Meanwhile, the concentration of Pb,Zn and other heavy metals is rather high in the oxidation zone and decreasesdownward to levels that are unbelievably low for Pb-Zn mine tailings. Theseobservations suggest that heavy metals should be re-immobilized by secondaryminerals, rather than primary minerals, in the oxidation zone, and could be leachedout from suboxic environment due to low rate oxidative dissolution which preventsthe precipitation of secondary minerals in significant amount. Thus, cover scenarioswhich establish a suboxic environment beneath the cover layer might not always beeffective in preventing heavy metal release from mine tailings.Sequential extraction studies indicate that, in addition to heavy metal leaching,oxidation of the mine tailings increased the mobility of residual Zn, and Cu, while Pb remains immobile due to the formation of anglesite (PbSO4). Using the seven-step extraction technique developed by Dold (J. Geochem. Explor., 2003, 80: 55-68), galena dissolves in significant amount at step 2 most probably due to the strong complexing of Pb2+ by acetate, while other metal sulfides dissolve at step 6, which suggest that this extraction technique could not be used to evaluate the mobility of lead in natural environment

重金属含量均低于新鲜尾矿，但以硬化层中的含量最高(Pb、Zn含量分别为0.47%和0.93%)，往下大幅度降低，表明尾矿风化过程中形成的次生矿物对Pb、Zn等重金属元素有较强的固定作用，而次氧化带的淋溶作用造成了金属元素的大量流失；(4)与新鲜尾矿相比，硬化层中铅的可迁移性大大降低，硬化层之下尾矿样品中铅的可迁移性也不同程度降低，这是由于硫化物氧化产生的硫酸根与尾矿中的铅反应形成铅矾(PbSO_4)的缘故；(5)氧化作用使尾矿中的zn、Cu等重金属的可迁移性不同程度地增大，其中对锌的可迁移性影响最大，铜的可迁移性与铁比较相似，铅则容易与硫化物氧化形成的SO_4~(2-)反应形成铅矾(PbSO_4)；(6)为了减少尾矿污染和修复矿山环境，人们提出了各种不同的尾矿覆盖方案，本文的研究结果表明，这些方法不一定能够有效地阻滞污染元素的迁移。

作者强调，他们不能证明抗MOG和抗MBP抗体是否具有使髓鞘脱失的能力，或它们是否表示髓鞘受到破坏的现象，作者表示，抗MOG和抗MBP抗体的分析对于临床上出现分离症状的患者而言，是迅速、低廉，和精确的早期临床预测法，可以预测多重硬化症的发展，而这项研究结果对于咨询和推测发生第一次髓鞘脱失之患者是否患有多重硬化症，是相当重要的。

As a result of chemical contains what hard water softeners, so that water to soften the water, flacherie self-aggregation intracelluar intenerated because the loss of water, when huaguang PD developering is water dilution of 1: 4, press ideal calculation, the working fluid anionic surfactant concentration, in its critical micelle concentration.

由于显影洋含有硬火不硬化剂何使火不硬化，火虽不纬不硬化，可火洋的离子含度并未因火的不硬化而减众，当华平PD显影液被火按1：4浓缩后，按理想状况筹算，处事液洋阴离子暗不天活性剂的浓度，在它的临界胶束浓度边。

Surface of plate face was very smooth, unlike rough, pebbly surface of cemented plates, such as U.S.

碳含量被增加到了VC钢的水平以使其容易淬火；加入适量的铜以减少镍的使用量；又加入少量的钼以加强淬火的硬化能力；在无须牺牲VC级别防护性能的情况下，没有采用对浅层装甲使用渗碳（大多数情况下外国的表面硬化处理方式）的工艺。

Since 1962, when Gross and Lapiere discovered the first MMPs-collagenase, man had discovered various of MMPs in succession, where MMP-2 has a strong degradational effect on extracellular matrix, it is secreted bymacrophage, smooth muscle cells and endothelial cells and so on.

自从 1962年 Gross和 Lapiere发现第一种基质金属蛋白酶一胶原酶以来，人类陆续发现了很多种基质金属蛋白酶，其中的MMP—2对细胞外基质具有极强的降解作用，它由巨噬细胞、平滑肌细胞以及内皮细胞等分泌，在动脉粥样硬化斑块中憎多时降解纤维帽及基底膜的胶原等基质成分，是使纤维帽变薄及加速动脉粥样硬化的重要因素之一。

Methods of the invention may include fitting the dental crowns by adjusting or forming them to provide side-specific features, followed by hardening of the hardenable composition.

本发明的方法可以包括通过调整或成形所述牙冠以提供侧面特定外形特征，接着硬化所述可硬化组合物而使所述牙冠合适。

Later on, hydration of fly ash, slag and gypsum produces gel material enwrapping the surface of ettringite, which increases the strength of H50-6s hardened paste on the one hand, and hold back ettringite weathering on the other hand. So ettringite decomposition is effectively controlled so as to avoid strength decrease of the hardened paste.
