Abstract：
By using the nontrivial rephasing invariants Δ_ia of the KM matrix, all the factors which suppress CP violation effects in the standard model with three generations are discussed. They are: Im Δ_ia/γ (KM), the uneveness in magnitudes of two quantities whose weak phases are going to be compared, the effects of strong phases, etc. The arguments are supported by examples.
