酚氧化酶(phenoloxidase，PO)是一种含铜的氧化酶，广泛存在于微生物、动物和植物体内。

They had suppressed the cathodic process of carbon steel electrode. Their inhibition performance was also related with their molecule stereo conformation and electron configuration. Four of bis-(1, 1'-benzotriazoly)-α,β-diamide compounds linked via-CO 〓CO-chain were synthesized and certified by IR and 〓H-NMR. The minimum energy conformations of these compounds were obtained by MM2 forcefield program. The two benzotriazole moiety in BBT1 was more planar than in other compounds. This was beneficial in increasing the inhibition effects of BBT1. In 0.5M H〓SO〓 solution, BBT1 suppressed anodic corrosion reaction. In 3%NaCl solution, BBT1 suppressed both cathodic and anodic corrosion reactions. 1- [ (1'-imidazolly)-methyl] benzotriazole was synthesized by Mannich reaction.

合成了四个通过-CO〓CO-连接的双（1，1'-苯并三唑）-α，ω-二酰胺化合物，采用MM2分子力学程序优化了它们的分子结构，双（1，1'-苯并三唑）-α，ω-二酰胺化合物的缓蚀作用与其分子内两个苯并三唑单元的空间取向有关系，良好的平面性有利于苯并三唑二聚体的吸附和缓蚀作用，苯并三唑二聚体BBT1分子内两个苯并三唑单元近似平行，所以显示出较好的缓蚀效果。0.5M硫酸中BBT1主要抑制铜的阳极溶解的电化学反应；3％NaCl溶液中，BBT1对铜的阳极溶解和氧的阴极还原过程均有抑制作用，相比较而言对阴极过程的抑制作用更大一些。

Teck Cominco also sold 1,800t of QB-R brand non-LME registered SXEW cathodes at a $47/t discount for July shipment and a further 900t for August shipment at a $63/t discount, both basis 1 month pre-payment. A tender for July shipment of 1,500t of "Grace" brand from Mantos de la Luna mine in Tocopilla attracted a discount of $28/t at the beginning of the month, while an additional 800t lot was sold at a $10/t discount late last week.

Teck Cominco公司还以47美元/吨的折价升水出售了1，800吨QB-R牌非LME注册SXEW电解铜（7月份装船），以63美元/吨的折价升水进一步出售了900吨同类电解铜（8月份装船），两批铜的支付方式都是提前一个月支付。7月初，Tocopilla地区Mantos de la Luna矿生产的1，500吨7月份装船的Grace牌电解铜以28美元/吨的折价升水中标，但上周末出售的800吨铜以10美元/吨的折价升水中标。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
