The results shown that 12-molybdophosphoric acid did play inhibition in radical reactions, and the mechanism was conformed as electron capture theory.

通过使用电子顺磁共振仪对苯乙烯自由基聚合体系中自由基的跟踪测试，进一步证实12-钼磷酸确实能够在自由基聚合体系中起到阻聚剂的作用，而且更加明确地提出其阻聚机理：通过捕获体系中的电子达到抑制自由基聚合反应的发生。

Experimental results indicated that performic acid and hydroxyl radical produced in 30% H2O2-HCOOH-Fe(superscript 2+) were combined to oxidize model organic sulfide with desulfurization ratio of over 96%. Catalytic performance of the combination of Fe(superscript 2+) and formic acid was higher than thin of only formic acid.

实验结果表明：30%H2O2-HCOOH-Fe(上标 2+)产生的过氧甲酸和羟基自由基能迅速将模型有机硫化合物氧化，氧化脱硫率可达到96%以上，Fe(上标 2+)和甲酸的催化氧化性能明显优于单纯使用甲酸。

Results:The results show that the survival rate of mammary epithelial cells were decreasing gradually with the increasing of the time of TGF-β1 treatment, and the survival rates of 24 h and 48 h groups were significantly lower than that of control group (p.05); the LDH activity of 6 h、12 h、24 h and 48 h groups were significantly higher than that of control group (p.05); the DNA degradation arisesed in 12 h, 24 h, and 48 h groups' mammary epithelial cells; the activity of Caspase-3 reach to a peak at 24 h, which was significantly higher than that of control group (p.05); the acinus of epithelial cells appears to break off and collapse with the increasing of treatment time, but the leydig structure keeps integrate;...

结果表明：1、5、10 ng/mL的TGF-β1均能抑制乳腺上皮细胞的增殖，且随浓度增加抑制作用加大，呈现剂量依赖性，其中10 ng/mL TGF-β1组与对照组差异显著（P.05）；10 ng/mL TGF-β1作用于乳腺上皮细胞24 h，随作用时间延长细胞凋亡率逐渐增加，6 h、12 h和24 h组与对照组相比差异极显著（P.01）；LDH活力也不断升高，6 h、12 h和24 h组与对照组差异显著（P.05）；DNA随 TGF-β1作用时间的延长发生不同程度降解；TGF-β1作用2 h~6 h细胞大量表达HSP70，6 h达到高峰，而后下降，2~12 h的表达量均显著高于对照组（P.05）。结论：TGF-β1可以抑制奶牛乳腺上皮细胞的增殖，具有浓度依赖性。10 ng/mLTGF-β1。。。
