摘　　要：Let W be a classical Weyl group and ∏ be the corresponding system of simple roots. For w∈ W, let R(w)={α∈∏|l(ws_α)【l(w)}, where we denote by s_α the simple reflection in the hyperplane orthogonal to α for α∈∏ and by l(w)the minimal length of an expression of w as a product of simple reflections. To any Weyl group one can associate a
