This paper discusses the influence of quantization errors of quantized discrete stationary rardom data on statistical characteristics, called the quantization errors of statistical characteristics by the author. Expressions of quantization errors are given. From the view-point of decreasing quantization errors, the quantization coefficient q and the sampling interval h must be taken as small as possible.

本文讨论离散平稳随机数据序列量化后所引起的量化误差对数据统计特性的影响,即作者所称的统计特性的量化误差。给出了量化误差的表达式。本文指出,从减小随机数椐统计特性的量化误差角度考虑,应尽可能地减小量化系数q和采样间隔h。

This paper presented systematically a method for statistic inspection andmathematical treatment of experimental data. This method is of significance inpractical use for improving the accuracy of measurement results and increasing thereliability of the conclusion derived from experimental results.

A statistical regressive mathematical model for processing the measured data of lossless network is presented.It has been used to process the measured data in the case of small,middle,and large reflec- tions with the help of a computer.The results show that the model is correct.This model provides a precise and fast method for measuring the tangent networks parameters.The effective extent of tangent network approximate expression in the case small reflection has been analyzed and compared with the method proposed in this paper.It is found that the model has included the effective extent of the approximate expres- sion,and can be applied to calculate the tangent network parameters for any reflection.

提出了处理无耗正切关系网络测量数据的统计回归数学模型。在计算机辅助分析下,用此模型处理大、中、小反射情况下的测量数据。结果表明,此数学模型是正确的。这个模型为测量线法正切关系网络的测量技术提供了精密快速的处理方法,还对已有的小反射情况下的正切关系网络近似式的适用范围进行了分析,并与本文提出的方法进行比较。结果表明,本文的数学模型包含了近似法的适用范围,可以适用于任意反射情况下无耗正切关系网络参数的计算。
