To simplify our problem, a stoichiometric formula is derived for boundary layers with mass injection and chemical reaction.
为了简化有质量引射和化学反应的边界层问题，首先求得了一个普适的计量公式。

It is proposed that the con cen tratious in the chemical reaction system do not change when the stoichiometric equation changes.
本文提出，在化学反应系统中，物质的浓度与反应计量方程式的书写形式无关。

But traditional Friedel-Crafts reaction has its own limitations, such as requirement of a stoichiometric amount of Lewis acid catalysts and large amounts of undesired products.
