摘　　要：Efficient evaluations of the overlaps and the matrix elements of the Hamiltonian between HFB states are basic blocks to establish post-HFB calculations.Since 2009,Pfaffian has been applied to express the overlaps between two arbitrary HFB states to avoid the combinatorial explosion and the sign ambiguity.
