By using the experimental ratios of cross sections between various decay channels, the partial widths of the $\\ds\\to pn \\pi^0\\pi^0$, $\\ds\\to pn \\pi^+\\pi^-$, $\\ds\\to pp \\pi^0\\pi^-$, and $\\ds\\to nn \\pi^+\\pi^0$ channels are also extracted. Further including the estimated partial width for the $\\ds\\to pn $ process, the total width of the $\\ds$ resonance is obtained.
