自催化反应的临界现象

Critical Phenomena of Autocatalytic Reactions

提出一种自催化反应模式，证明在非平衡系统中存在类一级与类二级相变之间的转变点。它也代表一种连续相变，并类似于Ｌａｎｄａｕ在他的二级相变理论中所预见的“第二类相变（线）的临界点”（Ｌａｎｄａｕ临界点）。同时指出与后者的区别，例如，两者的临界指数有不同的配置。但是，两者的临界指数仍服从相同的标度律。

Proposing a model of autocatalytic reactions,this paper demonstrates the critical point as a joint of second order like transition line and the first order like one existing in nonequilibrium system. The comparision of this point with the “critical point of phase trasition of second kind” predicted by Landau shows a closed resamblance in their behavior, but also some difference between them. The configurations of critical exponents of these two critical points differ from one anther, though both of them satisfy the same scaling laws.
