一、引言在实际生产过程中,决定产品质量特性的每个因素都是不断波动的。因此,在确定生产工艺条件的设计试验时,应该考虑到各个因素的波动性。目前一些国家采用误差因素设计试验法确定试验方案。但是,这种方法一般只适用于具有“经验公式”的“可计算性”参数设 I. INTRODUCTION In the actual production process, every factor that determines the quality characteristics of a product is constantly fluctuating. Therefore, in the design test to determine the conditions of the production process, the volatility of various factors should be taken into account. At present, some countries use error factors to design test methods to determine the test program. However, this method is generally only applicable to “computable” parameter settings with an “empirical formula”.
