本文介绍正交设计、均匀设计两种试验设计方法的特点与区别。重点讨论正交设计与均匀设计两种设计方法在混凝土配合比设计中的实际应用。解决具体实际问题,必须依靠专业知识的不断积累,正确选取合适的设计方法,保证工作质量并提高工作效率。强调专业技术人员必须加强数学修养的培养与锻炼。 This article introduces the characteristics and differences of two experimental design methods of orthogonal design and uniform design. Focus on the orthogonal design and uniform design of two kinds of design methods in concrete mix design practical application. To solve practical problems, we must rely on the continuous accumulation of professional knowledge, correctly select the appropriate design method to ensure the quality of work and improve work efficiency. Emphasis on professional and technical personnel must strengthen the cultivation of mathematical training and exercise.
