【摘要】 通过类地行星热历史的比较研究，可以更全面地了解它们的热演化过程．火星和月球不具有板块构造，研究它们的热演化过程时，考虑了岩石层逐渐加厚对行星内部对流的影响，同时也考虑了由对流传热转变为传导传热对它们热历史的影响．参量化模型计算结果表明：火星和月球岩石层随温度的逐渐降低目前大约分别增厚到320km和250km左右;并且，火星幔和月幔分别于1．6Ga前和3Ga前停止热对流，这与天文和空间探测资料一致．更多还原

【Abstract】 Comparative study on the terrestrial planets can provide better understanding of the thermal evolution of the planets. Mars and Moon have no plate tectonics, but intact lithosphere. The thickening of lithosphere of Mars and Moon and transihon from convection to conduction have large effect on their thermal history. It is suggested that the Mars’ lithosphere has thickened to about 320Km and the Moon’s lithosphere has thickened to about 250km. By the modeling, mantle convection ceased 1.6Ga and 3Ga for Mars and Moon respechvely in agreement with observahons.更多还原
