摘　　要：MATLAB可用于地震地下流体数据求均值、去趋势性变化、频谱分析、自定义函数拟合、井孔水温梯度曲线绘制等操作。基于以上应用,本文进行井水位潮汐因子与气压因子计算,并讨论井水位中潮汐与气压成分的剔除问题。Based on the basic contents of finding the mean value, eliminating the trend change, spectrum analysis, self-defined function fitting, and drawing the groundwater temperature gradient curve from seismic underground fluid using the MATLAB software, we calculate the tidal factor and barometric factor of groundwater level, and discuss the elimination of tide and pressure components of groundwater level.

关 键 词：井水位 潮汐效应 气压效应 重力潮汐理论值 MATLAB
