摘要:
Based on the existing continuous borehole strain observation, the multiquadric function fitting method was used to deal with time series data. The impact of difference kernel function parameters was discussed to obtain a valuable fitting result, from which the physical connotation of the original data and its possible applications were analyzed. Meanwhile, a brief comparison was made between the results of multiquadric function fitting and polynomial fitting.
