### Abstract

Traditionally, research on the phenomenological theory for neutral kaon system use the effective Hamiltonian theory based on the Wigner-Weisskopf approximation. For describing this system precisely, we use the state evolution matrix without using the Wigner -Weisskopf spproximation and get four complex parameters to describe the CP and CPT voilation properties of nuetral kaon system. Also we have estimated that when the order of experimental resolution reaches to 10^{-14}, we will have to use state evolution matrix to describe the neutral kaon system and can not use the effective Hamiltonian theory.
