【摘要】 本文采用空间探测获得的金星和水星的质量和半径测定值,通过求解Emden方程分别建立了4个金星和水星的内部结构模型,图1至图3绘出了内部密度和压力分布曲线。计算出无量纲惯性矩C/MR²后,导出了动力学扁率（C-A）/C的可能的取值范围:金星为（1.68～1.83）×10^-5;水星为（5～6）×10^-4（上限值）。更多还原

【Abstract】 With the observed data on masses and radii of Venus and Mercury obtained by means of space explorations, four internal structure models of Venus and Mercury are built respectively by solving Emden eguation. Curves of distribution of the internal densities and Pressures are given in figuresl to 3. According to the calculated dimensionless values of moment of inertia C/MR², the range of the dynamic flattenings is derived, for Venus it is （1.68～1.83）×10^-5, and for Mercury it is （5～6）×10^-4（upper limit）.更多还原
