Abstract
An assertion (see Theorem 1.1) dual to that of Naimark`` is argued. The assertion allows us to regard the unsharp`` quantum mechanics as a result of reducing the usual quantum mechanics by`` means of a kind of projection.`` An algebraical system P_{(H, \pi)} consisting of`` the projections lattice (P(H),\leq) of`` a Hilbert space H and an orthogonal projection \pi `` onto a closed subspace \tilde{H} of H `` is proposed as the mathematical interpretation or model of`` propositional calculus of the unsharp quantum mechanics.`` The mathematical structures surrounding H_{(H,\pi)}) `` are investigated.
