Encoding information by firing pattes is one of the basic neural functions, and synchronization is important collective behaviour of a group of coupled neurons. Taking account of two schemes for encoding information (that is, rate coding and temporal coding), rhythm synchronization of coupled neurons is studied. There are two types of rhythm synchronization of neurons: spike and burst synchronizations. Firstly, it is shown that the spike synchronization is equivalent to the phase synchronization for coupled neurons. Secondly, the similarity function of the slow variables of neurons, which have relevant to the bursting process, is proposed to judge the burst synchronization. It is also found that the burst synchronization can be achieved more easily than the spike synchronization, whatever the firing pattes of the neurons are. Hence the temporal encoding scheme, which is closely related to both the spike and burst synchronizations, is more comprehensive than the rate coding scheme in essence.

摘 要：社会动员是有意识、有目的地动员、组织社会成员积极参与重大社会实践以完成重大社会任务的过程。社会动员以思想动员为主线，是动员主体实施动员的过程，是动员对象响应动员的过程，也是动员主体与动员对象双向互动的过程，归根到底是从群众中来到群众中去的过程。透彻分析社会动员过程，对于深入贯彻党的群众路线，充分依靠和动员广大群众投身社会主义现代化建设，具有重要的现实意义。 关键词：社会动员； 思想发动；
