Abstract: Based on the inverse P-sets [(XF,XF)], the concept and structure of inverse [P(ρ(σ),η(τ))]-sets with ?random translation characteristics?are proposed. The relationship between inverse [P(ρ(σ),η(τ))]-sets and inverse P-sets is discussed, which shows [P(ρ(σ),η(τ))]-sets are the general forming of inverse P-sets, while inverse P-sets are a special case of[P(ρ(σ),η(τ))]-sets. Four operations including intersection, union set, complementary set and difference set are presented. Furthermore the algebra feature about inverse [P(ρ(σ),η(τ))]-sets is given.

Key words: inverse P-set, inverse[P(ρ(σ),η(τ))]-sets, randomness of element transition, algebra feature
