英文摘要	In this paper we construct path integral representations of the boundary states in some special backgrounds such as the U(1) gauge field background, the linear dilaton background, and the open string tachyon background. The initial purpose of this paper is to construct a general solution of the boundary conformal field theory with an analytical approach, mainly for the constraint equations (L-n - (L) over tilde (n))\B] = 0 which are difficult to solve, to obtain a solution represented by string modes from the pure algebraic approach. However in the path integral representation it is easy to transform those algebraic equations into differential equations which can be solved. Another purpose of this paper is to try to explore an open question. We do not know how to construct an exact theory of D-branes in the general background. However much recent research shows the boundary state description indeed seizes some fundamental features of D-branes in rather special backgrounds. Since the general background field effects can be easily introduced in the path integral representation, we argue that the path integral representation of the boundary stare should provide an exact description of D-branes in the general backgrounds.
