2. acetylene lamp（乙炔燈）：一種用于焊接的工具，其原理是利用乙炔燃燒產生高溫。

3. acetylene torch（乙炔焊炬）：一種用于焊接的工具，通過燃燒乙炔產生高溫進行焊接。

4. polymerization（聚合）：在化學中，炔烴可以通過聚合反應形成高分子化合物。

5. acetylene oxide（乙炔氧化物）：一種有機化合物，可以用于生產聚合物和藥物等。

6. acetylene-based polymer（乙炔基聚合物）：一種由乙炔聚合而成的材料，具有高強度和高耐熱性等特性。

7. acetylene-carbon（乙炔碳）：一種由乙炔形成的碳結構，具有高度可反應性和高度導電性等特性。

8. acetylene reduction（乙炔還原）：化學中一種反應過程，可以將乙炔轉化為其他化合物。

9. acetylene-carbon monoxide reaction（一氧化碳與乙炔的反應）：一種化學反應過程，可以生成多種化合物，包括一些重要的有機化合物。

10. acetylene-butadiene-styrene（ABS）polymer（乙炔丁二烯苯乙烯聚合物）：一種高分子材料，具有優良的物理和機械性能。

以上這些單詞都與炔烴及其相關反應和化合物有關，反映了其在化學和工業中的重要性和廣泛應用。

英文小作文：

Acetylenes are a type of chemical compound that are highly reactive and can exist in a variety of forms, including but not limited to acetylene gas, acetylene flame, and acetylene-butane mixture. Acetylenes have been used in various applications, including welding and cutting, as well as in laboratory settings for igniting materials. Acetylenes are also commonly used in fireworks and other pyrotechnic devices to create bright and colorful displays of light and sound. However, they are also highly flammable and can pose a safety hazard if not handled properly. Therefore, it is important to use proper safety precautions when working with acetylenes to ensure the safety of individuals involved.
