Imitative experimental appliance be the resistivity such as simple analog ground electricity situation or single ground electricity unfavorable geologic body, this with practically
Lower complex situations are not inconsistent；And device arrangement form is relatively simple, is only able to achieve the arrangement of solely ball physical detecting device, nothing
Method is detected and is compared using other physical prospecting means, and the repeatability of test is poor.Therefore, developing one can be used for geophysics
The physical analog test apparatus of exploration, to geophysical exploration technology improve and assure the safety for life and property of the people have reuse make
With with great social value and scientific value.
