third-order reaction

This reform caused a strong reaction in the society, the farmers called "the third land revolution".

这项改革在社会上引起了强烈反响，被农民群众称为第三次土地革命。

The third is to carry out chemical reaction on surface of fibre to form a metal compound lay-er.

其三在纤维表面发生化学反应，形成金属化合物覆盖层。

The solubility of Ca in liquid manganese and the interaction effect of third element were determined in a sealed Mo reaction chamber by vapor pressure method.

用密封容器气液平衡法，测定了Ca在Mn液中的饱和溶解量及第3组元C、Si、Ni、Al、Cr和As对其的影响。

The third law of motion is that action causes a reaction and that these are equal and opposite.

第三运动定律是：作用引起反作用，这些作用大小相等和方向相反。

Based on the data we got, we believed that there should be a third resonant structure of the reaction intermediate hydroxyethyl thiamine pyrophosphate ( HEThDP) besides the reported enamine resonant structure and C2-a-alkenyl carbanion resonant structure, which might be named enol resonant structure.

根据我们得到的数据，我们认为其重要的反应中间体羟乙基硫胺素焦磷酸（HEThDP）除文献报道的烯铵结构和C2α-碳负离子结构之外，还存在第三种共振结构，即烯醇式结构。
