shift reaction的用法和樣例：
例句
- Experimental results show that the reaction acts up on transannular-surroundings electron transfer reaction mechanisms.
實驗表明，此反應遵循外環外界電子轉移反應機理。 - The hydrogen transfer reactions were exothermic, so a reduced reaction temperature was in favor of the catalytic cracking desulfurization of thiophene.
由於氫轉移反應為放熱反應，因而降低反應溫度有利於噻吩催化裂化脫硫。
