| 摘 要： | 对桃叶表面润湿性能的预测方法进行了研究。应用OWRK法对不同生长期桃叶的近轴面、远轴面的表面自由能及其分量进行了测定。无论近轴叶面还是远轴叶面,随着桃叶生长期的增长,均表现出表面自由能减小,润湿性能变差,极性分量所占比例下降,色散分量所占比例上升等特性。这些变化与前人对于桃叶表皮蜡的蜡质含量、组份含量变化的研究成果相一致。说明用OWRK法测定桃叶表面自由能及其分量所得结果可靠,可以较好地描述桃叶表面的润湿性能和能量特征。

| Abstract: | The method of estimate the wettability of peach leaf surfaces was studied.The surface free energy and its component of the adaxial and abaxial surfaces of peach leaves in different growing periods were determined by OWRK method.The results showed that with the growing of the leaves,the surface free energy and the wettability decreased on both surfaces.The proportion of its polar component also decreased,while the proportion of its dispersion component increased.The result is consistent with the conclusion o... |
