entropy method is nearly to the evaluation result of the method of modern uncertainty. The entropy method is a useful trial for error theory research, which shows universal and practicability
