解釋
專用材料-
Followed this purpose, the paper used the orthogonal design method, combined the materials and the mathematical statistics knowledge, analyzed the range of intensity and anti - frozen as well as action mechanism contrastively under the single factor function and the multi - factors correlation. proposed that when we mixed two or more extra materials into concrete, we cann ’ t purely increase the quantity of the one to enhance some concrete ’ s performances, which guided by the single factor function. on the contrary, we determined the quantity of this kind of extra material must by the conclusion of specific experiment under the multi - factors correlation
圍繞這個目的，論文採用正交設計方法，結合材料學和數理統計學知識，對單因素作用下和多因素交互作用下混凝土強度及抗凍性的變化幅度及作用機理進行了對比分析，提出在混凝土中摻入兩種或兩種以上外摻料時，不能單純以單因素作用下的實驗結果作為指導，用提高某一種外摻料的摻量來改變混凝土的某項性能時，必須以具體試驗得出的結論來判定該種外摻料的用量。
