The dinitrobenzene with electron-withdrawing group can be hydrogenated much easier than the dinitrobenzene with electron-donating group.
含有吸电子基团的二硝基苯类化合物反应活性明显高于含有供电子基的二硝基化合物的加氢反应；
Thus, I want to appeal everyone join the group of donating organ.
因此，我要呼吁大家参加器官捐献。
Moreover, We found that the relaxation time of H2TPP with donating electron group is about 7 times faster than that with withdrawing electron group.
另外，还发现推电子基团取代的卟啉弛豫过程比吸电子基团取代的卟啉弛豫过程快7倍。
