| 中文摘要: |
| 对重力模型参数随时间变化的规律进行了研究，用正弦函数描述了重力模型参数的波动规律，改进了原有重力模型将参数标定为常数的缺陷，并通过数据拟合对实例进行了验证，结果表明该模型预测精度较高。 |
| 英文摘要: |
| This paper studies the law of gravity model parameters changing over time, using a sinusoidal function to describes the volatility of the gravity model parameters, improving the defects of original gravity model in which the parameters are calibrated as a constant, which is validated with instances through data fitting, and the results show that the prediction accuracy of the model is high. |
