Basee on the mixing-length theory of convection, macroscopical stress of the turbulence is used in hydrostatics equation of the stellar structural and evolutionary model. 摘要以恆星結構與演化理論中常用的混合程理論為基礎，將湍流作用表現出來的宏觀應力引入恆星結構與演化模型中的流體靜力學平衡方程。
Using the idea and modeling method of cellular automata, we establish an evolutionary model to simulate the process which many nations annex each other through war. 摘要利用元胞自動機的思想和建模方法，建立了模擬多個國家通過戰爭彼此兼并的演化模型。
