【 摘 要 】

In this paper, we show that the absolute value of the signature ofthe $2$-parallel version of a link is less than or equal to thenullity of it and show that the signature, nullity, and Minkowskiunits of the $2$-parallel version of a certain class of links arealways equal to $0$, $2$, and $1$ respectively.
