- Example Sentences:
| 1. | Such model is as follows where xi ( t ) , xm ( t ) denotes the density of the immature and the mature population predator a " at time t respectively ; y ( t ) denotes the density of the prey population y at time t . the mature predator of x can reduce tins death rate ; by hunting and feeding on the prey } "
所示模型如下：其中， x _ m是捕食者的成年种群， x _ i是捕食者的幼年种群，且幼年不能捕食； y是被捕食者； e ~ ( - )是由幼年到成年的转化的概率；是成熟期。 | | 2. | In chapter one , we classify the individuals of predator as belonging to either the immature or the mature and suppose that only mature population feeds on prey and immature population does not feed on prey . it is assumed that the transition rate from immature stage to mature stage depends on the density of immature individuals . we construct a predator - prey system with stage structure
本文第一章，我们将捕食者种群分为未成年与成年两个阶段，并且假使只有成年个体捕食食饵，而未成年个体不捕食食饵；同时假设捕食种群中未成年个体成熟为成年个体的转化率是未成年种群密度的函数；建立了具有阶段结构的捕食者-食饵模型。 | | 3. | The growth of the both species is of logistic naluf . the mature species - y preys on the mature - x . by using the lyapunov function we obtain the - conditions for globally asymptotic stablility of positive equilibria without harvesting . conditions for global asymptotic stablility of four positive equilibria with harvesting and the threhold of hai vi - sting mature population
但从目前已知的文献来看，对于两个种群同时具有年龄阶段结构，且同时对两个种群进行开发的结果较少，本文通过构逅lyapunov函数，得到了当捕获率不为零时上述模型存在一个全局渐近稳定的正平衡点的充分条件，也就是说，在一定条件下，种群兄。 |
