中文摘要:
      研究了一类带时滞的随机捕食—被捕食系统.在一些简单假设下,建立了两种群几乎时间均值稳定和局部灭绝的充分条件,并得到了其临界值.举出例子,借用MATLAB仿真说明主要结果.
英文摘要:
      A delay prey-predator system with random perturbations is proposed and studied.Under a simple assumption,almost sufficient conditions for stability in time average and extinction of each population are established.The critical value between stability in time average and extinction is obtained.Finally,numerical simulations are introduced to support the main results by Matlab.
