We introduce a two-species symbiosis-driven growth model, in which two species can mutually benefit for their monomer birth and the self-death of each species simultaneously occurs. By means of the generalized rate equation, we investigate the dynamic evolution of the system under the monodisperse initial condition. It is found that the kinetic behaviour of the system depends crucially on the details of the rate keels as well as the initial concentration distributions. The cluster size distribution of either species cannot be scaled in most cases;while in some special cases, they both consistently take the universal scaling form. Moreover, in some cases the system may undergo a gelation transition and the pre-gelation behaviour of the cluster size distributions satisfies the scaling form in the vicinity of the gelation point. On the other hand, the two species always live and die together.

在学校的教育教学活动中,常有学生顶撞教师的情况发生。一旦学生在大庭广众之下态度恶劣,顶撞教师,教师就可能措手不及、处境尴尬,有时也难免情绪和言行失控。对顶撞问题,不同的解决方式体现出教育者的教育观念和个人涵养。笔者在教育工作中体会到,处理学生顶撞有“五宜五忌”。    一、宜客观公正,忌偏袒不公    顶撞事件无论发生在优等生还是后进生身上,教师都要触及问题的是非本质,不要被历史成见等因素所左右。
