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。
According to the change of water absorption rate of Calligonum rubicundum and C. Caputmedusae over time, four univariate regression models were fitted to determine the water absorption The optimal curve model for the rate is the strict Sumac curve, and the optimal curve model for the fruit of the Curcuma nodosus is modified exponential curve. At the same time, the jujube jujube fruit water absorption of each period and turning point were analyzed.
