在化学分析方法的研究试验中 ,首先对其最有影响的关键因子进行试验 ,常是取得成功的简捷途径。单因子序贯优选试验法是用尽可能少的试验次数 ,查找到某个单峰因子的最优值。本文同时概述了用序贯方法原理验证最优值 ,其试验次数可以比一般常用的方法减少一半左右。这些试验法也可以在产品的质量和产量等问题的研究试验中应用 ,尤其适用于试验只能是逐个进行的场合。 In the study of chemical analysis methods, the first test of its most influential key factors is often a quick and easy way to success. Single factor sequential optimization test is to use as few as possible the number of tests to find the optimal value of a unimodal factor. This article also outlines the principle of sequential method to verify the optimal value, the number of tests can be reduced by about half of the commonly used methods. These test methods can also be used in research trials on issues such as product quality and yield and are especially suitable for applications where testing can only be done on a case-by-case basis.
