Methods Focal iscemia was produced in 35 rabbits by transorbital ligation of left middle cerebral artery, compared with a sham-operated group of 5 rabbits.

健康家兔40只，其中35只经左眶入路，行大脑中动脉闭塞术，术后按0.5h、1h、3h、6h、 9h、12h 和 48h时间点分组，每组5只；另外5只仅暴露大脑中动脉，而不灼断，作为对照组。

The Tujia nationality, distributed around the Qingjiang valley in the west of Hubei, is abundant of primitive ecological culture resource, due to its remote and unaccessible natural environment.

在湖北西部清江流域生活的土家族，由于其闭塞和险恶的自然环境，使之保存了丰富的原生态文化资源，其中又以饮食文化最具特色，本文对此作了全面的探讨和清理，并提出加强保护和开发这种独特而又丰厚的文化资源，以维护文化的多样性。

The results suggested that MoO42- could abate pH decrease and Cl- enrichment, and inhibit the auto-catalyzing acidification effect inside the OCC, so retard the development of underscale local corrosion obviously.

结果表明，MoO42-能有效地减缓闭塞区内pH值降低及Cl-浓集、减弱酸化自催化效应、抑制垢下局部腐蚀。

The inhibition mechanism of MoO42- was that MoO42- transformed the hydrate ferrous oxide deposition film from anions selective to cations selective,and the cathodic process of underscale local corrosion was suppressed when it migrated into OCC.Meanwhile, the migrated MoO42- resulted in increasing the impedance of the film on the substrate metal and so inhibited the anodic process of the corrosion reaction inside the OCC.

MoO42-的作用机制在于使水合氧化铁腐蚀膜由阴离子选择性变为阳离子选择性，H+可以从膜下扩散出去，而Cl-难以扩散到膜下富集，抑制了腐蚀反应的阴极过程；同时MoO42-迁入闭塞区后增大了电极表面膜层阻抗，抑制了腐蚀反应的阳极过程。

They said they are still waiting for reply, then is that too unefficient for them to take two months?

怕你们抢占了广告份额，是不是又回到了闭塞的年代呢？

Ottawa is far away from the Head Office; therefore, most members could not participate in activities held by the Head Office; and the news was relatively unenlightening.

Pit corrosion is a main kind of localized corrosion. The process of forming pit corrosion includes three stages-formation of pit source, development of pit cave and forming occluded corrosion cell. Molybdate series inhibitors can be inhibitive, for it can control three stages of pit development. First, there is apparent synergistic effect between molybdate and phosphate, which can suppress formation of pit source. Second, there is apparent passivation of molybdate inhibitor according to electrochemistry analysis, which let oxidation film in unoccluded cave repassivate.

首先，钼酸盐与磷酸盐或硅酸盐复配的缓蚀剂具有较理想的缓蚀性能，并且有明显的协同作用，从而能抑制部分点蚀核的产生；其次，钼酸盐复配缓蚀剂的使用，从电化学的角度分析，具有明显的钝化性能，且钝化区间较宽、维钝电流密度较小，从而能使未封闭的蚀孔或点蚀核附近的氧化膜再钝化，得到有效的修复；最后，对于还有部分蚀孔发展成为闭塞腐蚀电池的情况，钼酸盐、磷酸盐能进入蚀孔内部并且在酸性条件下生成铁钼磷酸盐，从而有效地减缓了点蚀的恶化，抑制了腐蚀的发展。

DSA displayed stricture or obliteration of ICA in hemi or bilateral,some cases incorporated vertebrae basilar artery pathology also,all cases displayed abnormity vasoganglion in some degree.

DSA造影显示一侧或双侧颈内动脉系统的狭窄或闭塞，部分病例尚合并椎-基底动脉病变，所有病例均有不同程度的异常血管网形成。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
