MgSiO 3 perovskite 的融化的曲线用分子的动力学方法在更低的披风条件下面与有效的对潜力结合被模仿。为 MgSiO 3 perovskite 模仿的州的方程在精确地在大量压力上复制试验性的数据是很成功的,这被显示出。MgSiO 3 perovskite 的模仿的融化的温度的压力依赖与最近的试验性的数据一致。为 MgSiO 3 模仿的融化的曲线首先在在 60 GPa 下面的压力是很陡峭的,然后,它与增加压力变得光滑。在核心披风边界迫使 135 GPa, MgSiO 3 perovskite 融化在 6500 K,它是比从 Zerr 和 Boehler 的试验性的数据的推测的显著地低的。
The melting curve of MgSiO3 perovskite was simulated using molecular dynamics method combining with the effective pair potentials under the lower mantle conditions. It was shown that the state equation simulated for MgSiO3 perovskite is very successful in reproducing accurately the experimental data over a wide range of pressure. The pressure dependence of the simulated melting temperature of MgSiO3 perovskite is in agreement with the recent experimental data. The melting curve simulated for MgSiO3 is very steep at pressures below 60 GPa first, then it becomes smooth with increasing pressure. At the core mantle boundary pressure 135 GPa, MgSiO3 perovskite melts at 6500 K, which is significantly lower than that of the extrapolations of the experimental data from Zerr and Boehler.
