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。

The structure measurement indicates that only a small amount of Bi3+ ions can not enter the A-site of La2/3Ca1/3MnO3 lattice. Because of the low melting behavior of bismuth oxide, the superfluous Bi will segregate as insulating bismuth oxides and bismuthate. Because of the segregation of Bi, the surface of the main phase has different ferromagnetic property from that of the core, namely the magnetic inhomogeneity of the samples is enhanced, which results in the broader ferromagnetism-paramagnetism transition and magnetoresistance plateaus in samples with the high Bi content.

结构测试表明Bi并不能进入La2/3Ca1/3MnO3的晶格锰位，由于A位元素的过量和铋氧化物的低熔点特性，烧结过程中Bi元素析出形成了绝缘性的第二相；并且Bi的析出导致样品主相的表面存在与主相体心磁性质不同的铁磁相，即样品的磁不均匀性增强，使得高Bi含量的样品表现出宽的铁磁-顺磁转变和磁电阻平台效应。

The demonstrate in can asking to develop a process of course (safeguard a map by development staff for example, a of the ID interfacial element and tiring-room or correspondence of a group of operations rises), what I need to solve now is how to let the system discovers automatically and maintain these relationships Read above oneself problem, discovery had a direct result to be told to the system,"Authority " the ID that is an interface element and the URL that a group of tiring-room serve (take no account of data to visit attributive temporarily), attributive ={id, comId, urls, desc} such, how can problem translate into realize the definition of attributive, let him user input ComId, Urls?

当然可以要求开发过程中指明（例如由开发人员维护一个映射，把界面元素的ID和后台的一个或者一组操作对应起来），我现在需要解决的是如何让系统自动发现和维护这些关系读了上面自己的问题，发现有了个直观的答案对于系统来讲，&权&就是一个界面元素的ID和一组后台服务的URL（暂时不考虑数据访问权限），权限={id，comId，urls，desc}这样，问题转化为如何能够实现权限的定义，让用户自己输入comId、urls吗？

But after about a month to restore the root system, the leaves of nitrogen, phosphorus and potassium contents in treatment 5, 6, 7, 8, 2 gradually higher than the control. This is because the absorption of fertilizer during this period shown to promote on the elements, and with the passage of time the processing elements continue to be reduced to a leaf until the latter part of the growing season is also higher than the control.3.The pH value in rhizosphere soil of treatments poplar plantation were lower than that in non-rhizosphere soil, but the content of organic,available nitrogen, phosphorus, potassium, utility cuprum and utility zincum were all higher than those in non-rhizosphere soil.

但是经过大约一个月的根系恢复，处理5、处理6、处理7、处理8、处理2叶片中的N、P、K逐渐高于对照，这是因为施肥对元素的吸收在这一期间开始表现出了促进作用，并且随着时间的推移各处理中元素含量持续降低至落叶，直至后期的生长季节也高于对照。3、各处理的杨树林地根际土壤pH值均低于非根际土壤，而有机质、碱解氮、速效磷、速效钾、有效铜和有效锌的含量均高于非根际土壤，与其它处理相比，80cm两侧断根施肥处理的根际土和非根际土壤速效养分含量最高，差异达显著水平。
