摘要
To date,some confusion exists in the literature concerning the employment of the diffusion driving force and the calculation of the diffusion velocity for the gas species in a two-temperature(2-T)plasma.In this letter,a derivation is presented concerning the species diffusion driving force and diffusion velocity under 2-T plasma conditions.Expressions for the ambipolar diffusion coefficients and the electric conductivity of the 2-T plasma are also given.
