A定则B公式是混凝土技术的基础理论之一,深入研讨此问题很有意义。历史是现实的源头,回顾历史才能更好地学习、理解A定则B公式真实含义。强度等许多检测数据是-种不确定性数据,是随机变量。区分数据的性质是学习、理解此问题的出发点。混凝土技术有长达5000余年历史,人们对其认识是漫长的、缓慢的,渐进的,费氏的普适公式与A定则—B公式的出现,正是人们长期实践的各阶段认识上的总结并与相关科技发展密切相关,特别是数理统计的知识是研讨此问题的基础。费雷特的普适公式是首开数理统计在混凝土技术研究中应用的先河。达夫·阿勃莱姆斯的A定则,使人们对混凝土强度规律有了真正理性认识。
A formula B formula is one of the basic theory of concrete technology, in-depth study of this issue makes sense. History is the source of reality. Only by reviewing history can we learn better and understand the true meaning of formula A, Intensity and many other test data is - kind of uncertainty data, is a random variable. The nature of the data is the starting point for learning and understanding this issue. Concrete technology has a history of more than 5000 years, and people’s understanding of it is long, slow, gradual, and Fei’s universal formula and A rule-B formula appear precisely in the understanding of all stages of people’s long-term practice Summarized and related to the development of science and technology are closely related, especially the knowledge of mathematical statistics is the basis for discussing this issue. Feret’s universal formula is the first application of mathematical statistics in the study of concrete technology. Duff Abrams’s A rule, so that people have a real rational understanding of the law of concrete strength.
