摘要: 将位错的增殖、淹没与相互反应看作化学反应,位错在热激活作用下具有扩散性质。因此,位错系统是一个反应-扩散系统。依据自组织理论,给出了两个位错密度演化动力学方程,当系统发生结构失稳之后,第一个方程变成第二个方程;第一个方程含有对称性破缺,按Higgs机制将发射偶极子。Abstract: We regard the proliferation, the annihilating and the mutual reactions of the dislocations as chemical reactions, dislocations under action of heat activation will have properties of diffusion. Therefore a dislocation system is a reaction-diffusion system. Two equations of evolution dynamics for dislocation density are given based on the self-organization theory, in which the first equation will be transformed to the second equation when the structure imbalance of the system happened. The first equation contains the symmetry-breaking which will launch doublet according to Higgs mechanism.
