THE FAST METHOD OF MUTING VALUE OF DATA SECTION

In the measurement of the high density resistivity method,there is often some false data in the data section because of the influence of poor earth contact of electrodes and other interference factors etc.,which can cause false abnormality of data section and make data interpretation difficult.This paper puts forward a kind of fast and effective method of muting value based on the curvature formula,and it can automatically discern mutating data using half two rank difference method and get rid of the false data.In order to make full use of the materials of data section and compensate the losing data,then it was interpolated with the method of one unit three point or trend surface stacking and residual error interpolation,which make it to be convenient for the qualitative or half fixed quantity interpretation.At last,the model and practical data including mutating data are processed with this method and the processing results show that the false points of data section are completely rejected without losing the useful information,and it is easy to be interpreted.So that it is feasible and worthwhile for application.
