在分析化学中,为用最少试验次数来获得最佳实验条件,方开泰提出了均匀设计法.用均匀设计安排的试验所得到的实验结果若用多项式回归方程拟合,在用最优化方法寻找最佳实验条件,不仅试验效率高,而且结果比较可靠.本文对络天菁-S分光光度法测定铅的体系进行均匀设计试验,获得了满意的结果.本法同样适用于其它分析体系.
In analytical chemistry, in order to obtain the best experimental conditions with the minimum number of tests, Fang Kai-tai proposed the uniform design method. The experimental results obtained with the uniform design of the test results using polynomial regression equation fitting, using the optimization method to find the most Good experimental conditions, not only high test efficiency, but also the results are more reliable.In this paper, the uniform design of the lead-cyanine-S spectrophotometry system was designed and the results were satisfactory.The method is also applicable to other analytical systems.
