| 摘 要： | 本文从区域补偿模式和实验均衡理论出发,利用重力和地形资料计算了冲绳海槽的均衡响应函数.结果表明,冲绳海槽南段弹性板有效厚度和补偿深度明显大于中段.结合其他地质地球物理资料解释认为,产生这种差异的原因主要是南、中两段岩石圈温度和补偿机制的不同所致.

| Abstract: | Based on regional compensation model and experimental isostasy,the isostatic response function of the Okinawa Trough was calculated by using gravity and topographic data.The results are shown as follows: the effective elastic thickness of the plate and compensation depth in the southern Ukinawa Trough is obviously greater than those in the middle Okinawa Trough.In reference with other geological and geophysical data,the deferences between the two portions are explained to be caused mainly by their differences in temperature of the lithosphere and the compensation mechanism. |

| Keywords: | The Okinawa Trough compensation model isostatic response function and topographic load loads from below |
