开系下的极限环线

B-Z反应较早是用分光光度计观察颜色的周期性变化^1]。Field采用电动势测定E～t或C～t图^2]。最近大量工作证明上述二种方法仍然是很重要的。B-Z反应是属于非平衡态中存在自组织现象的一个实例,三分子模型^3]和低浓度三分子模型^4]至今尚未找到实例,因而Oregonator成了颇为重要的一个实际模型^5]。原则上直接测到相平面上lgBr^-]与lgCe⁴⁺]的变化。给验证理论提供了一种可靠性。

The Line of Limit Cycle in an Open System

In the nonequillibrium statistical mechanics of Prigogine or Haken,they recognize that the concentrations changed in periodic reaction belong to a limit cycle in phase plane,that is,in the open system,the system has a phenomenon of self-organization.In this paper,used x y recorder,we first observed the forms of limit cycle from experiment and discussed it.
