In order to study the burning of the oil film bearing in high speed wire - rod mill , on - line tested temperature and operating mode of oil film bearing in a domestic framework of finishing mill f15 were determined and a large number of valuable test data were obtained 摘要为了研究高速线材轧机油膜轴承烧损原因，对国内某高速线材精轧机f15机架油膜轴承载荷工况及工作温度进行了在线测试，获得了大量有价值的试验数据。
This thesis discusses the realization of pcbs ict production through a concrete example in which boundary scan technology is applied , and presents a new method to improve the test speed , based on the analysis of boundary scan circuit and means for vector creation . he applys boundary scan ( bs ) to boundary - scan device on the board where bs features by easy vector creation , need less knowledge of the device 本文结合一个具体电路板在线测试实现，首先讨论了在ict中，采用边界扫描元件测试技术实现在线测试生产；并在分析归纳各种测试方法的基础上探索一种新的改进方法，即将deltascan技术与边界扫描技术相结合以减少测试矢量，增加测试速度的一种实用方法。
This article is mostly sets forth deep influence of developing network teaching , the electronics teaching platform ' s general assume , concretely realizing blue print , the system adoptive technology , along with function introduce and implement method of on - line test and answer modules 本文着重论述了发展网络教学的深远影响，以及电子类教学平台系统的总体设想、系统的具体实现方案，实现该系统所采用的技术的介绍，以及在线测试模块、网上答疑模块的功能介绍和具体实现方法。
In order to realize that , one important means is to build up the interaction of network cai and construct reasonable database that can store information such as teaching knowledge , teaching method , study course and information about learner . that is to say , learner can study by way of online study , online discussion , online enquire as well as online test etc study activities . similarly , the system can appraise the study effects of learner and give reasonable study suggestions and navigate to learner 本文认为，实现网络cai的智能化的一个重要手段是增强网络cai的交互性，建立合理的数据库；对教学知识、教学方法、学习过程以及学习者的信息进行的存储和表示；学习者通过在线学习、在线讨论、在线提问以及在线测试等学习活动进行学习，系统能够对学习者的学习效果进行评价并给出合理的学习建议和学习导航。
Both teachers and students can upload , download , search and browse the special - topic resource database ; students learn and reconstruct the learning material with the special knowledge module ; teachers give the homework with the writing module and students use it to do their homework and evaluate others " works : teachers design the test with the online - test module and students use it to test themselves ; with the online special - topic bbs and meeting - room both teachers and students discuss questions ; with the distribution function multi - school can share with each other ' s instructional resources and carry out cooperative learning activities 利用本系统的专题资源库师生可进行专题资源的上传、下载、检索、浏览；利用专题知识模块可在线编辑进行知识重构；利用专题作品创作模块可进行作业的布置、作品的创作及相互评价；利用在线测试模块实现专题相关知识的测评；利用专题讨论区及会议室进行讨论交流；利用分布式功能可进行校际间的协作及资源的共享。
In this paper , not only do we explain our new algorithm , but also we test them by real digital photo , man - made image , video image . furthermore , we compute and discuss the error and its factors . after consulting many references , this paper presents a fast method to count the steel bar of one bundle 文中的研究大部分时间是针对用数码相机在施工现场采集的图像设计的，仅在末期用了较少的几根钢筋进行在线测试，因此，仅就算法而言，还有许多具体的研究、工作去调试、完善和改进，如果再进一步结合嵌入式硬件和生产管理的需要，形成一个较成型的产品，则需要做更多、更深入的研究。
On the one hand , according the design principle of torque sensor , this paper researched the non - contact torque sensor , which base on the theory of electric resistance strain and the rotation transformer and could satisfied the request of our project as well as the condition of the producing process . on the other hand , the modulation method of torque signal has been solved before the signal was input to the industry computer , therefore , solved the problem of signal transfers 其次，研究和研制了扭矩在线测试工作所需要的仪器硬件。一方面，根据扭矩传感器的设计原理，研制了满足课题要求和生产现场条件的，基于电阻应变理论和电感集流环的非接触型扭矩传感器；另一方面，制订了扭矩信号在输入工业计算机之前的调理方法，解决了信号传输问题。
