摘要：

In the framework of recently proposed effective lagrangians for weak nonleptonic meson interactions the amplitudes of the decays K0 --> 3-pi have been calculated with inclusion of isospin-breaking and meson rescattering effects. The imaginary part of the penguin diagram contribution, which determines direct CP violation in nonleptonic kaon decays, has been fixed with the help of the measured ratio epsilon'/epsilon of CP-violation parameters. The modification of the Li-Wolfenstein relation for the direct CP-violation parameter in K0(KBAR0) --> pi+ pi- pi-0 decays is discussed.
