摘　　要：转换函数零线等值图在2003年新疆伽师-巴楚ML7.0地震前密集交汇,震后开始发散,进一步证实了地磁转换函数方法对预测地震的有效性。同时,为适应全国地磁台站的记录数据由模拟向数字化的转变,对模拟数据和数字化数据从时间序列和转换函数计算结果两方面进行了对比,为下一步使用数字化数据计算转换函数进行地震预测研究打下了基础。The contour （Value=0） is one of the key factors for predicting earthquake by using the transfer function based on geomagnetic data. This paper show how the contour （Value=0） developed both before the earthquake and after the earthquake which occurred in Xinjiang Autonomous Region in 2003. As a result, he transfer function is proved to be effective for earthquake prediction. At the same time, the transfer function is computed using digital data and simulated data, respectively. It is fundamental for scientists to compute the transfer function using digital data in the future.
