摘要：

The BCS equations are derived by means of the summation of a particular set of diagrams. For any finite value of π/Ω (where π is the number of pairs of particles and Ω is the degeneracy of the system), these diagrams yield the smallest contribution in powers of Ω-1. To this order, there is no fluctuation in the number of particles. © 1979.
