摘　　要：依据量子信息学和量子计算基本理论,在研究低剂量γ射线与神经细胞的相互作用规律及物理机理时,将神经细胞骨架微管中的两种蛋白构型视为两能级原子体系,使用密度矩阵描述脑神经系统中信息位的状态,建立并求解系统的动力学方程。结果表明:随密度矩阵非对角元素的减小,系统的量子相干性迅速降低。因此,低剂量γ辐射可以影响受照者的脑神经功能。According to the basic theory of the quantum information and quantum a dynamics equation s established and solved to study the characteristics and physical mechanism of the interaction of low dose I rradiation with the cerebral nervous system, in which the two-state physical system in the cytoskeletal m crotubule s r^egarded as a two-levela tom system, and the states of information bits in the cerebral nervous system are described by a state-density matrix. The :results ^how that the smaller the non-diagonal elements of the state-density matrix are, the quicker the quantumcoherence of the system decreases. Therefore,t can be concluded that lowdose of I rradiation can affect the inunctions of the rradiated nerve cells of brain.
