【Abstract】 The VLF methods was first used for mineral prospecting around 1960, and can be used to find steeply dipping structures that differ from their surroundings with regard to electrical resistance. It is a powerful tool for regional geology investigation, especially in finding local tectonics. The DDS—1 instrument is portable, sensitive, easily-operated geophysical instruments designed according to VLF methods, but these is not a special software to process the data collected in using this instrument which lead to the data processing is laborious, easy-error, time consuming. So it is necessary to develop computer software to quickly, accurately process the data and display the processing results graphically. In this paper, some procedures are implemented to dispose the data from DDS—1 instrument based on the theory of VLF(Very low frequency) and the technology of VBA(Visual basic for application). And they are compiled, stored in Excel. By these procedures and Excel software the processing of the data from this instrument is quiet easy, exact and efficient.更多还原
