Development on gastric motility information extracting system 现场可编程门阵列动态重构下的低功耗研究
Failure reasons of impellers in a pump of an aromatic hydrocarbon extracting system were analyzed by means of microcoulometric detector , spectroscopic methodology , optical microscopy , scanning electron microscope and x ray diffraction 摘要采用微库仑法、光谱法、光学显微镜、扫描电镜、 x射线衍射仪等手段对芳烃抽提系统的3105泵叶轮进行了失效分析。
The extract process have three steps : constructing echg of java system from java profile , extracting system ' s lexical relational model by scanning source code and analyzing the polymorphism calling location , constructing the semantic model by rule - based model mapping of lexical model 抽取过程有三个阶段:构造系统的echg ,扫描程序的源代码和多态点分析得到系统的词法层次模型,通过基于规则的推理转换词法模型为语义模型。
Secondly , five modules which include system general design , the coordinates extracting system , the coordinates data management , the automatic production of tables and the system interface design were mainly introduced . while the design process and algorithm realization of each module were discussed in detail 其次主要介绍系统总体方案设计、坐标提取系统、坐标数据管理、坐标表自动生成、系统界面5个子模块,对各个模块的设计过程和算法实现进行了详细阐述。
The article discusses the main problems of creating web database data publishing and information extracting system based on xml at present , combing the characteristic of traditional database and xml . and it designs a prototype system on the research of the transition from database to xml information and their publishing methods . it also gives us a specific explanation of the key problems , such as related transition , processing of xml data on web server side and extracting information from the xml data . it comes out with the conclusion that web database data publishing and information extracting based on xml has its applied basis 论文结合传统关系数据库和xml各自特点,在数据库到xml的数据转出、 xml数据发布、信息提取这三大模块的基础上设计了一个系统原型,并针对目前设计一个基于xml的web数据库数据发布及信息提取系统的主要问题进行了探讨,对研究过程中提出的关系数据库到xml数据的“相关转出” 、 xml转出数据的web服务端处理、 xml数据的提取等问题和关键解决思路、技术方法做了较为详细的阐述。
Constructing cdna expressing library of erythrocytic plasmodium falciparum from hainan : the total rna was obtained by using . triplix kit . a modified oligo ( dt ) primer ( cds ffi pcr primer ) was used in the single - stranded ( ss ) dna synthesis reaction . the ss - dna was reversely transcripted from total rna . double - stranded ( ds ) cdna was amplified by long - distance ( ld ) pcrafter the digestion with proteinase k and sfi i , the cdna with no less than 200bp was collected and purified by glass - milk kitthe library was constructed after the ligation of cdna to tiplex2 phage particle packaged with the packaging extract system in vitro . a high titer and high recombinant ratio of cdna library was constructed 构建恶性疟原虫海南株红内期cdna表达文库提取红内期恶性疟原虫海南株总rna ,直接以总rna为模板使用cdna文库构建试剂盒,首先反转录合成ss一dna ,再扩增合成ds一dna ( cdna ) ,对扩增产物用蛋白酶k消化及左z丁i酶切,抽提蛋白、去除rna后,用玻璃奶试剂盒纯化、回收20obp以上的片断,经与载体连接再用蛋白包装物包装后形成未扩增文库,最后扩增完成恶性疟原虫海南株红内期cdna表达文库的构建。
For the remaining eight at - gradeoverhead stations ( tseun wan , kwai hing , kwai fong , ngau tau kok , kowloon bay , kwun tong , heng fa chuen and chai wan ) , retrofitting of platform screen doors involves major alterations to the stations and tunnel ventilation , air - conditioning and smoke extract systems . since such at - gradeoverhead stations are not designed with air - conditioning and ventilation systems , retrofitting works are subject to technical constraints 至于其馀8个现时没有月台幕门的地面及高架车站(即荃湾、葵兴、葵芳、牛头角、九龙湾、观塘、杏花?及柴湾) ,加装月台幕门系统须涉及重大工程,包括车站及隧道通风系统、冷气系统及抽风系统等的大型修改工程。
