Using e^(+)e^(−)annihilation data co.responding to an integrated luminosity.of 2.93 fb^(−1)taken at the center-of-mass energy.s=3.773 GeV with the bEsIII detector,a joint amplitude analy.is is performed on the decay. D^(0)→π^(+)π^(−)π^(+)π^(−)and D^(0)→π^(+)π^(−)π^(0)π^(0)(non-η).The fit fractions of individual co.ponents are obtained,and large interferences among the dominant co.ponents of the decay. D^(0)→a_(1)(1260)π,D^(0)→π(1300)π,D^(0)→ρ(770)ρ(770),and D^(0)→2(ππ)_(s)are observed in both *** the obtained amplitude model,the Cp-even fractions of D^(0)→π^(+)π^(−)π^(+)π^(−)and D^(0)→π^(+)π^(−)π^(0)π^(0)(non-η)are determined to be(75.2±1.1_(stat).±1.5_(sy.t.))%and(68.9±1.5_(stat).±2.4_(sy.t.))%,*** branching fractions of D^(0)→π^(+)π^(−)π^(+)π^(−)and D^(0)→π^(+)π^(−)π^(0)π^(0)(non-η)are measured to be(0.688±0.010_(stat.)±0.010_(sy.t.))%and(0.951±0.025_(stat.)±0.021_(sy.t.))%,*** amplitude analy.is provides an important model for the binning strategy.in measuring the strong phase parameters of D^(0)→4πwhen used to determine the Ckm angleγ(ϕ_(3))via the b^(−)→Dk^(−)decay.

To investigate the nature of the Ψ（3770） resonance and to measure the cross section for e^＋e^-→DD, a cross-section scan data sample, distributed among 41 center-of-mass energy.points from 3.73 to 3.89 GeV, was taken with the bEsIII detector operated at the bEpCII co.lider in the y.ar 2010. by.analy.ing the large angle bhabha scattering events, we measure the integrated luminosity.of the data sample at each center-of-mass energy.point. The total integrated luminosity.of the data sample is 76.16±0.04±0.61 pb^-1, where the first uncertainty.is statistical and the seco.d sy.tematic.
