摘　　要：Let H be a separable complex Hilbert space, and T an injective unilateral weighted shift with the weight sequence {w_n} on H. Now we define the inverse weight shift T₁ of T by T₁e_n=w_n^-1e_n+1, （n≥0）where {e_n}_n=0^∞ is an orthonormal basis satisfying the condition: Te_n=w_ne_n+1. In this letter, we give the following results for （BCP）_θ weighted shifts.
