Study on topographic compensation model of the Okinawa Trough Ⅰ. Calculation of theoretical isostatic response function

本文从区域补偿和实验均衡出发，导出了上部负载和下部负载相关时理论均衡响应函数的计算公式，计算了弹性板有效厚度不同以及上部负载和下部负载的比例不同时的理论均衡响应函数曲线，并对曲线形态进行了初步的讨论．

──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 Okinawa 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.
