摘要
介绍了柯斯二氏检验方法的检验原理 ,举例说明了其在点焊质量控制方面的应用过程。与常用的其它统计检验方法相比 ,柯斯二氏检验方法具有功效高、计算简单、不需要人为分组、不受样本容量大小限制等优点 。
This paper introduces the principle of the kolmogorov-smirnov test and illustrates its application in spot welding quality control. In comparison with other statistic test methods, the kolmogorov-smirnov test has many advantages, such as high power, simple calculation, no need for grouping artificially, and no limit of specimen numbers. Therefore, the kolmogorov-smirnov test is a better method which can applied to test of normality for stability of spot weld quality.
