采用龚珀兹曲线模型预测农机产品市场销售趋势及对饱和容量进行研究,并结合具体数据加以应用。
By building up tumor growth aerodynamic model,when tumor growth aerodynamic laws is research to find: The process of tunor increasing squares with economic growth of Gompertz growth parabola description;we further study that Gompertz growth parabola squares with population growth and regulation of Logistic growth parabola description.
通过建立肿瘤增长动力学模型,研究肿瘤增长动态规律时发现:肿瘤增长的全过程与龚珀兹增长曲线描述的经济增长过程完全相符;进一步给出了龚珀兹增长曲线与描述种群的增长与调节的逻辑斯蒂增长曲线完全相似。
