The Design and Implementation of an Object- Oriented Data Report System Based on J2EE Platform
基于J2EE的面向对象型数据的报表系统的设计与实现

Feng Li,Li WenSheng,<br>冯莉,文生
计算机系统应用 , 2006,
Abstract: 本文描述的是一个在线考试中的报表系统的研发过程,从开发工具的选择到利弊的分析,再到根据开发平台、整个考试系统的架构设计以及所选的报表开发工具来研究并最终开发出满足需求的报表系统。在项目开发的过程中主要体会到了将传统的关系型数据库通过OR映射工具转化为持久对象,从而以对象的形式来操作数据库数据的创新性设计思想,并且切实的体会到了两种方式的利弊。

Abstract: 概述在语音分析研究工作中,把声音信号分为一段段地来进行考察是很重要的一种手段。例如从“好”(hao)这个音节中把h,a,o各个音素,以及它们之间的过渡成分分别孤立出来,以便研究它们的特性和相互间的关

浅论《金匮》肾虚酸削证之辨治
文生
中国中医药信息杂志 , 1999,
Abstract: 酸削一证,出自《金匮?血痹虚劳篇》。原书虽没将它作为一个独立的疾病来论述,但由于本证具有在肾虚基础上产生疼痛、行走困难等较为固定的一组症状和因虚致瘀、因瘀致病的病因病机,在临床中广泛出现,并易与症状相似病机却截然不同的中风后遗症、痹证、痿证等混淆在一起,而且也不同于一般的虚损证。因此,笔者认为有必要使用“肾虚酸削证”这一命名来加以区别。临床上常见的腰肌劳损、早期股骨头坏死、腰椎骨质增生症、膝关节骨质增生症、跟骨骨刺等顽疾均可纳入本证辨治范围,兹举病例说明。
Comparative Study of Developmental Trends of Domestic and Foreign Chinese Medicine Research & Development
中药研发国内外发展趋势的比较研究

Abstract: The status quo of traditional Chinese medicine research and development (TCM R&D) both at home and abroad is analyzed from the eastern and western views, in order to present some rational suggestions for mastering the direction of TCM R&D in China. The historical review on references, expert consulting and field survey are adopted based on such background as TCM resources, industrial status, product structure, market economy and medical demand, especially focusing on Japan, German, USA and EU. The results are summarized as follows: 1. Evolution in connotation and denotation of TCM; 2. TCM R&D in China in three aspects:, TCM R&D focusing on tradition under the guidance of TCM theories; TCM R&D initiated by the notion of natural botanical drugs; TCM R&D in the direction of integrating TCM and natural botanical drugs; 3. R&D trends of botanical drugs overseas and TCM in China, which show convergence in the reversal feature: neighboring countries benefit from TCM;
Optical transition of the charged excitons in InAs single quantum dots
电场调谐InAs量子点荷电激子光学跃迁

物理学报 , 2013,
Abstract: Quantum dot (QD) samples studied in the experiment are grown by molecular-beam epitaxy on semi-insulating GaAs substrates. The photoluminescences (PLs) of the excitons in a single QD are measured at 5 K. The PL spectra of the excitons, biexcitons and charged excitons are identified by measuring and analyzing both PL peaks of the circular and linear polarization and power-dependent PL properties. The charged exciton emissions can be tuned by applying a bias voltage, i.e., negatively charged excitons are changed into positively charged excitons by changing the voltage from 1.0 to -1.0 V. It is shown that the electron-spin will slowly relax compared with that of the hole when they relax from wetting layer into the QD.

第四纪研究 , 2007,
Abstract: 通过对呼包盆地钻孔岩芯进行系统的岩石学、年代学和孢粉带的分析,综合盆地已有的研究成果,并与邻区对比,划分了盆地第四纪地层单位,同时探讨了河套古湖泊在第四纪的演化特征.结果为:1)剖面存在两个假整合接触面(Q1/Q2和Q2/Q3),可划分为4个沉积旋回,7个孢粉带.2)剖面第四纪地层从下至上依次可划分下更新统(1070±150~844±126kaB.P.)、中更新统沟子板组(520±78~271±40kaB.P.)、上更新统萨拉乌苏组和城川组(108.7±7.8~14.80±1.03kaB.P.),以及全新统.3)河套盆地在第四纪存在4个古湖泊发育时期,即早更新世(80.0~107.0万年或更早),湖盆处于强氧化环境;中更新世早期(43.0~45.1万年),湖盆氧化强度降低;中更新世晚期(19.2~38.5万年),湖盆处于强烈的还原环境;晚更新世(2.4~11.3万年),湖盆处于还原环境.其间隔期为湖泊消亡或大规模萎缩时期,意味着盆地停止下降甚至处于上升隆起的剥蚀状态.
Warped DCT image compression based on evolutionary algorithm
基于演化算法的卷曲DCT图像压缩

中国图象图形学报 , 2013,
Abstract: In the process of image compression, the discrete cosine transform (DCT)makes the image blurry. With the frequency warping, the warped discrete cosine transform (WDCT)overcomes this shortcoming. However, it is difficult for traditional algorithms to select the frequency warping parameters. Therefore, in this paper, we present a new WDCT image compression algorithm based on an evolutionary algorithm (EAWDCT)to select the parameters with the global optimization of the evolutionary algorithm. To improve the convergence speed and to gain the best parameters quickly and accurately, a heuristic method is used to design the chromosome coding methods and evolutionary operators according to the parameters characteristics. The experiments show that the new algorithm (EAWDCT)improves the peak signal to noise ratio and signal to noise ratio while reducing the root-mean-square error effectively.
