摘　　要：微管是细胞骨架中的重要组成部分和功能组件,其中充满了液体水。大量水分子与电磁场的相互耦合,微管中的非相干的、与热有关的和无序的分子运动,激发大量水分子从基态到激发态并转化为有序的集体电磁相干辐射。水是Kerr介质,自然在水分子系统中存在非线性极化的Kerr效应。本文相干态在其中传播时随着时间的变化可以演化为宏观量子叠加态。Microtubules, one of the primary components and function units in cytoskeleton system, are filled with water. Due to the interactions between the electronic dipole field of water molecules confined within microtubule and the quantized electromagnetic radiation field, the incoherent, thermal and disordered molecular movement excited the water molecules from ground state to excited state and transferred into the collective coherent radiation. Water is a kerr medium which contains non-llnear effect. When propagating in it, the coherent state we concerned in this paper can evolve into quantum superposition states.
