    • Abstract
  • The article will discuss about the method of using P. Raab and F. Frischknechts expression of the transient decay voltage for a central loop system, abopting the methodology of making program to counl the all-time apparent resistivity ρτ. The apparent resistivity curve have overcomed the disadvantage of distorted at the left of curves, which occurred by used the latetime apparent resistivity formula for any models.
