简介：为部分因素的图案的一个基本、实际的问题是最佳的因素赋值的问题。最近，一些新标准WV标准，NB标准和一致性标准例如概括最小的错误，为比较并且选择部分被建议。在这篇论文，我们显示这些标准为对称的部分阶乘图案同意相当好。

简介：当运用一个实验时，试验性的单位的不同类可以导致处理效果的差的评价。因此，在运用实验前选择一个好堵住的图案是合乎需要的。主要，一个单个块变量在文学被使用为简洁对待不同类。在实践，然而，不同类经常来自多堵住变量。最近，称为B2-GMC的一个新标准为二水平的常规图案被建议与多堵住变量。这份报纸在第一次构造一些B2-GMC图案上建议一个系统的理论。实验者们能容易根据构造方法获得B2-GMC图案。B2-GMC图案的职业人员在节4被加亮，并且有小跑尺寸的图案为实际使用在附录B被公布。
