阿勃莱姆斯的A定则是在费雷特普适公式基础上的发展和提高,对混凝土强度理论具有里程碑的意义。保罗米的B公式是在A定则基础上的简化,使数理统计对混凝土中的应用进入新阶段。但与A定则没有质的区别,都是对混凝土强度期望值估计值的计算,其结果应该很接近。A定则—B公式成了现代混凝土的基础理论之一,有很强的现实指导意义。
The Abreus’ A-rule, developed and enhanced on the basis of the Ferrett’s general formula, is a milestone in the theory of concrete strength. The B formula of Paul Mi is simplified on the basis of A rule, making the application of mathematical statistics to concrete enter a new stage. However, there is no qualitative difference with A rule, which is the calculation of the expected value of concrete strength. The result should be very close. A rule-B formula has become one of the basic theories of modern concrete, there is a strong practical significance.
