摘要：

We study the freezing of a disordered spin structure upon continuous cooling to absolute zero for a kinetic Ising spin chain with alternating weak and strong bonds. The kinetic equation for the spin pair correlation function is solved analytically in a continuum approximation. The exponent for the asymptotic dependence of the frozen kink density on a characteristic cooling time is found to be z-1, where z is the equilibrium dynamic critical exponent, for a universality class including power-law and exponential cooling, and 1/2 for a logarithmic cooling program which exhibits threshold behavior.
