摘要
根据红皮沙拐枣 (Calligonum rubicundum )和头状沙拐枣 (C.Caputmedusae)吸水率随时间的变化值 ,用 4种单因变量回归模型进行拟合 ,分别确定红皮沙拐枣果实吸水率的最优曲线模型为严格苏玛克曲线 ,头状沙拐枣果实的最优曲线模型为修正指数曲线。同时对沙拐枣果实吸水各时期及转折点进行了分析。
In this paper, the law of water absorbing rate over time is obtained by routine approach from Calligonum rubicundum and C. caput medusae. It suggests that the optimal curve of water absorbing rate of C. rubicundum over time is the Jihson schumacker curve; the optimal singale variable regression model of C. caput medusae is modified exponential curve.
