The Software System About Two-dimension Forward Of Dc Resistivity And Induced Polarization

Dc resistivity is a kind of resistivity method, which usually used to prove distributed circumstance about level or approximately level shaped rock underground. In this method, we extend the distance between electrodes in the same measuring point; we observe the changing circumstance about resistivity from shallow to deep in the vertical direction; we comprehend the geological circumstance which below the measuring point by our analysis about resistivity curve. We use this method widely, we can use it to find groundwater, and we can research and solve problems about engineering geology, and so on.Induced polarization method is a kind of electrical method, which is based on the difference of different ores and rocks to explore the underground instance by observe and research the domino offect of the earth IP. This method is widely used in our country at present and is in good efficiency. It can be used in the mineral prospecting of metal or nonmetal solid; it can be used to find groundwater, oil gas and geothermal field.My paper will introduce my exploitation of the system software, which is about the forward calculation of the dc resistivity and induced polarization method. I emphasize particularly on the development and research of my system. I will provide friendly man-machine interactive environments, and provide convenient and quickly using mode for the geophysical workers. The most important is that the data processing will be more rulable.The development of the system is based on the platform Visual C++, the facture of interface and some code is rely on the Microsoft foundation class, which is very useful. MFC stands for Microsoft foundation class, which is perfect combination about object oriented program and application frame. It also does some assorted encapsulation on traditional application interface, and establishes programmed frame class. So, we just append some codes. The forward calculation about IP or DC sounding and the analysis about some curves and pictures can be done by mature functions.I divide my system in two parts, one is to design and optimize the interface, the other is to compile code and debug programs. I combine the two parts together, that is once I developing parts of interface then I compiling the corresponding codes, and testing them. When accomplish all the codes and interfaces, I do integrated testing about them.
