In light of the semiclassical statistical theory and method proposed by Thomas-Fermi, this paper conducts a research of the thermodynamic properties of charged particle system restricted by the homogeneous electric and the resonance field. Based on the derivation of the quantum state density of the charged particle system under the condition of high temperature and weak degeneration, the analytic formula of its chemical potential, internal energy and heat capacity is calculated, follow by a detailed analysis of the influence of the two fields on the chemical potential, internal energy and heat capacity. It is finally concluded that the two external fields exert a high temperature and weak degeneration effect on the charged particle system.
