 note = {Simple polynomial approximations for the internal partition functions and their derivatives up to the second order are obtained for typical species in high-temperature air.The species considered are O2,N2,O,N,NO,O+,N+,NO+,O2+,N2+,Ar,Ar+,and Ar++.All the polynomials include only up to the fourth order in temperature,and they cover from room temperature to 20,000｡・ (or 25,000｡・ for argon).The results are applied to the calculation of equilibrium flow properties behind incident and reflected normal shock waves at Mach numbers from 4 to 31.Saving of computational time is confirmed without loss of accuracy., 資料番号: NALTM0434000, レポート番号: NAL TM-434},
