研究了用于控制与测试比较的块设计的A型钻头设计。得出了充分的设计的足够条件。定义了S-0类型的设计，并且表征了A-最佳类型S-0设计。还给出了S-0型设计的A效率的下限。使用下限到A效率，显示S-0型设计可产生有效的设计，用于测试与控制比较。
A-optimality of block designs for control versus test comparisons in diallel crosses is investigated. A sufficient condition for designs to be A-optimal is derived. Type S-0 designs are defined and A-optimal type S-0 designs are characterized. A lower bound to the A-efficiency of type S-0 designs is also given. Using the lower bound to A-efficiency, type S-0 designs are shown to yield efficient designs for test versus control comparisons.
