时～频转换的时间范围和时间步长研究

RESEARCH ON THE TIME SPAN AND STEP-LENGTH OF TIME FREQUENCY TRANSFORMING ALGORITHM

基于均匀导电大地和可极化大地表面 ,电偶源电场的时间谱在无随机干扰和有随机干扰时 ,用不同的时间区段和时间步长进行频谱转换的计算结果 ,作者在研究了时间谱电阻率( TSR)法的数据解释中 ,将时间谱数据转换到频率域 (简称为时～频转换 )时 ,所需要的时间范围和时间步长。

Based on a series of computed results of time frequency transformation using different time span and step length, with or without random noise added, on the surface of the uniform conductive and polarizable earth, the paper deals with the necessity of researching the time span and step length, and summarizes some important results for interpreting the data of time spectral resistivity method.
