Each of them exhibited sensitive reduction responses of nitryls. It was found that the reduction peak of nitryl of the position 4-nitrate group of 2,4-dinitrophenol showed great difference from that of the position 5-nitrate group of 2,5-dinitrophenol. The difference between the two reduction potentials was as large as 180 mV.

在pH=5.0、0.1mol/LNaAc-HAc缓冲体系中，2，4-二硝基苯酚和2，5-二硝基苯酚在碳纳米管修饰电极上出现灵敏的硝基还原峰，其中2，4-二硝基苯酚分子中四位硝基的还原峰和2，5-二硝基苯酚分子中五位硝基的还原峰显示出明显差异，二者峰电位差达180mV。

Aspirin therapy was associated with a 13% reduction in the odds of all-cause mortality, a 26% reduction in the odds of nonfatal MI, and a 25% reduction in the odds of stroke (p =.03 or less).

阿司匹林疗法被认为可以降低13%的所有原因死亡率，26%的非致死性心肌梗死和25%的中风（(p =。03或更低)，处理后的预防心血管事件数字是30

NO_x decreasing ratio of micronized coal reburning comparing withgeneral combustion is not proportionable to NO_x reduction ratio in reduction zone,which depends on both NO_x reduction ratio and NO_x increment in burnout zone.

超细粉再燃与常规燃烧相比NO_x脱除率与再燃区NO_x还原率不成正比，它是由NO_x还原率与燃尽区NO_x新的生成综合决定的。

The results show that catholic reduction of pyrolusite can be conducted, but the reduction rate is low. The effects of temperature to pyrolusite reduction on the cathode are remarkable. The exchange current density increases with the increase of temperature. The presence of irons is favorable to reduce pyrolusite.

结果表明软锰矿粒可以在阴极上还原，但所占比例较少，温度对软锰矿影响量大，软锰矿在石墨阴极还原的交换电流密度随温度的升高而增大，阴极极化的传递系数很小，添加铁离子有利于软锰矿的还原。
