We report the results of a CP violation analysis of the decay B{+/-}-->D{pi{+}pi{-}pi;{0}}K{+/-}, where D{pi{+}pi{-}pi{0}} indicates a neutral D meson detected in the final state pi{+}pi{-}pi{0}, excluding K{S}{0}pi{0}. The analysis makes use of 324 x 10{6}e{+}e{-}-->BB[over ] events recorded by the BABAR experiment at the PEP-II e;{+}e;{-} storage ring. Analyzing the pi;{+}pi;{-}pi;{0} Dalitz plot distribution and the B{+/-}-->D{pi{+}pi{-}pi{0}}K{+/-} branching fraction and decay rate asymmetry, we find the following one-standard-deviation constraints on the amplitude ratio and on the weak and strong phases: 0.06<r{B}<0.78, -30 degrees <gamma<76 degrees , -27 degrees <delta<78 degrees . We also measure the magnitudes and phases of the components of the D{0}-->pi{+}pi{-}pi{0} decay amplitude.
我们报告了对衰变(B^{\pm}\to D\pi^{+}\pi^{-}\pi^{0}K^{\pm})进行的CP破坏分析结果，其中(D\pi^{+}\pi^{-}\pi^{0})表示在末态(\pi^{+}\pi^{-}\pi^{0})中探测到的中性D介子，不包括(K_{S}^{0}\pi^{0})。该分析利用了在PEP-II正负电子对撞机上的BABAR实验记录的(324\times10^{6})个(e^{+}e^{-}\to\Upsilon(4S)\to B\overline{B})事例。通过分析(\pi^{+}\pi^{-}\pi^{0})的Dalitz图分布以及(B^{\pm}\to D\pi^{+}\pi^{-}\pi^{0}K^{\pm})的分支比和衰变率不对称性，我们得到了关于振幅比以及弱相位和强相位的如下单标准差约束：(0.06 < r_{B} < 0.78)，(-30^{\circ} < \gamma < 76^{\circ})，(-27^{\circ} < \delta < 78^{\circ})。我们还测量了(D^{0}\to\pi^{+}\pi^{-}\pi^{0})衰变振幅各分量的大小和相位。
