"Catalytic" 的音标为 [kəˈtælɪtɪv],意思是"催化作用的"。
基本翻译为"催化的",表示能够促进或加速化学反应的物质或过程。
速记技巧可以是将 "cat" 发音为 "催化","yal" 发音为 "作用",组合起来就是 "催化作用"。
Catalytic这个词源自拉丁语,意为“催化”或“引发反应”。它的变化形式包括加缀词“catalyst”和“catalytic”,分别表示“催化剂”和“催化作用”。

英文小作文:
Catalysis is a crucial technology in modern society, which has revolutionized the chemical industry and made it possible to produce a wide range of products more efficiently and sustainably. From fuel cells to hydrogen production, catalytic agents have made a significant contribution to the development of clean energy sources and green manufacturing processes.
Moreover, catalysts have also played a crucial role in the field of environmental protection, where they are used to reduce emissions and improve fuel efficiency in vehicles and industrial processes. The new catalytic reactors can effectively reduce emissions and improve fuel efficiency, making them a key component in the fight against climate change.
However, despite its widespread use, there is still much research to be done in the field of catalysis, exploring new materials and developing more efficient catalysts that can further improve the sustainability of chemical processes and reduce environmental impact.
In conclusion, catalysis is an essential technology that has revolutionized the chemical industry and has a significant role to play in the development of clean energy sources and sustainable manufacturing processes.
