摘　　要：对二水平的正交饱和设计统计分析中的max Ur方法进行了更深入的分析,指出了其优点与缺点。然后引入t_统计量对max Ur方法存在的一些问题进行了改进。通过举例模拟结果验证了改进的重要性。The max Ur method in the statistic analysis of two--level orthogonal saturated designs was reviewed and its merits and defects were summarized. Then, the defects in max Ur method were improved by introducing t-statistic. The importance of t_statistic improvement was veri- fied by exampl simulations.
