Let $R$ be an associative ring with unity 1 and let $a,b,c\in R$. In this paper, several characterizations for hybrid $(b,c)$-inverses of $a$ are given. Also, the hybrid $(b,c)$-inverse of $a$ is characterized by the group inverse of $ab$, under certain hypothesis. In particular, existence criteria for the the inverse along an element are obtained. Finally, we get the double commutant property and the reverse order law of annihilator $(b,c)$-inverses.（设R是有单位元1的交换环且a,b,c为R中元素. 本报告给出元素a的混合(b,c)-逆几个刻画. 同时, 在一定条件下利用ab的群逆研究了元素a的混合(b,c)-逆。特别地，沿着一个元素的判断准则被给出。最后，研究了零化子(b,c)-逆的双交换性和反序律。）
