1·The reactive species, which may be a free-radical, adds to a monomer molecule by opening the p-bond to form a new radical.

这个带有自由基的反应种通过打开双键加入到单体分子上，从而形成新的自由基。

2·Plasma includes many reactive species such as ions, atoms and molecules, and as result it has wide applications in the preparation of diamond films.

3·These reactive species can lead to uncontrolled reactions with polymers and certain metals, liberating heat and causing further dissociation of NF3.

这些活泼的氟会导致无法的控制的同聚合体和特定金属的反应，释放出热量，导致NF 3的进一步分解。

4·It comprises transport of activated gas from a remote plasma source to an area in the chamber in a uniform way through at least two injection points on equivalent paths for the reactive species.

所述方法包括通过至少两个注射点且在用于反应性物质的等同路径上以均匀的方式将被活化的气体从远程等离子体源输送至所述室中的区域。

5·These damages may arise from reactive oxygen species, intercalating agents, radiation, depurination, and deamination.

这些损害可能是由于活性氧，嵌入剂，辐射，脱嘌呤和脱氨作用引起的。

6·With lastingness of infection, the productive rate of reactive oxygen species decreased gradually, and photosynthesis also weakened.
