多面函数法在钻孔应变时序资料处理中的应用

Method of multi-Kernel function and its application in borehole strain timing data processing

摘要:

基于现有的钻孔应变连续观测资料，将多面函数拟合法应用于时序资料的处理，讨论了核函数选择不同参数对于拟合效果的影响，得到了最优的拟合结果并分析了其反映的原始数据的物理内涵及应用方向，同时与多项式拟合法的拟合结果进行了简要对比。

Abstract:

Based on the existing borehole strain continuous observations，we use the multi-Kernel function to deal with the timing data and discuss the impact of Kernel function on fitting with different parameter selections． We analyze the physical connotation of the original data and its possible applications． Meanwhile，a brief comparison is done between the fitting results of multi- Kernel function method and polynomial fitting method．
