Both charge inversion and flow reversal can't be accounted for in continuum theory.

连续性理论无法解释电荷的倒置与反转电渗流这两种现象。

The results show that the emission level of the cyclic flow reversal combustion is lower than that of one-way flow combustion.

结果表明，相对于单向流动，往复流动有更好的燃烧排放效果。

The existence and uniform boundedness of the global solutions of the model for sulphur dioxide oxidation in a tubular reactor with periodic flow reversal are proved by the invariant domain method.

利用不变区域方法，证明了二氧化硫催化氧化管式反应器流向变换强制操作模型整体解的存在性和一致有界性。
