More horizontal well drilling process CBM branch of horizontal Wells and well integrated in the cave of the branch, and drilling well connected eye, gas underbalance pressure drilling and geological guidance technology, is a high difficulty in construction of system engineering. But the main performance advantages in the single well gas production, high recovery is high, the production cycle is short, drill cover an area of an area small, but must be adopted with geological conditions of the different type of horizontal Wells branch, its economic benefits and social benefit is different, so much used in medium and high coal rank coal seam, high mechanical strength of coal seam and the mechanical properties stability; Geological condition requirements buried depth moderate, thickness of coal seam moderate, horizontal continuous stability distribution, coal gangue placed not development, structure stability, avoid faults and fracture zone. At the same time in order to maintain the stability of coal seam shaft, coal seam of slimhole drilling for general use (15.2 ㎝), so for drilling tools, measuring instruments and equipment performance and so on are out new requirements. More horizontal well drilling process CBM branches facing the main difficulties have: coal seam is fragile, and development of mutually perpendicular natural fractures, in this fragile strata of drilling, extremely easy cause underground collapse, stuck drill, even borehole scrap such complex accident; Coal seam is susceptible to pollution, reservoir protection is difficult, generally USES the inflatable drilling fluid, foam or formation water as coal seam segment of the drilling fluid system; Because more shallow buried coal seam, borehole curvature is bigger, drilling pressure to meet requirements, drill level well drilling column branch unlikely to occur fatigue damage, which led to the complexity in case; More horizontal well drilling process CBM branch belongs to new drilling process, involving many new tools and instruments. For example, for the two Wells connected electromagnetic measurement device, the small size of the geological oriented tools and efficient friction reduction short sub and so on, at the moment the equipment and instruments in China is still lacking.

搜索和挖掘数以万亿计的时间序列子序列在动态时间扭曲文摘大多数时间序列数据挖掘算法利用相似性搜索核心子程序,因此相似性搜索所花费的时间瓶颈的几乎所有时间序列数据挖掘算法。的难以扩展搜索大型数据集很大程度上解释了为什么大多数学术工作时间序列数据挖掘已经停滞不前考虑几个数以百万计的时间序列对象,而大部分工业和科学坐在数十亿时间序列对象等探索。在这项工作中,我们表明,通过使用一个组合四个小说的想法我们可以搜索和我真正的大量时间第一次系列。我们将演示以下极直观的事实,在大型数据集,我们可以搜索下比当前最先进的DTW要快得多欧几里得距离搜索算法。我们展示我们的工作史上最大的一组时间序列的实验。在特别地,我们认为大于最大的数据集结合所有的时间序列数据集的大小考虑在所有数据挖掘论文发表。我们表明,我们的想法让我们解决高层次的时间序列数据挖掘主题等问题发现和聚类在尺度,否则站不住脚的。除了采矿大规模数据集,我们将展示我们的思想也有影响的实时监控数据流,使我们能够处理更快的到达率和/或使用更便宜,比目前更低的设备可能的。

搜索和时间序列挖掘万亿子序列下的动态时间规整摘要大多数的时间序列数据挖掘算法使用的相似性搜索是一个核心子程序,从而为相似性搜索的时间是几乎所有的时间序列数据挖掘算法的瓶颈。的缩放搜索到大型数据集的困难在很大程度上解释了为什么时间序列数据挖掘已趋于稳定,大多数学术工作考虑到数以百万计的时间序列对象,虽然工业与科学坐在数十亿的时间序列对象的等待为探讨。在这项工作中,我们表明,通过使用一个组合四种观点我们可以搜索我的真正大规模的时间对于第一个时间序列。我们证明以下极非直观的事实;在大型数据集,我们可以准确地搜索下DTW的速度远远超过目前的国家的最先进的欧氏距离搜索算法。我们证明我们的工作时间序列实验曾试图最大的集。在特别是,我们考虑的是最大的数据集大于所有的时间序列数据的所有数据考虑组合大小论文发表过挖掘。我们证明了我们的思想,让我们解决更高级别的时间序列数据挖掘问题,如主题发现和尺度,否则将聚类站不住脚的。除了挖掘海量数据集,我们将展示我们的思想也为实时监测的影响数据流,使我们能够处理更快的到达率和/或使用比目前的价格和较低的动力装置可能的。

With the continuous advance of China's Higher Education, university enrollment gradually expand the scale of expansion of enrollment resulting from the cumulative effect of gradually released. Tight supply and demand is what makes the difficult problem of employment of college graduates have become increasingly prominent, while the employment of female graduates is even more difficult. Female college students to explore and analyze gender discrimination in employment, female college students not only how to answer the difficult problem of employment, but also to create employment, gender equality, environment, building an advanced culture of gender significant. In this paper, survey methods to understand, Zhangzhou Teachers College, the employment situation of female college students, and focus on gender discrimination in employment to study and explore.

人工翻译,请放心采纳。在动态时间规整下搜索和挖掘数以兆计的时间序列子序列摘要:大多数时间序列数据挖掘算法都采用相似性搜索作为核心子程序,因此相似性搜索所花的时间对几乎所时间序列数据挖掘算法来说都是瓶颈。将搜索扩展到大型数据集的难度很大程度上解释了为什么对时间序列数据挖掘的大多数学术研究一直停留在考虑的几百万个时间序列对象的平台上,而很多产业和科学却有数以十亿计的时间序列对象等待着进行探索的原因。在本文中,我们表明了,通过使用四种新想法的结合,我们可以首次搜索和挖掘真正大量的时间序列。我们证明了以下极为直观的事实,在大型数据集中,我们可以准确地在DTW(动态时间规整)下,比目前最先进的Euclidean距离搜索算法快得多的进行搜索。我们演示了我们对迄今试图进行的最大时间序列集的试验所做的研究工作。具体而言,我们考虑的最大的数据集比在所有迄今出版过的所有数据挖掘论文中加以考虑的所有时间序列数据集的总和规模还要大。我们证明了,我们的想法使我们能够解决高层次的时间序列数据挖掘问题,比如在否则将站不住脚的规模上进行主体发现和集群。除了挖掘大量数据集,我们将证明,我们的想法也有实时监控数据流的含义,从而使我们能够处理快得多的到达速率和/或使用比目前可能的更便宜,更省电的设备。

摘要“MADEINCHINA”中国制造,是中国经济的骄傲,也是全球经济链条中的关键一环,制造业作为我国的支柱产业,为我国经济的发展和增长做出极大的贡献,对我国经济有着举足轻重的作用和地位,靠着物美价廉的中国商品,中国的GDP攀上了世界第四的位置。国外的消费者享受到了低价格、高消费的生活,但是,在劳动力成本增加、原材料价格不断上涨,物流成本未得到有效控制、人民币汇率节节走高、银行利率上升,出口政策调整等的环境下,传统的中国制造也遭遇到了前所未有的压力,昔日低价廉销策略难以为继,中国制造业来到了一个十字路口。中国制造何去何从?是近来非常热的一个话题,在这样一个大背景下,对中国制造危机进行研究具有重大的意义。文章分为六个部分进行论述:第一部分对中国制造进行了概述,介绍中国制造与世界工厂以及中国创造的关系。第二部分介绍中国制造业工业化进程以及发展的模式和发展方向,第三部分从中国外贸结构的弊端和国内外宏观经济的变化分析危机产生的原因。第四部分从出口增长速度、竞争力等方面说明危机对中国出口的影响。第五部分主要针对第三部分的原因分析提出相应的对策。第六部分主要对中国制造的未来进行了展望,在文章的最后得出一个结论:中国制造要做强必须要调整产业结构和增长方式。 关键字:中国制造 支柱产业 十字路口 危机 对策 Abstract "MADEINCHINA" China is the pride of the Chinese economy as well as the global economic chain, a key element in the manufacturing sector as a pillar industry in China, for China's economic development and make a significant contribution to the growth of China's economy has a significant the role and status, relying on inexpensive Chinese goods, China's GDP climbed the world's fourth position. Foreign consumers to enjoy low prices and high cost of living, but an increase in labor costs, rising raw material prices, logistics costs have not been effectively controlled, the RMB exchange rate steadily higher, bank interest rates, export policy adjustments, such as the environment , a traditional Chinese manufacturers also face unprecedented pressures, inexpensive low-cost marketing strategies used to sustain China's manufacturing sector came to a crossroads. China go from here? The recent very hot topic, in such a background, to study the crisis in China is of great significance. Part of the article is divided into six topics: the first part of an overview in China, China manufacturing and the creation of the world's factory as well as China's relationship. The second section describes the process of industrialization of China's manufacturing industry and the development of the model and the development direction of China's foreign trade from the third part of the structure of defects and changes in domestic and international macro-economic analysis of the causes of the crisis. Part IV from the export growth rate, competitiveness and other aspects of the crisis on China's exports. Part V of the third part of the main reasons for the analysis of corresponding countermeasures. Part VI of the main manufacturer of China's future prospects, in the article, finally arrive at a conclusion: China must be strong to do adjust the industrial structure and growth mode. Keywords: pillar industries in China at the crossroads of crisis response
