【Abstract】 It is practicable to control and nitrogen potential by electro-resistivity prospecting by means of experiments,The research results show that the resistance value is still a hear function of the carbon and nitrogen potential,Under given conditions,it is expressed that R=26.089+1.27·Gp+1.75.Np ; Using the dilute solid-solution theory,it is testified that the model can indicate really the contributions of carbon and nitrogen atom to R,and the general physical formula is founded,namely:更多还原
