The contributions of tadpole diagrams including /ital t/ and /ital c/ quark intermediate states to the amplitude of /ital K//r arrow/2..pi.. and EPSILON'/EPSILON are analyzed. The result shows that it is quite possible that their contributions are the most important ones. They may give enough ..delta../ital I/=1/2 enhancement for a reasonable quark relative-momentum cutoff value which depends on the /ital K/ wave function. However, the calculated value of /vert bar/EPSILON'/EPSILON/vert bar/ is too large if we suppose all CP violation effects to come from the Kobayashi-Maskawa phase delta. Perhaps one approach to solve this difficulty is to assume that EPSILON comes mainly from superweak CP violation.
