摘　　要：采用正交试验及其设计表测定了r值,运用方差分析计算得出影响r值测量的主要因素为试样类型(规格),最后对r值的准确测量给出了合理建议。The r value, tests were arranged by orthogonal experimental design, to find out the major influencing factors on the measurement of r value by means of the method of analysis of variance. As regard to all thickness of sheet, the sample style is major factor which will influence the analysis results of r value. Finally, a appropriate suggestion is given to the accurate measurement of r value.
