In this paper, under some mild conditions,
precise large deviations for partial sums of negatively associated
random arrays in multi-risk models are investigated. The obtained
results extend some known ones, and we find out the asymptotic
behavior of precise large deviations is also insensitive to
negatively associated structures in multi-risk models.}
