A Fascinating Journey to the Old Town of Yuzhou     

Yang Kan 《中外文化交流(英文版)》2006,(7):24-26

Yuxian County, called Yuzhou in ancient times, enjoys unique terrains and old traditions. As it borders with the northern province of Shanxi, it shares many cultural and business similarities with Pingyao, an old town of Shanxi inscribed in the World Heritage List. Since it is not far from Beijing, Yuxian has become a frequent destination for travelers from Beijing. The Extraordinary Art of Paper Cut In a paper cut workshop of Yuxian County, I was fortunate to see the whole production …  相似文献

Zhang Jinqiu, a celebrated woman architect in contemporary China, is known for her successful designs blending tradition and modernity. With a large number of modern creations featuring distinctive traditional styles designed for the ancient city of Xi＇an as well as many other historical cities in China, Zhang has contributed to diversity of urban planning concepts and made valuable explorations on cultural dimensions of architectural design.  相似文献   

给远山织一片阳光     

陈宇 《全国优秀作文选(高中)》1995,(Z1)

走了将近一个小时的山路,我终于到了那个属全省最贫穷地区之一的小镇,火柴盒一般的房子拥簇在大山的阴影中,一样的破烂不堪,一样的阴暗潮湿。成群的孩子拖着长鼻涕、脏裤管在狭窄的小巷中穿梭嘻笑,这些八九岁的小男孩应该在美丽的校园生活,在宁静的教室就读,可是,眼前的这  相似文献   

History Museum of Shaanxi： A Treasure House of Ancient Art     

Shen Qinyan Yang Chaoying 《中外文化交流(英文版)》2006,(8):40-43

The History Museum of Shaanxi stands in the southern suburb of Xi＇an, capital city of Shaanxi Province, with the Big Goose Pagoda on its east side and the Da Xingshan （Great Benevolence） Temple on its west side. The neighborhood is the most dynamic cultural center in the Tang Dynasty （618 - 907 AD） where candidate scholars passing imperial examinations had their names inscribed on the Goose Pagoda as honors, emperors bestowed banquets to officials and honored scholars, noblemen appreciated dances and operas and poets ascended the Goose Pagoda to recite their poems on the Double Ninth Festival （the festival for climbing heights）. While numerous beautiful legends occurred in the neighborhood in the past, it attracts tourists from home and abroad with its unique charms today.  相似文献   

AC-dielectrophoretic characterization and separation of submicron and micron particles using sidewall AgPDMS electrodes     

Lewpiriyawong N  Yang C 《Biomicrofluidics》2012,6(1):12807-128079

The recent development of microfluidic “lab on a chip” devices requires the need to continuously separate submicron particles. Here, we present a PDMS microfluidic device with sidewall conducting PDMS (AgPDMS) composite electrodes capable of separating submicron particles in hydrodynamic flow. In particular, the device can service dual functions. First, the AgPDMS composite electrodes embedded in a sidewall of the device channel allow for performing AC-dielectrophoretic (DEP) characterization through direct microscopic observation of particle behavior. Characterization experiments are carried out for numerous parameters including particle size, medium conductivity, and AC field frequency to reveal important dielectrophoresis DEP information in terms of the crossover frequency and positive/negative DEP behavior under specific frequencies. Second, the device offers an advantage that sidewall AgPDMS composite electrodes can produce strong DEP effects throughout the entire channel height, and thus the robustness of the on-chip particle separation is demonstrated for continuous separation in a flowing mixture of 0.5 and 5 μm particles with 100% separation efficiency.  相似文献   

Gravity-oriented microfluidic device for uniform and massive cell spheroid formation     

Lee K  Kim C  Young Yang J  Lee H  Ahn B  Xu L  Yoon Kang J  Oh KW 《Biomicrofluidics》2012,6(1):14114-141147

We propose a simple method for forming massive and uniform three-dimensional (3-D) cell spheroids in a multi-level structured microfluidic device by gravitational force. The concept of orienting the device vertically has allowed spheroid formation, long-term perfusion, and retrieval of the cultured spheroids by user-friendly standard pipetting. We have successfully formed, perfused, and retrieved uniform, size-controllable, well-conditioned spheroids of human embryonic kidney 293 cells (HEK 293) in the gravity-oriented microfluidic device. We expect the proposed method will be a useful tool to study in-vitro 3-D cell models for the proliferation, differentiation, and metabolism of embryoid bodies or tumours.  相似文献   

杰出青年科学基金项目实施情况的若干思考     

陈宇  何杰  潘庆 《科技管理研究》2012,32(2):139-141

国家杰出青年科学基金项目的设立,体现了国家资助基础研究方式从以资助项目为主的单一模式到资助项目、资助带头人、资助团队的多元模式转变。实施十五年来,它在促进青年科技人才成长,加速我国高层次人才队伍建设,培养和造就一批冲击世界科技前沿的优秀学术带头人等方面起到了十分重要的作用。但是在评审机制和如何兼顾不同学科之间的均衡发展等问题仍需要不断地改进。  相似文献

讨论出真知     

杨斯毅Sim  Yang 《海外英语》2010,(11):54-55

在“冲击波英语”的理念中,听说在同一环境下同时受训的效果是最好的,单纯练习听力或者口语的效率都是事倍功半的。只听不说,就无法把知识转化成语言,常常使传统教学模式下的学生有话说不出;光说不听则无法在交际的互动过程中根据对方的语义说出对应和恰当的内容。  相似文献   

相变诱导塑性钢生产现状与发展趋势   总被引：2，自引：0，他引：2  

刘永前  陈宇 《武汉工程职业技术学院学报》2010,22(3):23-26

通过相变诱导塑性(transformation induced plasticity,TRIP)效应使钢板中残余奥氏体在塑性变形作用下发生马氏体相变,TRIP钢以其高强度、优异的成形性能成为近年来汽车用钢研究的热点。概述了相变诱导塑性(TRIP)钢的理论研究现状,讨论了其化学成分、微观组织形态、残余奥氏体含量等因素对材料性能的影响。介绍了国内外TRIP钢工业应用情况,并对TRIP钢的发展趋势做了展望。  相似文献
