The strong acid is the active site for creaking para-diethylbenzene and ethylbenzene and it has little effect on p-isomer selectivity of disproportionation and isomerization.
强酸位是对二乙苯和乙苯裂化的活性中心，而对歧化和异构化反应生成对位异构体的选择性影响不大。
I save the trouble of saying what I mean by that by recording transference in accordance with the system I suggested earlier (p. 40, para. 6).
在此我的意思是依照我之前建议的系统(本书第49页第6节)记录转移关系。
Results There was no FAP-1 expression in normal controls and low positive expression rate in para-cancerous tissue (6.7%), but high positive expression rate (78.3%) was found in HCC (P<0.01).
FAP-1蛋白在正常肝组织中未见表达，癌旁肝硬化组织中的表达率为6.7%，而在恶性肿瘤中的阳性表达率分别为78.3%，与前两者比较差异有统计学意义（P<0.01）。
The expression level of TIMP-2 in lung cancer tissue was lower than that in para-cancer tissue(P<0.001), there was no significant difference between various pathological types of lung cancer(P<0.05);
肺癌组织TIMP-2的表达低于癌周肺组织（P<0.001），在各种不同病理类型肺癌中的表达差异无显著性（P>0.05），并发淋巴结转移的肺癌组织表达较低（P<0.05）。
