当前,全面质量管理正在我国金属制品企业中越来越被重视和采用,无论是生产工序中的控制、还是在产品检验,产品创优等活动中,无不采用数理统计的科学方法。它对于提高产品质量、提高我们的素质无需质疑的起了重要作用。对于产品的出厂检验,至今还沿用着国外四十年代曾采用的百分比抽样,我国制品企业的产品从五十年代初就沿用着从苏联传入的这种百分比抽样方法。 At present, total quality management is being increasingly emphasized and adopted in China’s metal products enterprises. Whether it is the control of production processes, product inspection, or product excellence, scientific methods for mathematical statistics are used. It plays an important role in improving product quality and improving our quality without questioning. For the factory inspection of products, the percentage sampling used abroad in the 1940s is still used. The products of China’s product companies have used this percentage sampling method introduced from the Soviet Union since the early 1950s.
