无法利用

• Briefly , we introduce the research areas and methods of data mining . there are enormous data accumulated accompanying with the application of cims . interested patterns are more imperative in the field of database
  3 .整体讨论了数据挖掘技术的研究领域和方法，针对当前cims系统中，数据充足但是无法利用的问题，将olap和数据挖掘技术引入cims系统中，发掘系统中潜在的有价值模式，为用户创造更大的利润。
• Because the field caused by the eddy - current transducer in the dissertation is not only axially symmetrical , but also plane symmetrical , there is no normal component of the electrical field strength and we cannot apply the condition en = 0 to solve such a problem
  由于本文中的涡流传感器模型，其电磁场不仅是轴对称场，而且还是平面对称场，不含有电场强度的法向分量，所以无法利用边界条件e _ n = 0来求解。
• They attracted less suspicion in enemy territory than men , and although they usually lacked the necessary background for reporting technical data , they were often able to extract otherwise - unavailable knowledge of german military intentions from enemy officers
  他们比男性较少引起敌人怀疑，尽管如此，他们往往缺乏必要的报告技术数据的经历，除此之外他们可能从敌人办公室提取到是些无法利用的德国军事意图的数据。
• The on - line chinese character recognition system , which accepts on - line inputs , utilizes a great amount of information such as the stroke order ; write pressure and other information , while the off - line chinese character recognition does not have such information so it faces a little difficulty
  由于文字在线识别的对象是在线输入的文字,所以它能够利用笔画顺序、书写轻重等重要信息。而文字离线识别则无法利用这些信息,所以要面对一些新的困难。
• Since the developing time of security market is still rather short , the data accumulation is lacked . in addition , the industry has a high level of privacy , except the season report or year report required by law , data are not made public , so the writer could not analyze them by quantitative method , thus making the article lack of vertical and horizontal comparison
  由于我国证券市场发展的时间相当短，原始数据积累的很少，再加之目前基金行业私密性较强，除了法律规定的季报、年报外，数据几乎不对外公开，也鲜有这方面的研究报告，故无法利用数量统计的分析方法进行采样分析，使得文章在基金的纵向、横向比较方面的研究力度不够。
• Ammonifiers in suzhou creek can not use inorganic nitrogen and carbamide as nitrogen source ; additional carbon source and garbage lixivium have little influence on ammonifiers growth ; high content of salt and low temperature restrain ammonifiers growth ; alkalescent condition has little influence on ammonifiers , but acidic condition restrain ammonifiers growth ; the biomass of ammonifiers are not necessary correlated with the function of ammonifiers , adding glucose with 1g / l content into the water sample obviously promote the growth and function of ammonifiers . physiological groups of bacteria play significant role in the translation and
  苏州河的氨化菌无法利用无机氮和尿素作为氮源；在营养条件充足时添加额外c源和富含有机物的垃圾浸出液对氨化菌的生长基本无影响；高盐度和低温抑制氨化菌生长；碱性条件对氨化菌的生长影响不大，酸性条件对氨化菌生长具有抑制作用；氨化菌生物量的消长与转氨活性之间不存在必然联系， 1g / l的葡萄糖对苏州河水样中氨化菌的数量和转氨功能具有明显的促进作用。
• After almost one year research and analysis on chinese garment enterprises , finding that there are three main issues in gsgcad : lack of network / internet oriented , cannot sharing and communicating garment structure graphics design resource with outside world ; lack of intelligentization , cannot use former design experience as reference , leading to low design efficiency ; low commercialization degree
  经过近一年对服装企业的调研分析发现：当前，服装结构图形辅助设计子系统主要存在以下三方面原因：缺乏网络化，无法与外界设计资源交流与共享；缺乏智能化，无法利用以往设计经验指导设计，设计效率较低；商业化程度较低。
• You can use self - certs to deploy clickonce applications with high trust on an intranet ; however , when these applications run on a client computer , clickonce will identify them as coming from an " unknown publisher . " by default , clickonce applications signed with self - certs and deployed over the internet cannot utilize trusted application deployment
  可以使用自发证书在intranet上部署具有高信任级别的clickonce应用程序；但是，当这些应用程序在客户端计算机上运行时， clickonce会将它们标识为来自“未知发行者” 。默认情况下，用自发证书签名并通过internet部署的clickonce应用程序无法利用受信任的应用程序部署。
• So it is solved not to describe the related - data query in standard sql . using rdsshd - xml db programmers only input all relevant connection information and proper sql statement about the query on the calling principle supplied by rdsshd - xml , they can perform their query in so simply way
  为处理异构数据库的关联数据查询，课题利用了xml描述数据的优越性，设计了基于xml的查询模式，此模式描述了异构数据库查询的所有相关信息，解决了异构数据库的关联数据查询无法利用标准sql来描述的问题。
