%X To discuss the connection of the amplitude decoherenc e between a two state system and a harmonic o e of a harmonic oscillator in a finite dimensional Hilbert space and these systscillator,the amplitude decoherenc ems with uniform energy spectr there exit some differences between these systems in some respects,their amplituum are investigated.It is found that thought that de decoherence are quite similar due to the unif ormity of energy spectrum.
