针对膛口焰问题提出一个非Ｆｏｕｒｉｅｒ传热模型，并推导出小口径武器膛口轴向温度场的热力学函数解析表达式．最后从非平衡态热力学角度，探讨了膛口轴向温度场的稳定性问题．给出温度场的稳定性判据．这对深入认识膛口现象有一定意义
A non-Fourier heat transfer model is proposed for the muzzle flame and the analytical expression of the thermodynamic function of the axial muzzle temperature of the muzzle is deduced. Finally, from the perspective of non-equilibrium thermodynamics, the stability of the muzzle axial temperature field was discussed. The stability criterion of temperature field is given. This is of some significance for understanding the muzzle phenomenon
