简介:构造一个煤矿的虚拟景色是的3D为在煤采矿上现代化并且处理信息的客观要求生产。建立“一个数字矿”也是关键技术。由探索当前的世界范围的研究,软件和硬件工具和应用程序要求,与案例研究地点(Pingdingshan煤组的Daz-huang矿)结合了,为一个矿的3Dgeo可视化的一条途径出现工厂和矿车道深深地被讨论。在这研究,虚拟景色基于弧/信息和Site-Builder3D被学习的为一个大范围的快速的建模方法,和从2D景色的3D景色的自动产生被认识到。能从2D把矿车道系统变换成3D的如此的一个自动方法为Dazhuang矿被认识到。一些相关应用程序问题被学习,包括在在矿表面的虚拟景色的虚拟场面种的2D和3D和矿车道之间的属性质问,并列质问,距离措施,碰撞察觉和动态相互作用。一个原型系统被设计并且发展。
简介:陈小春推出他的最新大碟《That’sMine》,收录了10首国语歌及2首广东歌,包括他的最新大热作品《不欢而散》及继《取消资格》后又一苦男人之作《一句到尾》。这张最新的国语专辑,请到和小春认识最深、合作最久的制作人包小松、包小柏、陈子鸿来制作。小春从最早期的FunMusic,一直到上一张"抱一抱"的R&B情歌,再到这张非常具有节奏及音乐性兼顾的《That’sMine》,小春不论是在歌唱的咬字、技巧,甚至对音乐的表现诠释都有很大的进步,就连帮小春配唱的engineer都说小春是所有港星中配合度最高的歌手。专辑中收录的卫视中文台《少林武王》片头曲《下岗一枝花》,是一首首次结合中国精神与西方乐风的骄傲力作;片尾曲《下半辈子》是集结台湾、香港、
简介:二酸矿排水(AMD)样品TS和WK,从在Guangxi省的Dachang充满金属的矿,中国,用基于PCR的克隆被学习途径。44个运作的分类单位(OTU)的一个总数从二件AMD样品被获得。然而,仅仅三OTU(GXDC-9,GXDC-19和GXDC-50)在样品TS检测了能也在样品WK被观察。种系发生的分析表明在二件样品的细菌掉进四个通常认为的部门,它是Nitrospira,Alphaproteobacteria,Gamaproteobacteria,和Acidobacteria。类Acidithiobacillus和Leptospirillum的有机体,在gamaproteobacteria班和Nitrospira家庭上,分别地在二件样品是主导的。在样品TS,它被低pH描绘,高硫酸盐,高铁,和高砷化物,二种(Acidithiobacillusferrooxidans和Leptospirillumferrooxidans)组成了98.22%全部微生物引起的社区。与样品TS相比,在样品WK的微生物引起的社区根据观察是更多样化的。抱持兴趣地,Legionella种类,很少在low-pH环境被观察,在样品WK被检测。这个工作帮助我们进一步理解微生物引起的社区与唯一的地球化学和acidophiles的忍耐能力在极端酸矿排水住在一起到重金属的差异。

简介:现在的学习在Essouk河里调查作文和沉积的矿物学,在近似在上游的2km在黑人Kamber采矿地区在阿尔及利亚的东北定位了Guenitra水库。自从1976,矿被放弃,但是酸的排水水仍然是河污染的来源。粉末X光检查衍射(XRD),与精力扫描电子显微镜学(SEM)散分析(EDX),X荧光分析和红外线的光谱学分析被用来描绘在采矿自河附近在区域在各种各样的地点取样的表面沉积。获得的结果证明沉积的作文被铁和硫主要统治。在矿的附近,jarosite和schwertmannite是必需品猛抛。下游地,沉积被铁oxyhydroxydes的各种各样的阶段与吸附的硫酸盐的存在形成。
