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(shí)驗表明，此反應遵循外環(huán)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.
由于氫轉移反應為放熱反應，因而降低反應溫度有利于噻吩催化裂化脫硫。
