In this paper, we first analyze the reliability of an adopted empirical formula for $\\beta$-decay half-lives which is a key ingredient for the $r$ process. Then we apply four different mass tables to study the $r$-process nucleosynthesis together with the calculated $\\beta$-decay half-lives, and the existing $\\beta$-decay data from FRDM+QRPA is also considered for comparison.
