地球简史
A brief History of the Earth
摘要：
讨论了引力常量$G$增大的可能性及其对地球历史的影响。该模型与地球物理和天文数据是一致的。该模型预测的早期时期的天数与从化石珊瑚中获得的天数一致。该模型预测，地球最初是寒冷的，并在其演变过程中逐渐升温。$G$变化的确切规律还有待于从地球参数随宇宙膨胀的变化中得到。
英文摘要：
The possibility of an increasing gravitational constant $G$ and its implication on the Earth's history are discussed. The model is consistent with geophysical and astronomical data. The number of days in early epochs predicted by the model is in agreement with those obtained from fossil corals. The model predicts that the Earth was initially cold and is gradually heating up during its course of evolution. The exact law for the variation of $G$ is still to be obtained from the variation of the Earth's parameters with cosmic expansion.
