【摘要】通过对乌海 4.6级地震前 CO2 观测值处理 ,并应用“九五”攻关研究新成果中多种数学方法进行异常提取和分析 ,得到了滤波、比值、单点速率等分析计算结果 ,有效地在震前 1个月提取到地震短临前兆异常 ,说明 CO2 这种新方法能在地震短临预报中发挥较好的作用。更多还原

【Abstract】 through processing the data of CO 2 before Wuhai M 4.6 earthquake and using the new methods obtained in"Ninth five years project",we got some results,such as filtering,ratio,single point rate etc..Some imminent anomalies were picked up effectively one month before the earthquake.It shows the method of CO 2 can be very useful in imminent prediction.更多还原
