中文摘要：

在全系统精度理论模型的基础上，对动态测量系统的精度损失规律进行了分析，并依据动态误差分解与溯源的结果，建立了系统非均匀性分析的定量模型，给出各单元精度损失的不均匀性和不合理性；同时，按照系统等寿命设计原则，提出了动态系统均匀损失理论模型，用于指导系统进行均匀设计，使得系统内的各组成部分能在大致相同的时间内同时失效或损坏，发挥生产资料的最大效率．这显然具有显著科学价值和实际经济意义．

英文摘要：

Based on the whole-system accuracy theory, the rule of accuracy loss was analyzed. The formula of inequality analysis were obtained according to the decomposition and tracing results of dynamic errors. Then, a uniform loss theory for dynamic measurement systems was put forward based on a principle of equality life design to make every error source a simultaneous loss for the maximum efficiency.
