摘要We report the results of an experimental study of the exclusive hadronic decays for D-0 --> K(s)(0)pi(+) pi(-) and (KsK+K-)-K-0 and their resonant structures using BES-I detector at the BEPC Collider. Using the data sample of 22.3 pb(-1) collected at the center-of-mass energy roots = 4.03 GeV, we measured the branching fraction for D-0 --> (K) over bar (0) pi(+) pi(-) to be (5.32 +/- 0.53 +/- 0.40)%, the branching fractions for the decays D-0 --> K* - pi(+), D-0 --> and D-0 --> (K) over bar (0) (pi(+) pi(-))(non-resonant) to be (6.05 +/- 0.32 +/- 0.49)%, (1.17 +/- 0.17 +/- 0.13)% and (1.35 +/- 0.22 +/- 0.17)% respectively. We measured the branching fractions Br(D-0 --> f) to be (1.04 +/- 0.24 +/- 0.16)% for f = (K) over bar (0) K+ K-, (1.12 +/- 0.34 +/- 0.15)% for f = (K) over bar (0)phi and (0.27 +/- 0.13 +/- 0.03)% for f = (K) over bar (0) (K+ K-)(non-phi).
