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。

Background: The neuron death resulting from traumatic brain injury can be classified into 3 types:(1)neuron death due to primary injury;(2)neuron necrosis due to secondary injury such as hemorrhage, compression, anoxemia and ischemia;(3)neuron apoptosis due to inflammatory factor, cytokine,, excitatory transmitter, Ca~(2+) overload and oxygen radical et al.

Adjustments of Second-hand housing policy reduce the deal cost, boosting buyers' expectations; In addition, such change may increase the liquidity of housing, which will speed up investment in new housing and shops. However, the price continue to drop, especially when the new year is coming, more shop investors keep waiting and seeing due to the financial crisis, macro news. Basing on the demand point of view, some demand for living improvement delay the bargain, so did demand for investment due to bad profit-making. As a result, the demand is difficult to start up, while the supply funds is not sufficient, therefore such commercial real estate enterprises will be out of the market due to their inability to meet the finance crisis. Under competitive pressures, the developers will pay more attention to products quality and products differentiation with a view to compete in the market to get a dominant position.

二手房政策的调整降低了购房者的购房成本，刺激了购房期望；另外，二手房政策的改变可能会增加房源的流动性，这样也会加速新房的销售，商铺投资逐渐活跃，但价格表现却成下行趋势，尤其是年关临近，在金融危机面前，商铺投资者多持币观望，从需求者的角度讲，部分改善型需求和投资型需求的购买行为将向后推迟，炒房者将因投机能力下降而不同程度地退出市场，另外，需求难以启动，供给方资金链紧张，部分自有资金不充裕的商业地产企业将面临因无力融资而退出市场的风险，企业因竞争压力大，将更加注重开发产品的品质，提供差异化的产品，以期在市场竞争中占得优势地位。

The conventional "fundamental" explanation for that cycle relates it to political events. The 1973-1974 oil crisis is said to have been due to the cutoff of oil following the Arab-Israeli Yom Kippur War. The 1979-1981 oil crisis is said to reflect the cutoff in oil due to the Iranian Revolution and the Iran-Iraq war. The drop in oil prices after the mid-1980's is said to be due to the collapse of the OPEC oil cartel.

对这个周期的传统的"基本"解释是将它和政治事件联系起来。1973-1974年的石油危机据说是因为阿拉伯－以色列赎罪日战争之后的石油停产。1979-1981年的石油危机据说反映了因为伊朗革命和伊朗－伊拉克战争导致的石油停产。20世纪80年代中期的石油价格下跌据说是因为欧佩克石油卡特尔的崩溃。

Usually it turns into emerald at the time of chromium oxide or vanadium oxide, while aquamarine is formed due to the coloring of ferrous oxide, it becomes verobieffite due to the existence of magnesium, while heliodor is formed due to the coloring of iron oxide.

在存在氧化铬或氧化钒时通常就成了祖母绿，而海蓝宝石则是由于氧化亚铁着色而成的。成为铯绿柱石是由于镁的存在，而金绿柱石则是因氧化铁着色而成的。

The plastic deformation induced due to cyclic rotation of principal stress axes alone can be in the same magnitude as that due to shear with fixed principal stress axes. 2 The volumetric strain due to shearing of cyclic rotation of principal stress axes is found to be composed of a reversible dilatancy component and an irreversible dilatancy component. The former is characterized by its reversibility and is independent of past shear history, the latter by its irreversibility increases with the increase of cycle number yet its increase rate decreases with its accumulation. 3 The obvious non-coaxiality between directions of the principal stresses and principal strain increments is found and its degree depends largely on the change of shear stress component. 4 The intermediate principal stress has considerable effects on the deformation behavior of sands in the condition of cyclic rotation of principal stress axes. The accumulation rate of the irreversible dilatancy component increases with the increase of the intermediate principal stress parameter.
