本篇論文主要是研究具時滯參數的非選擇性捕食漁獲系統之整體穩定性。首先，我們先介紹這個模型;而後推導出系統的正均衡點之局部穩定性和整體穩定性的充分條件;最後，我們舉例說明上述結果。 In this thesis, we are interested in studying the stability of the unique positive equilibrium point of a nonselective harvesting of a predator-prey fishery system with time delay. Firstly, we state the formulation of the model. Secondly, we drive different conditions for local and global stability of the positive equilibrium of the system, respectively. Finally, we illustrate our results by some examples.
