中国戏曲中的美——昆曲的艺术魅力及昆曲的传承与革新

以昆曲的艺术魅力为主线就昆曲的传承与革新问题提出几点思考。昆曲是我国一种古老的戏曲剧种,它的剧目丰富,曲调婉转,表演优美动人,是中国古典戏曲的代表。在“流行”已逐渐成为人们审美定势和思维习惯的现今社会,昆曲在中国传统文化轨道中将如何生存和健康地发展,是摆在戏曲界的一个问题。     

Liquid Flow in Shaped Fiber Bundle

By computation and comparison of the critical spreading coefficient parameter, it was found that shaped fiber bundle is better for wetting. Liquid-air interface tension of liquid arising the shaped fiber bundle body is considered as one critical factor besides liquid viscosity, inertia force and liquid-fiber interface tension. Experimental result simulation demonstrated that the liquid-air interface tension is correlated with the geometric size of the liquid arising in body, Φ0 （x） and which is affected by the cross sectional shape of fiber and the radius of single fiber. The shaped fiber bundle model is/ntroduced to/nvestigate liquid flow in fiber assembly. The model is generated based on a random function for stochastic forming of fibers in bundle and it is necessary to combine this fundamental model with physical explanation for investigation of liquid flow in fiber assembly.     

Techniques of Image Processing Based on Artificial Neural Networks

This paper presented an online quality inspection system based on artificial neural networks. Chromatism classification and edge detection are two difficult problems in glass steel surface quality inspection. Two artificial neural networks were made and the two problems were solved. The one solved chromatism classification. Hue, saturation and their probability of three colors, whose appearing probabilities were maximum in color histogram, were selected as input parameters, and the number of output node could be adjusted with the change of requirement. The other solved edge detection. In this neutral network, edge detection of gray scale image was able to be tested with trained neural networks for a binary image. It prevent the difficulty that the number of needed training samples was too large if gray scale images were directly regarded as training samples. This system is able to be applied to not only glass steel fault inspection but also other product online quality inspection and classification.     

Combined Density-based and Constraint-based Algorithm for Clustering

We propose a new clustering algorithm that assists the researchers to quickly and accurately analyze data. We call this algorithm Combined Density-based and Constraint-based Algorithm （CDC）. CDC consists of two phases. In the first phase, CDC employs the idea of density-based clustering algorithm to split the original data into a number of fragmented clusters. At the same time, CDC cuts off the noises and outliers. In the second phase, CDC employs the concept of K-means clustering algorithm to select a greater cluster to be the center. Then, the greater cluster merges some smaller clusters which satisfy some constraint rules.Due to the merged clusters around the center cluster, the clustering results show high accu racy. Moreover, CDC reduces the calculations and speeds up the clustering process. In this paper, the accuracy of CDC is evaluated and compared with those of K-means, hierarchical clustering, and the genetic clustering algorithm （GCA）proposed in 2004. Experimental results show that CDC has better performance.

浅析中国高技术产业的战略性贸易政策

政府的战略性贸易政策不仅对产业的国际竞争力有着十分重要的影响，而且对比较优势的动态发展有着深远的意义。面对世界各国在高技术产业日益激烈的竞争态势。中国有必要在高技术产业实施战略性贸易政策，从进口保护、出口补贴和相关国内政策三方面着手，通过科学安排各种政策措施，为我国高技术产业的发展创造良好的内外环境。     

《吾国吾民》与西方“中国形象”话语的互动

林语堂在《吾国与吾民》中建构的“中国形象”与西方“中国形象”话语谱系有着明显的联系与区别。针对西方“中国形象”话语的负面成分。例如“黄祸说“”以及中国妇女形象等问题，林语堂在建构自己的“中国形象”时作了修改；同时，林语堂也借鉴了西方“中国形象”的合理成分。这一借鉴隐含了现代性的观照。林语堂的“中国形象”建构策略为中西文化交流提供了很好的范倒。     

基于Push-Over方法的纯钢框架弹塑性分析

应用Push-Over方法的2种荷载形式,对一个纯钢框架结构体系在地震作用下的弹塑性性能进行了分析.通过对其变形性能和塑性铰规律的研究,得到纯钢框架体系的抗震性能,还通过对其塑性铰发生位置和发生顺序规律的研究,得出纯钢框架结构的薄弱层和最不利位置,为纯钢框架结构体系的优化设计提供了理论基础和前提条件,同时也有利于纯钢框架结构体系在抗震设防地区的推广.
