This paper presented a new-type CNC curve grinding machine, in order to conquer the disadvantages of conventional NC curve grinding machine and improve surface quality, dimensional accuracy and machining efficiency. The new-type grinder adopts some high and new technologies: ① the normal tracing device could make grinding wheel coincide with the normal direction of the machining points in work piece, and improve surface quality and dimensional accuracy; ② the digital image on-line recognition system could monitor machining process and compensate wheel wear in real time; ③ linear motor drive mechanism could realize the exact adjustment of the grinding head digitally and increase the machining efficiency. The math models of normal tracing and circular tolerance zone were presented. The experimental results show that the new-type CNC curve grinding machine equipped with the three devices mentioned above is easy to realize the precision grinding of any complex curve, and improve surface quality, dimensional accuracy and machining efficiency. 展开更多

A feature extraction and fusion algorithm was constructed by combining principal component analysis(PCA) and linear discriminant analysis(LDA) to detect a fault state of the induction motor.After yielding a feature vector with PCA and LDA from current signal that was measured by an experiment,the reference data were used to produce matching values.In a diagnostic step,two matching values that were obtained by PCA and LDA,respectively,were combined by probability model,and a faulted signal was finally diagnosed.As the proposed diagnosis algorithm brings only merits of PCA and LDA into relief,it shows excellent performance under the noisy environment.The simulation was executed under various noisy conditions in order to demonstrate the suitability of the proposed algorithm and showed more excellent performance than the case just using conventional PCA or LDA. 展开更多

In this thesis, the design in construction management is defined as the design meets the requirements of the constructor. There are a range of definitions of design, but in this paper "design" refers to something, which has been planned and made and a pattern for decorating in something in the term of construction. Rumane says (2010)the design involves two processes. The first thing is analyzing and designing components and structure on the basis of recognized codes and standards of safety. The other is that designers conduct the information in the form 展开更多

A recognition algorithm was designed to get information of turn light. Approximated center segmentation method was designed to divide the front vehicle image into two parts by using geometry information. The number of remained pixels of vehicle image which was filtered by the morphologic feaatres was got by adaptive threshold method, and it was applied to recognizing the lights flashing. The experimental results show that the algorithm can not only distinguish the two turn lights of vehicle but also recognize the information of them. The algorithm is quiet effective, robust and satisfactory in real-time performance. 展开更多

也谈禁止词“别”的来源

"别"是明清以来北方汉语中常见的表禁止的否定副词。对"别"的来源和产生途径以往有多种看法,本文在前人研究基础上,通过综合考察历史语料和语音变化,尝试提出一种新的补充性解释,认为"别"的产生途径可能是"不要"变音为"别要",然后省缩为"别"。其完整过程经历三个阶段:(Ⅰ)词汇化:从"不""要"连用,词汇化为表禁止的"不要";(Ⅱ)词音变化:"不要"变读为"别要"("别-"是"不-"的变音);(Ⅲ)省缩:"别要"省缩为"别"。 展开更多
