摘　　要：文章讨论了矿物元素配合物生物学效价估计方法。简介了一般方法,重点讨论了常用的斜率比法和平行线法,尤其是影响斜率比法估计结果的因素;笔者认为,剂量-反应模型常常是反应-平台模型,包括分段回归模型,抛物线-平台模型和指数-平台模型等,这是估计矿物元素配合物生物学效价的理论基础和方法原理。The method and principle for the estimation of bioavailabilities of mineral element complex- es were discussed in this paper.The methods were discussed briefly, and the slope ratio method and the parallel line method were emphases, the factors of influencing estimation results of the slope ratio method was analised; the author thinks that the dose - response model is often response- plateau mod- els, which included the segmented regression model, the parabola- plateau model, and the exponen- tial-plateau model. It was emphasized that the response-plateau models is the theory foundation and priciples for the estimation of bioavailabilities of mineral elements complexes.
