摘要：

The ordering process of the quenched time-dependent Ginzburg-Landau model for the three-component nonconserved order-parameter in the three-dimensional system is numerically investigated. The form factor is found to obey a dynamical scaling law with a characteristic length growing as t1/2. The density of topological defects and the energy density exhibit a power decay that is consistent with the scaling of the form factor. The interaction of the defects is briefly discussed.
