1. These biological phenomena can be described as all kinds of mathematical models by dynamics theory and the
bionomic problems can be controlled through the investigation of these models.
这些生态现象可利用动力学建模方法来建立各种模型，通过对这些模型的研究达到对某些生态问题的控制。
2. Further, limits of cost per unit effort and maximum value of the effort for joint harvesting of these four types of two-species are derived from analyzing the existence of
bionomic equilibrium.
进而，通过分析生态经济均衡的存在性得到了单位努力量使用成本的限制条件和努力量的上确界。
