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。

Such a conception is to be sharply distinguished,therefore,from certain legal fictions or presumptions which have no relation to fact and are often in truth false deductions or conclusions—such as the fiction of a lesase in the old suit of ejectment,the fiction by which the english Court of Exchequer usurped jurisdiction by permitting an allegation that the plaintiff was the King's debtor and an then allowing no one to deny it,the fiction that all of the stockholders of a corporation are residents of state where it was incorporated,the fiction of a lost grant and the like.Such fictions or presumptions are obviously purely arbitrary and are often in truth contrary to fact,and were invented by the courts for the perpose of being able to administer justice without expressly disregarding a rule which literally applied would produce results opposed to justice.

As to the doctrine called the Real Presence,[22] the council condemns: those who, denying that Jesus Christ, God and Man, is truly, really, substantially present in the sacrament of the Holy Eucharist, hold instead that He is only present as in a sign or image or manifestation of power; those who say that the substance of the bread and the wine remains along with the body and blood of Christ, denying that marvellous and unique changing of the whole substance of the bread into the Body and the whole substance of the wine into Blood, while the appearance of bread and wine still remain--the change which the Catholic Church most suitably calls Transubstantiation; those who say that the Body and Blood of Christ is not there following upon the consecration, but only while the sacrament is in use, while it is being received, that is to say, but not before this or after this, and that in what is left over of the consecrated hosts or particles after communion has been administered, the true Body of the Lord does not remain; who say that the main fruit, or the sole fruit, of this sacrament is the forgiveness of sins; or that Christ the only begotten son of God is not to be adored in this sacrament with the externals of the reverence called latria,[23] and that those who do so adore Him in this sacrament are idolaters; that Christ is shown forth in this sacrament to be received in a spiritual manner, and not also sacramentally and really; that only faith is sufficient preparation for receiving this most holy sacrament.

随着社会的发展,交通工具的使用越来越普及,随之而来的是交通事故大幅度增长。刑法对严重的交通肇事行为确认为犯罪,对行为人进行刑事处罚。但是在现实中,对交通肇事涉嫌犯罪的初步认定依赖于对人员伤亡、财产损失以及事故责任的认定。而这些因素对犯罪嫌疑人的定罪与量刑具有决定性的意义。同时,在对交通肇事进行刑事追究的司法实践中,存在诸多与交通肇事罪发生竞合的情形,对此也应进行明晰。

The following main results are obtained: The TiO_2 photocatalyst with small crystallite size, high surface area, narrow and uniform pore size distribution, and microporous frameworks could be prepared out by applying MW radiation in the preparation process. The microwave-induced fluorescence technique verified for the first time that microwave enhanced the formation rate of hydroxyl radical, leading to the increase in the photocatalytic efficiency. Compared with the conventional catalyst, TiO_2 prepared by MW dielectric heating owns a higher UV absorption ability, and its optical absorption edge and photovoltaic response are shifted toward the short wavelength region, resulting in increase of photooxidation efficiency. The photocatalytic conversion and the mineralization ratio of acetaldehyde are increased respectively by 30% and 40% over the TiO2 prepared by MW radiation when compared to the TiO2 prepared by the conventional heating. For the MW-assisted photocatalytic reaction over the MW-prepared TiO2, production of hydroxyl radicals is enhanced by 22.5%, and the photocatalytic conversion is accordingly increased by 20%. Similarlly, applying MW also increased the photocatalytic conversion and the mineralization ratio of acetaldehyde over TiO2/Al2O3 sample.
