N2 - We interpolate a new family of Teichmüller spaces T#X between the universal Teichmüller space T and its little subspace T0. Each T#X is defined by prescribing a subset X of the unit circle as the exceptional set of the vanishing property for T0. The inclusion relation of X induces a natural inclusion of T#X, and an approximation of T by an increasing sequence of T#X is investigated. In this paper, we discuss the fundamental properties of T#X from the viewpoint of the quasiconformal theory of Teichmüller spaces. We also consider the quotient space of T by T#X as an analog of the asymptotic Teichmüller space.
