• The linear analysis by the six-moment method proposed by Shirazian for calculating the heat flux in a steep temperature gradient plasma is extended to the second order. The heat flux is expressed in terms of a ratio (inverse of Knudsen number) L/λ, L and λ are the scale length of the temperature gradient and the mean free path. In the collisional and small temperature gradient limit, the second order heat flux is q=0.1416 [1-(9/52)(1-R^2_t)][2/(3-R_t)][2/(1+R_t)]^<5/2>q_L, (Shirazian's first order result is 0.1416 [2/(3-R_t)][2/(1+R_t)]^<5/2>q_L), where q_L is the exact result derived by Landshoff for the Lorentzian plasma and R_t=T_c/T_h, where T_h and T_c are the temperatures of hot and cold walls. The discrepancy between q and q_L comes from the lack of number of moments and the assumed form of the electron velocity distribution function. A new trial distribution function including eight moments is proposed which may be more appropriate for the Lorentzian plasma. A criterion for the choice of good trial function is proposed and tested.
