Mandarin:
氧化还原反应 (yǎng huà huán yuán fǎn yìng)

Explanation in English Language (EN):
A redox reaction, short for reduction-oxidation reaction, is a type of chemical reaction that involves the transfer of electrons between two species. One species undergoes oxidation (loss of electrons), while the other undergoes reduction (gain of electrons). Redox reactions are essential in various chemical processes, including polymerization. Some polymerization reactions are initiated or catalyzed by redox systems, which generate free radicals or ions to start the polymerization process.

Explanation in Mandarin (ZH):
氧化还原反应是还原-氧化反应的简称，是一种化学反应，涉及两种物质之间电子的转移。一种物质发生氧化（失去电子），而另一种物质发生还原（获得电子）。氧化还原反应在包括聚合在内的各种化学过程中至关重要。一些聚合反应由氧化还原体系引发或催化，氧化还原体系产生自由基或离子以开始聚合过程。
