The influence of non linear coefficient on network performance is studied by emulational test. The scope of suitable value and its law are summarized through research, and the practicability in actual projects of BP network is improved. The practice in geo engineering has proved that the constringency speed and precision of network will be improved observably when the non linear coefficient is fixed on by the law in this paper.
