摘　　要：分析了非线性误差的产生机理,详细论述了非线性误差的有效估算方法;依据此方法给出了非线性误差的超差处理手段和流程图。通过编制程序,仿真验证了所述方法的正确性,从而为后置处理中超差处理提供了可靠依据。This paper analyzes the generation mechanism of non-linear error, and it discusses in detail the effective method for estimation of non-linear error. On the basis of method above-mentioned, this paper provides the processing method and the flow chart for over-proof of non -linear error. By programming, it emulates and tests the method stated in this paper, and the result is correct. Accordingly, this paper provides an inerrable basis for the processing method for over-proof in post-processing.
