In the <i>L</i><sup>2</sup>-supercritical case, we obtain the existence and stability of standing waves. Our results are complements to the results of Carles and Il&#8217;yasov&#8217;s artical, where orbital stability of standing waves have been studied for the 2D Schr&#246;dinger equation with combined nonlinearities and harmonic potential. %K Nonlinear Schr& %K #246 %K dinger Equation %K Orbital Stability %K Standing Waves %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=133051
