摘要
利用回归分析求解乌鲁木齐台同一钻孔内应变和水位的相关斜率，并用筛选法方差判定其异常，研究相关斜率和地震的关系。结果表明： ①４ 个元件同时出现相关斜率异常时有震率高；②相关斜率正异常映震效果好；③相关斜率属短临异常范畴；④相关斜率异常映震能力具有地区差异性。
The correlation slope of strain and water level in same borehole at the Urumqi station is computed by the regression analysis and the anomaly of slope is identified by the sieve variance method. The relation of correlation slope to the earthquake is researched. The results show that:(1)When correlation slopes of 4 organs simultaneously indicate anomalies then the probability of earthquake is high;(2)If the anomaly of correlation slope is positive, the effect of imaging earthquake is better;(3)correlation slope anomaly is attributed to the short-term and impending ones;(4)The ability of imaging earthquake of correlation slope has the difference of region.
