Reinforced Lattices
研究了在非正交设计的区组中添加标准处理来强化格子设计的方法，适用于正方形和矩形格子，可帮助比较现有处理或与标准对照。
SUMMARY Reinforcement is here meant the addition of plots of standard treatments to the blocks of a non-orthogonal design to improve it. The purpose could be either to aid a comparison of the existing treatments or to facilitate their comparison with the standards. The position is examined for both square and rectangular lattices in block designs and for rectangular lattices in row-and-column designs. It is concluded that the method could be useful in practice.
