在本論文中，我們主要想模擬HD76582的碎屑盤，我們以行星和星子(Planetesimal)動態系統來研究碎屑盤的密度分佈。透過調整行星繞行軌道與碎屑盤初始分佈等，觀察不同條件對動態系統的影響，找出最有可能使碎屑盤呈現兩團塊狀態的條件。

In this thesis, we mainly want to simulate the debris disk of HD76582. The planets and grains' dynamical models are employed to study the density distribution of debris disc. We observe the influence of different conditions on dynamic systems by adjusting the planetary orbits and the initial distribution of the debris disk. We try to find the most possible which make the debris disk present two clumps.
