摘要
本文分析了生长模型对S形生长的弹性描述能力，绘制了参数b3从0到10变化时模型形状变化的空间曲面图形，给出了确定模型拐点等特征点的方法，讨论了模型参数具有生物学意义的取值范围和建模时应注意的问题。
The flexibility of Richards growth model to the sigmoid form of the growth is analyzied thoroughly in this paper. The surface of Ricards growth model with the param-eter b3 ranging from 0 to 10 is especially,illustrated,and the approach to establshing the feature points,such as inflection point,is provided. The parameters'ranges of the biologi-cal significance are also discussed.
