The downshift of diffraction angle of XRD indicates some precious metals enter crystal lattice of LaMnO3, the crystal sizes of catalysts become larger after precious metal loading; BET and SEM results show sintering happened to catalysts after catalytic reaction.

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。

It is shown from the results that the acting force and vibrating acceleration are increased due to its axle load, however, the dynamics interaction between 25 t load wagon and the turnout can be improved by the rubber stack in its axle box, especially in the index such as derailment coefficient, reduction rate of wheel load, opening size of tongue rail and point rail, which is almost equal to the dynamics of 21 t axle load wagon.

结果表明尽管轮轨力和振动加速度因轴重增加而相应增大，但由于25t轴重货车在轴箱处采用橡胶堆，使它与道岔之间的动态相互作用有所改善，尤其是脱轨系数、减载率、尖轨和心轨前端开口量等指标上，与21t轴重货车引起的系统振动值基本一致。

The results indicate that back electromotive force increases with increasing current density and decreases by 0.5 V after adding 2% Li2CO3, the feeding period is 15 min measured by the method of electric potential control. Finally, the Al-Li alloy with the lithium content of 7.93% can be obtained by electrolyzing for 3 h at the current density of 0.62 A/cm^2 and at 680 ℃, and the current efficiency can reach 74.1%.

结果表明，反电动势随电流密度增加而增大，加入2%的Li2CO3可使反电动势降低0.5V；通过控制电位法测得加料周期为15 min：在680℃、电流密度为0.62A/平方公分的条件下持续电解3h，最终制得了理含量高达7.93%的铝锉合金，电流效率可达74.1%。

Although older patients are at increased risk, the frequency of steroid responsiveness with age may occur in a bimodal distribution.

It thinks that the promotion of ESO system is the requirement to deepen the current state-owned enterprise reform and the construction of modern enterprise system. It is urgently needed by the hi-tech enterprises to attract talents and avoid brain drain. The long-term stimulation mechanism such as stock option has better effect in comparison with the traditional salary mechanism such as basic wage and annual bonus. Meanwhile, with the expansion of use scale of the long-term stimulation mechanism such as stock option and greater elasticity of the performance of the whole salary, the stimulation effect of the whole salary will be strengthened.

认为ESO制度的推行是当前深化国有企业改革，建立现代企业制度的要求，是高科技企业吸引人才、避免人才流失的迫切需要；其与基本工资和年度奖金等传统薪酬机制相比，股票期权等长期激励机制的激励效果更好；同时随着股票期权等长期激励机制使用规模的扩大，整体薪酬的业绩弹性增大，使整体薪酬的激励效果增强。
