So it can keep invariable bulk phase transition within a wild neutralization range;AB-I and AB-II show the similar phenomenon in bulk phase transition,but not very similar in methanol and ethanol.Perhaps this is because of competition between hydrophile and lyophobic.

AB-I样品分子链上的磺酸基团(-SO3-)完全电离，与树脂网络外部溶液浓度差始终较为恒定，所以能在较宽的中和度范围内(40%～80%)保持较为恒定的相变体积；AB-I和AB-II在电解质溶液中表现出类似的体积相变规律，而在甲醇、乙醇中表现出不尽相同的相变规律，这可能是由于AB-II中存在亲水力和疏水力相互竞争作用的结果。

It proves that tree top leaves suffer from water stress and hydraulic limitation becomes greater with tree height.Water stress influence tree height growth in several aspects:firstly is the influence of exterior water condition,and community average tree height is positive with exterior water condition.Secondly, hydraulic limitation influences individual tree structure and function.Xeromorphic structure,Lower water potential and turgor pressure limit cell division and expansion,which restrict gas exchange and carbon assimilation capability.However,respiration consumption increases with the spread of tree crown.Shortage of nutrient limits carbon investigation on new leave growth and may ultimately limit tree growth.Thus,the main limitation of tree height is water.

水分对树高生长的限制首先是外在的水分状况，群落的总体高度随外界水分状况的变差而变矮；再就是水力限制对单株树木的结构和功能的影响，水势降低、膨压减小使细胞的分裂和扩展受限，旱生型结构加剧水力对气体交换能力的限制、使光合碳同化能力受到限制、而呼吸消耗却随着树木个体的增大而增大，制造营养物质不足、使得营养亏缺、造成投入新枝叶的营养受限，最终限制了树高继续增长。
