摘 要: 如何更有效地描述和掌握动态系统精度变化规律,已成为当前测量技术领域迫切需要解决的问题。对采用误差表征动态测量系统精度的传统方法所存在的问题进行了分析。以全系统动态测量精度理论中的传递链函数为基础,阐述了用不确定度表征的全面考虑动态测量系统各影响精度因素的精度模型的建模理论和方法,并给出了两种典型动态测量系统的精度模型。
关 键 词: 工程测量技术;动态测量精度模型;传递链函数;不确定度

Abstract: How to describe and grasp the changing regularity of dynamic system’s accuracy has become a hot issue in measurement technology area. This paper analyzes the existing problems in traditional modeling theory which adopts error to characterize the accuracy of a dynamic measurement system. It also describes the modeling theory and method of the dynamic measurement accuracy model which is characterized by uncertainty based on the function of transfer chain in general dynamic measuring accuracy theory. The accuracy model of the dynamic measurement system can take all the influences on the measurement system accuracy into account. At last, it gives the accuracy model of two typical measurement systems.
Key words: engineering survey technology; dynamic measurement accuracy model; function of transfer chain; uncertainty
