我们认为，最近由L.G.莫雷利（Phys. Rev. {\bf 58 E}，R8（1998）），一般属于定向渗流普适类。特别是，这在数字上适用于这些作者研究的具体例子，与他们的主张相反。对于具有时空混沌的实值系统（如耦合映象格子），我们认为同步跃迁一般属于具有非线性增长限制项的Kardar-Parisi-Zhang方程的普适类.
We argue that the synchronization transition of stochastically coupled cellular automata, discovered recently by L.G. Morelli {\it et al.} (Phys. Rev. {\bf 58 E}, R8 (1998)), is generically in the directed percolation universality class. In particular, this holds numerically for the specific example studied by these authors, in contrast to their claim. For real-valued systems with spatiotemporal chaos such as coupled map lattices, we claim that the synchronization transition is generically in the universality class of the Kardar-Parisi-Zhang equation with a nonlinear growth limiting term.
