( 7 ) in the hot dry rock geothermal energy extraction system , the fracture width widen gradually with the heat extraction , after the system start to operate , in a month the width change rapidly , the growth rate exceed 100 % , and then the change become even , until 3 year , the variety is very small , almost towards to stability ( 7 )在高温岩体地热开发中,其裂缝宽度是随地热提取而逐渐加宽的,在开始运行的一年内,宽度增长迅速,其增长率达到100 %以上,然后变得平缓,到3年后,变化很小,几乎趋于稳定。
Mtrcl has advised us that such retrofitting works cannot be advanced as they involve major alterations to the stations , and the tunnel ventilation , air - conditioning and smoke extraction systems . added to the complexity of the works is the need to carry out the works during the non - operating hours between 2 am and 5 am 地铁公司表示由于工程涉及车站及隧道通风系统、冷气系统及抽风系统的重大修改,因此未能提早完成。此外,所有工程只能在非行车时间内即凌晨二时至五时期间进行。
In this paper , according to the approach and engineering reality condition , an semantic based information extraction system has been designed and wrote some codes and implemented the system , so in this paper , the main frame and the designing method of main modals in detail are introduced 根据上述方法并结合工程实际情况,设计了一个基于语义的信息抽取系统。在本文中,提出了基于语义的信息抽取系统的总体框架、各主要模块的设计,还着重说明了基于语义的信息抽取方法。
In cbt courseware development platform , many function and application are supported by multimedia knowledge database . the text language knowledge is the most basic knowledge form , so text knowledge automatism extraction becomes the key technique in the cbt courseware development . the paper mostly introduces how the knowledge extraction system is designed and realize in the cbt courseware development 在cbt ( computerbasedtraining )课件开发平台中,很多的功能和应用都是以多媒体知识库为后台支持的,其中文本语言知识是最基本的知识形式,因此文本知识自动抽取成为cbt课件开发中的关键技术之一。
The conventional methods for mining such seams including the longwall blasting and block caving suffer form the drawbacks of being low in recovery , high in labor intensity and low in efficiency . after shifting to the use of the fully - mechanized extraction system by the zhaogezhuang branch mining industry co . of kailuan ( group ) co . , the mining of the pitching seams has met with remarkbable social and economic result 针对大倾角煤层长壁炮采、落垛等采煤方法,存在回采率较低、员工劳动强度大、高产高效受限及安全等诸多问题,开滦(集团)赵各庄矿业分公司在探讨大倾角煤层采煤工艺的改革及实践大倾角煤层综合机械化采煤过程中,取得了较好的社会经济效益。
By wisely choosing data sources that are reliable and picking anchors within those sources that are tied to content and not format , you can have a low - maintenance , reliable data extraction system , and , depending on your level of experience and the amount of data to extract , you could have it up and running in less than an hour 通过明智地选择可靠的数据源以及在这些数据源中选取与内容相关但与格式无关的锚,可以使您拥有一个维护成本低廉,可靠的数据抽取系统。并且,根据经验级别和要抽取的数据量,您可以在一小时之内就能安装与运行它。
