地方性氟中毒流行程度的综合评判数学模型

Mathematical Models Evaluating Comprehensively the Prevalent Degrees of Endemic Fluorosis

给出了二阶综合评判分析地方性氟中毒流行程度的3种数学模型:模型Ⅰ,模型Ⅱ(·,),模型Ⅲ(·,+)。讨论和比较了3种数学模型的区别与使用方法。

Three second-order multifactorial mathematical models evaluating comprehensively the prevalent degrees of endemic fluorosis were generalized which could be formally expressed as model I(∧ ,∨),modein (·,∨)and model m(·,+). The differences and applications were carefully discussed and compared among the 3 mathematical models.
