%X 分别采用相关分析、卷积回归和调和分析三种方法，计算了宝坻井、高村井水位对气压响应的滞后时间。对比分析三种方法计算结果的规律性和差异性、以及各方法计算结果差异性的主要影响因素，从而明确三种方法各自的优缺点以及适应性，为今后方法选择提供参考。<br>The effect of barometric pressure on well water levels is well recognized in continuous observations of seismic ground water fluid, especially in deep confined water. The response of the underground water level to barometric pressure is called the water-level-barometric-pressure effect. The main research emphasis on the water-level-barometric-pressure effect has shifted from how to eliminate the influence of barometric pressure on the water level to the calculation and determination of the well-water-level-barometric-pressure coefficient, and then to the exploration of abnormal changes of the water level in response to the barometric pressure prior to earthquakes. However, there has been little research on the response lag changes of the well-water level to barometric pressure. In this paper, we use three methods, including correlation analysis, convolutional regression, and harmonious analysis, to calculate the response lag time of the water level of the Baodi and Gaocun wells to barometric pressure. Then, we compare the regularity and differences in the calculation results of the three methods to clarify the advantages and disadvantages of each. The study results provide a reference for the selection of methods in the future.
