摘要	Let F=C(x_1,x_2, x_, x_l+1……x_m), where x_1,x_2,x_ell are differential variables, and x_l+1, x_m are shift variables. We show that a hyperexponential function, which is algebraic over F, is of form g(x_1,x_2, x_m) q(x_1,x_2, x_\ell)^{1}{t} \om_{+1}^{x_{+1}} om_m^{x_m}, \ where g \in F, q \in \bC(x_1,x_2, x_\ell), t \in \bZ^+ and \om_{\ell+1}, \cdots, \om_m are roots of unity. Furthermore, we present an algorithm for determining whether a hyperexponential function is algebraic over F.
