The effective excitation temperature T^{ex} for each of particles was proposed to express the distribution of particles in excited states. Furthermore, the relation equations for chemical equilibrium in two-temperature plasma were developed on the basis of the second law of thermodynamics. At fixed T_g in the range of 6000-9000 K, the increasing T_e from 9000-20000 K encourages the dissociation and ionization of particles, causing the composition of SF_6 plasma at 0.1 MPa to differ markedly from the composition under the condition of thermal equilibrium.}, pages = {991--995}, title = {Particle Composition of High-Pressure SF_6 Plasma with Electron Temperature Greater than Gas Temperature}, volume = {25}, year = {1997} }
