基于微观IBM理论，提出转动诱导出玻色子量子相变的一种可能途径：一旦原子核在受到高能激发或作快速旋转时，假如外界提供的能量足以使玻色子完成拆对顺排，则核处于集体相与单粒子态的共存相，其特征是出现较密集的能谱；假如能量不足以完成拆对或顺排，可能发生两种情况之一，当核旋转达到某个临界转动频率ω c时，或者一个高角动量的玻色子脱离"集体"而"游离"出来，或者发生一个高角动量的玻色子转变为一个低角动量的玻色子，核仍旧处于集体相；均会伴随出现光辐射，产生基态带的一条能级——相变信号。

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。
