Equireplicate Balanced Block Designs with Unequal Block Sizes
本文给出了利用组可除设计构造不等区组大小的等重复平衡区组设计的方法，并列表展示了处理重复次数不超过25次的平衡设计，这些设计的方案可从现有文献中获取。
Methods are given for the construction of equireplicate balanced block designs with unequal block sizes using group divisible designs. Balanced designs in which treatments are replicated 25 times or less are tabulated. The plans of these designs can be readily obtained using existing published sources. Some of the designs given here are even smaller than those in balanced incomplete blocks.
