配位学说-
运用维尔纳（A.Werner）配位学说和立体化学有关理论，分析研究了无机、有机缓凝外加剂的分子结构和特征，发现缓凝外加剂都是配位化合物，化学本质是配位键。
Werner 's theory of coordination and some related theories of 3D chemistry were employed to study molecular structure and characteristics of inorganic and organic retarding admixtures . It was found that retarding admixtures belonged to the category of coordination compounds , its chemical nature was attributed to coordination bond .
