摘要
作者曾用电子表格ＭｕｌｔｉＰｌａｎ或Ｓｙｍｐｈｏｎｙ和程序语言ＴｒｕｅＢＡＳＩＣ补充并改进了正交试验数据处理，使能迅速获得方差分析、因素显著性检验、按因素分水平地以图象直观地对比因素及水平的贡献等统计分析资料。随着计算机软件的飞跃进步，上述过程的实现变得越来越富有内涵、准确、快速而简单。这里利用Ｅｘｃｅｌ新版本４．０～６．Ｏ的珍贵特性，迅速取得以上资料。此外，还用三维柱形图（直方图）显示因素和水平的相对贡献、建立数学模型并求解有关参数、作试验范围内外的预报（数值模拟）、双因素和各种水平时的性能指标变化的三维趋势曲面图，等等。Ｌｏｔｕｓ１－２－３的用法与此相似。给出方法和步骤，并列举了一些实例说明其应用。
Orthogonal Test Design is widely used to optimize the materials research and engineering parameters. Excel and Lotus 1-2-3 spreadsheet softwares (substituting True BASIC and Symphony or Multiplan, formally used) are utilized to make the data processing easy, quick and comprehensive.Square deviations analysis, significances check, contributions numerals and histograms of variables and levels, deviations evaluation... can soon be displayed on screen within one minute. Forecasting is simple. Examples of optimization of additives and their amounts of GPS-Si3N4 and others have been given to illustrate the procedure.
