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，结合其它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。
Based on the regional compensation model and the experimental equilibrium theory, the equilibrium response function of the Okinawa Trough is calculated by using the gravity and topography data. The results show that the effective thickness and compensation depth of the elastic plate in the southern Okinawa Trough are obviously larger than those in the middle. Combined with other geophysical data Interpretation that the main reason for this difference is the South and the two lithosphere temperature and compensation mechanism due to the different.
