英文摘要	Experimental data of the nuclear beta-decay half-lives are systematically analyzed and investigated. We have discovered a new formula for the beta(+)-decay half-lives of nuclei far from the beta-stable line. It is stated that the logarithm of the half-life of beta(+) decay with a same order depends linearly on the neutron number of parent nuclei along any isotopic chain. This shows that there is a new exponential law between the half-life of the beta(+) decay and the nucleon number (Z, N). The possible physics behind this new law is discussed. Experimental data are well reproduced by this simple and accurate formula with four parameters. This new formula can be used to predict the beta(+)-decay half-lives of nuclei far from stability. It is useful for experimental physicists to analyze the data of beta(+) decay.
