分别利用差分方法和有限元方法对一类含有迁移的赤眼蜂 — 螟虫生态系统进行数值模拟，导出了差分方程计算格式和 Ｌ∞ 模误差估计，并利用极值原理证明了数值解的非负性；建立了一种可行的有限元计算格式，并在此基础上导出了最优阶的 Ｌ２ 模和 Ｈ１ 模误差估计
The differential equation method and the finite element method are respectively used to simulate a kind of Trichogramma-Sipopus migratory ecosystem. The difference equation calculation method and the L∞model error estimate are derived. The extremum principle is used to prove the non-negative A feasible finite element calculation format is established, and based on this, the L2 order error and H1 mode error estimate of the optimal order are derived
