如果气体密度很小，传统的纳维-斯托克斯方程就不够精确。目前的研究包括所谓的第三近似对 D. Burnett 获得的玻尔兹曼-麦克斯韦方程解的影响。这种更准确的计算结果表明，即使在极端条件下，传播速度也仅偏离通常值 2%。
If the density of gas is very small, the conventional Navier‐Stokes equations are not accurate enough. The present investigation includes the effect of the so‐called third approximation to the solution of Boltzmann‐Maxwell equation as obtained by D. Burnett. The results of this more accurate calculation show that, even under extreme conditions, the velocity of propagation deviates from its usual value by only 2 percent.
