At the end of a cycle you have to harvest the material out, you have to reseed the filaments and restore it to where it's ready to receive the reactive gas — and that's a lot of nonproductive time.

在一个周期结束时，您将成品取出时，你必须在已经准备好接受反应气体的地方补种的细丝。

The chemical calorific effect has a great influence on the temperature, the reaction rate, the polymer material structure and rheological property in reactive extrusion processes for polymerization.

在聚合反应挤出过程中，化学热效应显著影响材料体系温度，从而影响反应速率以及高分子材料结构与流变性能。

This matters because the atoms on the surface of a material are generally more reactive than those at its centre.

ECONOMIST: Small wonders

Atoms on the surface of a material are generally more reactive than those inside (which is why powders dissolve more quickly than solids do).
