论文摘要
地球上板块构造的存在直接取决于内部粘度对比度，地球的质量，液态水的可用性和内部热源。但是，对于板块构造的成立，旋转速度和革命性周期性的初始条件也必须很重要。地球的初始轨道条件受到核心隔离和月球形成的直径过程的显着影响，这可能导致了板块构造的起始和持久性的最终性。轨道条件的变化可能会使地球以接近线性的趋势发展，以便地球的旋转周期（TP）可以接近地球在其围绕太阳（T1degree）中行驶一个度（TP〜T1Degree）所花费的时间。对于旋转和革命性周期性的这种最佳条件对于地球上板块构造的发展至关重要。该假设对板岩外行星和潜在可居住的太阳行星（例如欧罗巴和火星）的可能性有直接的影响。
The existence of plate tectonics on the Earth is directly dependent on the internal viscosity contrast, mass of the planet, availability of liquid water and an internal heat source. However, the initial conditions of rotational velocity and revolutionary periodicity of the Earth around the Sun too must have been significant for the inception of plate tectonics. The initial orbital conditions of the Earth were significantly influenced by the diametrical processes of core segregation and Moon formation and that had probably led to the eventuality of initiation and persistence of plate tectonics. The change in the orbital conditions could have rendered the Earth to evolve in a near-linear trend so that the rotational periodicity of the planet (TP) could approach the time taken for the planet to travel one degree in its orbit around the Sun (T1degree), that is TP ~ T1degree. Such an optimal condition for the rotational and revolutionary periodicities could be essential for the development of plate tectonics on the Earth. This hypothesis has direct implications on the possibility of plate tectonics and life in extrasolar planets and potentially habitable solar planetary bodies such as Europa and Mars.
