摘　　要：选取库尔勒台十五数字化改造后的气压和水管倾斜观测资料,利用小波分析方法分离观测数据中的信号,将相同频段的水管与气压进行相关性分析。分析结果表明,气压对水管倾斜观测的影响主要表现为线性关系,并且气压对水管影响的优势周期是64~128 h。This paper selects air pressure and water tube tilt observation data of Korla station after digital reconstruction, separates the signal of data based on Wavelet method, analyses the correlation of air pressure and water tube tilt observation data which appears to be the same frequency. The a- nalysis results show that the influence of air pressure on water tube tilt is mainly shown as a linear relationship, and the dominant period of air pressure influence on the water tube is 64 - 128 h.
