High-extensible scene graph framework based on component techniques

INTRODUCTION With the tremendous growth of the digital en- tertainment industry in the past decades, the scale of game scene is becoming more gigantic. To effectively manage and organize the massive data, game engine usually uses hierarchical scene graph. Many popular 3D modelling tools, such as Maya, 3D Studio Max, use scene graph to manage the scene content (Sowizral, 2000). 3D modelling software—Houdini directly edits scene graph to create and modify the virtual environment. Most v…     

人格发展的稳定性与可变性

长期以来,人格的稳定性与可变性是心理学中一个富有争议的主题。文章从人格发展稳定性与可变性的内涵、机制、相互关系等方面的理论和研究进行了探讨,并对未来研究方向提出若干看法。     

TiNx-SiO2减反射膜的制备

This paper describes the preparation and properties of TiNx-SiO2 double-layered antireflective(AR) coatings that were applied with print process. The coating material was analyzed and TiNx was used instead of TiO2 as high refractive material. The influence of solution concentration on AR property was studied. The testing result shows that the coatings using print process are featured with excellent mechanical property and the AR property is comparable to American Southwall AR product. It is expected that the study would promote the industrialization progress in AR coatings.     

高职院校人事分配制度改革的实践与研究

在高等教育大众化进程中，高职院校赢得了发展的新机遇，但高职院校现有的办学力量不强，师资结构不尽合理。因此，高职院校内部人事分配制度的改革已成为备受关注的实践性课题。在这改革中，把握形势、深入剖析、明确改革与发展的关系是前提。定编定岗、全员聘任、建立科学用人机制是关键，效率优先、兼顾公平、强化科学分配机制是核心。     

Application of derivative ratio spectrophotometry for determination of β-carotene and astaxanthin from Phaffia rhodozyma extract

INTRODUCTION Carotenoids are a class of natural fat-solublepigments generally found in plants, algae, and pho-tosynthetic bacteria, where they play a critical role inthe photosynthetic process. Carotenoids also exist insome non-photo-synthetic bacteria, yeasts, and moldswhere they may carry out a protective functionagainst damages by light and oxygen. Although ani-mals can not synthesize carotenoids within theirbodies, they can intake carotenoids from their dietsleading to bright meat col…     

社会组织在城市少数民族流动人口嵌入式社区构建中的作用

人口大范围流动给城市民族工作带来新的问题与挑战。社会组织用一种组织化的方式将民族流动人口纳入到服务管理体系中。社会组织能够在增强民族流动人口社会融入、扩展社会资本、重构社会关系网络等多方面架起少数民族流动人口与政府沟通的桥梁。社会组织介入民族流动人口服务与管理是做好新时期城市民族工作的有益探索,是构建城市少数民族嵌入式社区环境的重要方式。

DNA: From Carrier of Genetic Information to Polymeric Materials

Research has shown that the DNA molecule can not only store genetic information but also serve as a polymeric biomolecule for the fabrication of functional materials. The unique precise molecular recognition capability and sequence programmability, combined with its good biocompatibility and biodegradability, impart the DNA molecule considerable potential for use in the construction of multifunctional materials. Depending on the composition, DNA-based materials have been generally categorized into pure DNA materials that are entirely composed of DNA and hybrid DNA materials that are composed of DNA and other functional compositions. Recently, we have developed a series of DNA-based materials that can be applied in diagnosis and therapy, and this review summarizes the relative work. Although challenges still exist regarding the real applications of DNA-based materials such as the high cost of DNA, the difficulty in scale-up, and the low resistance to nuclease, we believe that these drawbacks will be overcome with the development of technology, and new opportunities will emerge in the field of diagnosis and treatment.     

从新诗编选的四次高潮看百年新诗观念的历史变迁

中国现代新诗的百年编选历程出现过四次高潮,都具有自身的时代特色并与中国现代诗学的变迁紧密相连:20世纪初的编选属于开创期,是对文学革命的宣传、捍卫和初步总结;50年代则是在国家意志的支配下,对新文学传统的重新定位;90年代则是在美学热、回归文学本位的背景下,总结20世纪中国文学而对新诗进行的梳理;21世纪以来的编选则更加多元,也更富有深度,是对百年新诗的系统总结,在美学标准与历史标准间把握好尺度,是当今新诗编选面临的普遍问题.
