Abstract：
Using the Hamiltonian and the natural operators, we obtain a nonlinear spectrum-generating algebra for the symmetrical Pöschl-Teller Potential. This algebra gives a new method with obvious physical meaning to describe and solve the quantum motion in the Potential, and can be regarded as a new deformation of the oscillator algebra.
