本文提出了一种新的解释稀水醇溶液中离子弛豫反常现象的方法。这一现象被认为是与系统中近似于伪旋节线的lusrerization事件的性质有关|不稳定线的系统只包含基本lusters。提出了赝旋节线将具有不同光泽结构的溶液状态分开的观点。估计了伪旋节的位置。描述了分子光散射的积分强度行为。为了具体说明这些细节，我们对水-甘油溶液中的分子光散射进行了实验研究。考虑了该溶液的平衡态和亚稳态的性质。
A new approa h for the explanation of the anomalous in rease of the on entration u tuations in dilute water{al ohol solutions is developed. This phenomenon is assumed to be onne ted with the pe uliarities of lusrerization e e ts in a system approa hing the pseudospinodal | the instability line for a system ontaining only the elementary lusters. It was proposed that the pseudospinodal separates the states of solution with di erent luster stru ture. The pseudospinodal position is estimated. The behaviour of integral intensity of the mole ular light s attering is des ribed. To spe ify the ne details, experimental investigation of the mole ular light s attering in water{gly erol solution was performed. The pe uliarities of equilibrium and metastable rystallizations in this solution are onsidered.
