摘要
目的 研究探讨S型消亡曲线的推广及其在医药卫生学上的应用。方法 推广S型消亡曲线使其初值符合实际意义 ,得其广义形式。结果 经实例验证 ,S型消亡曲线的广义形式符合实际意义、参数意义明显且拟合效果较好。
Objective To study the generalization of the S shaped extinction curve and its application in medical and hygienic science.Methods A generalized form of the S shaped extinction curve was given by generalizing which fitted the modlel to practical significance.Results It could be seen from the example that the generalized form of the S shaped extinction curve and its parameters had the practical significance and the fitted effect was better.Conclusion The generalized form of the S shaped extinction curve has theoretical and applied value in medical and hygienic science.
