In this paper,the experimental results of the low-temperature resistance and the effect of magnetic field ( H =0T,5T,10T) for heavy fermion compounds CeCu \{6- x \}Ni x(x =0.0、0.05、0.1) between 1.8K and 300K are reported. It is shown that the temperature T \{max\} corresponding to maximum resistance decreases with increasing the content of doped Ni, while increases with increasing magnetic field. The mechanism of this phenomenon is analyzed by Kondo scattering and coherent scattering.
