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 the first important step in video analysis and will directly affects the effectiveness of indexing Shot boundary detection is one of our major research interests and we will tackle the following existing problems the ambiguity between gradual change and camera motion, the discontinuity during gradual change, false detection caused by illumination variation and flashlight, automatic threshold selection Firstly, we discuss shot boundary detection in non-compressed domain In chapter 2, we compare some of the commonly used detection methods which are based on frame difference and point out that single feature will not generate good results As a conclusion, we use fuzzy logic to combine multiple features Presently, most frame difference based shot boundary detection algorithms rely on threshold and hence the selection of such thresholds will greatly affect the performance of boundary detection We propose a membership function to define frame difference and calculate the membership with self adaptation according to the statistic distribution of frame differences to satisfy different type of video clips Experiments show that the proposed fuzzy shot boundary detection algorithm can be used with different video types and has a high detection precision and recall In chapter 3, we discuss model-based shot boundary detection algorithms regarding chromatic and spatial editing effects such as fade-in, fade-out, dissolve and wipe Various parameters are proposed to better describe the characteristics of each editing type.
镜头边界的检测是把视频自动地分割为一个个镜头,作为基本的索引单元,因此它是视频分析重要的第一步,直接影响到视频检索的成败。镜头边界的检测是本文研究的重点之一。目前镜头边界检测算法主要存在以下问题:渐变与镜头运动难以区别;渐变过程中的不连续与停顿、光照条件的变化及闪光灯等特殊情况会引起误检测;自动选择阈值比较困难等。本文首先针对非压缩域视频进行了镜头边界检测的研究。在第二章中我们采用了比较流行的基于帧间差的方法。在比较各种帧间差计算方法的基础上,指出使用单一的特征难以取得很好的检测效果,提出用模糊逻辑综合使用各种特征。目前大多数基于帧间差的镜头边界检测算法都采用阈值法进行镜头转换的判别。阈值选择的误差对检测性能有较大的影响,本文提出用隶属度函数定义帧间差较大、中等较大和较小等概念,并根据帧间差的统计分布自适应地确定隶属度,以适应不同类型的视频片断。实验结果表明这种基于糊逻辑的镜头边界检测算法可以适应不同的视频,并具有较高的检测精度和检出率。在第三章中采用基于模型的方法进行镜头渐变的检测,研究了淡入/淡出、慢转换和扫换的模型。

The results showed that: the influence of the aquaculture process on aquaculture water determined by type of aquaculture; the influence of aquaculture process on the water temperature, salinity and pH value were not wide.the descent of pH value was related to feed coefficients ; the dissolve oxygen of water in outfall was lower than the water in infall,but the concentration still maintained at the saturation level, is mainly affected by density of aquaculture ,rate of feed and artificial measures of increasing oxygen ;the major form of inorganic nitrogen was nitrate-N;the concentration of inorganic nitrogen and the organic matter tended to increase ,but the ammonium to decline ,this was relation with density of aquaculture ,rate of feed and variation of the different inorganic nitrogen form ; concentration of phosphate-P was low in outfall of pond , related with phosphate-P precipitating, as flowing water speed slowly in outfall;This phenomenon that the total number of bacteria and coli form group of water in outfall was lower than the water in infall , this caused by measures of sterilization and disinfection .
结果表明:养殖过程对水体影响与养殖类型有关。养殖过程对水体的水温、盐度和pH影响不大; pH下降与饲料系数高有关;溶解氧含量排水口比进水口低,但仍维持在饱和状态,与养殖密度、投饵率和人工增氧有关。硝酸氮是无机氮的主要存在形式,无机氮和有机物含量有升高趋势,氨氮有下降的趋势,与养殖密度,投饵率和各种无机氮之间的相互转换有关。活性磷酸盐含量在排水口含量下降,与排水口流水速度慢,磷酸盐沉淀有关。生物指标细菌总数和大肠杆菌总数在排水口比进水口低现象普遍存在,这与养殖场杀菌消毒等措施有关。

Thus, in every American deliberative assembly having no rules for conducting business, the motion to adjourn, when it does not dissolve the assembly, would be decided to be undebatable, as in Congress, the English parliamentary law to the contrary notwithstanding; so if the previous question were negatived, the debate upon the subject would continue, as in Congress, whereas in Parliament the subject would be immediately dismissed; so, too, the previous question could be moved when there was before the assembly a motion either to commit, or to postpone definitely or indefinitely, just as in Congress, notwithstanding that, according to English parliamentary law, the previous question could not be moved under such circumstances.
认真地探究人的智慧本质,他和大多数西方哲人一样,发现人是一种最难被道理说服的动物。当发生分歧的时候,不管分歧的基础是什么,或者出于利益冲突,或者出于信仰理念,或者出于知识经验的不同,反正一旦分歧明确公开,是非常难以在短短几个钟头或几天里靠语言的交流来达到一方说服一方的。分歧的双方找到共同点的可能不是不存在,但是这需要有一定的交流机制,否则,一方说清楚了,另一方根本没听进去,还是白搭。
