In this paper,by using the comparison theorems and constructing suitable Lyapunov function, the sufficient conditions are obtained for the permanence and existence of globally asymptotically stable positive periodic solution of the system.

研究了具有反馈控制的n种群非自治周期竞争系统的持续性，利用微分不等式并构造适当的Lyapunov函数得到系统存在惟一、全局吸引的正周期解的充分条

With the help of comparison theorem, sufficient conditions which guarantee permanence of the system are obtained. For the almost periodic case, by constructing a suitable Liapunov function, we obtained that the system has a unique globally asymptotically stable positive almost periodic solution. Finally, we study a multispecies predator-prey system with stage structure and Holling II type functional response.

第二部分考虑具有阶段结构的非自治扩散捕食系统，利用比较定理得到该系统持久生存的充分条件，其后在概周期情形下通过构造合适的Liapunov函数得到了保证该系统存在唯一一个全局渐近稳定的概周期解的条件。

The Battle of Borodino found its most memorable permanence in Tolstoy's imagining of it in War and Peace.

波罗金诺之役能够不朽，永为后人追忆的，不是史实，而是托尔斯泰在《战争与和平》中的想象。

Making use of the comparison theorem, some sufficient conditions are derived for permanence of the system and non-permanence of predators.

运用比较定理，得到了系统持久生存和捕食者灭绝的充分条件。

By using of the comparison theorem and some results, some sufficient and necessary conditions are derived for permanence of the periodic system and non-permanence of predators.

运用比较定理和一些主要结果，得到了系统永久持续生存和捕食者灭绝的充分必要条件。

Further more, we get the necessary and sufficient conditions for the two-dimensional discrete system, where the permanence and extinction of the system are decided and only decided by the relationship of the non-delay coefficients in the system. Further, we for the first time find the equivalent permanence and extinction between the two-dimensional discrete Lotka-Volterra and its corresponding continuous system.

进一步，本得到了此类离散系统二维自治情形下，其持续生存和灭绝分别等价于系统非时滞系数构成的相应不等式；通过比较本文中二维自治Lotka-Volterra竞争系统的连续和离散两种情形的有关结论，首次发现这两类系统具有等价的持续生存和灭绝性质，建立了这两类系统之间的联系。

Many life time parks will be remember by people because of its special building.these building or rise straight from the ground, or open to spread chen, its generous grand view all sighs the people of this world for the view.they since is the symbol of the meeting topic in a life time park, become a life time park again in the meantime would the thing turn of the permanence is memorial.the 埃菲 the 尔 iron pagoda of france are an example of the typical models.in 1889, paris will build up topic tower-埃菲尔 iron pagoda for a life time park.in the days to come, the 埃菲尔 iron pagoda became the permanent symbol of frances then.but"99 half-hardy expositions in world in kunming"s same in our china left a thing to turn for us of the permanence is memorial-kunming a life time 博 park.

许多届世园会因其独特的建筑而被人们记住。这些建筑或拔地而起，或开放铺陈，其恢宏壮观无不令世人叹为观止。它们既是世园会主题的象征，同时又成为世园会物化了的永久纪念。法国的埃菲尔铁塔就是典型的一例。1889年，巴黎为世园会建立了主题塔——埃菲尔铁塔。日后，埃菲尔铁塔便成为了法国的永久象征。而我们的中国"99昆明世界园艺博览会"同样为我们留下了物化的永久纪念——昆明世博园。

Secondly, combining with our previous discussion on permanence and global attractivity, we weaken our sufficient conditions for permanence and extinction of the species further, and get better results by now.

利用函数的上、下平均值，我们得到系统持久和全局吸引的充分条件，从而，推广了Ahmad和Lazer的有关结果。
