Features of the Formation of Multi-view Autostereoscopic Image without Vertical Parallax

1.Introduction The reproduction systems of 3D images without using eyeglasses and other special accessories has always attracted attention and aroused great interest of developers and consumers of such equipment because of totally accurate image and method of its presentation.Such systems can be used and are already partially used in advertising,television,different devices (i.e.smartphones,tablet computers),at the exhibitions,etc.,as well as in various technical applications,training systems,simulators,etc.     

Study on effect of segments erection tolerance and wedge-shaped segment on segment ring in shield tunnel

INTRODUCTION Shield tunnel method has become the most pre- ferred method in city tunnel construction because of its excellent attributes: little effect on surrounding environment, fast and safe construction, outstanding performance in earthquake resistance, etc. (Zhang et al., 2004). In different shield tunnels, the arrangement and number of segments are different, but the whole assembling process is generally the same. The as- sembling process begins with A2P, then A1P, A3P, BP, CP, …     

单片机测控系统中P3口的双重使用

MCS－51系列单片机的P3口是一个双功能口，具有特殊性。当T0口（P3．4）或T1口（P3．5）作为内部定时器使用时，其口线还可作为通用输入／输出口使用。章对单片机P3口的定时器／计时器口的双重使用方法，从原理上作了详细分析，并介绍了其在真空压强、测量仪中的实际应用。解决了单片机自身口资源有限的矛盾。

中西诗画论之文化基因比较

本比较了中西诗画论的异同，认为中国诗画论的主导倾向是诗画同源论，西方诗画论的主导倾向是诗画异质论；本从中西哲学观念和思维方法、中西各自的诗画传统、中西诗画论产生的化背景等三个方面，说明了其成因；总结了中西诗画论各自的意义与局限。     

ACE基因多态性与有氧耐力运动关系研究

目前普遍认为ACE(血管紧张素转换酶)的水平和心血管的形态、功能密切相关。ACE基因的多态性是人耐力素质优劣的决定性因素之一。为了解运动员血管紧张素转换酶(ACE)基因插入或缺失(I/D）多态性情况，探讨ACE基因多态性与有氧耐力可能的关系，用聚合酶链反应(PCR)技术检测20例运动员和20例健康对照者的ACE基因多态性。结果位于ACE基因16内含子的L／D多态性经PCR扩增后呈三种基因型：纯合子插入型(II）、纯合子缺失型(DD)和杂合子插入或缺失型(ID)。耐力运动员组Ⅱ基因型和Ⅰ等位基因频率显著高于健康对照组。结果表明ACE基因可能在运动员的有氧耐力中起重要作用。

富氧条件下CuO/TiZrO4催化还原NO的研究

用共沉淀法制备TiZrO4复合氧化物，并作为载体。采用等体积浸渍法担载CuO制成CuO／TiZrO。催化剂，考察其在富氧条件下以CH4作还原剂催化还原NO的性能，研究了CuO负载量、反应温度对NO转化率的影响。结果表明CuO负载量为20％时催化活性最好，反应温度为200℃时，NO转化率可达65％。     

More Powerful Tests of Simple Interaction Contrasts in the Two-Way Factorial Design

For the two-way factorial design in analysis of variance, the current article explicates and compares three methods for controlling the Type I error rate for all possible simple interaction contrasts following a statistically significant interaction, including a proposed modification to the Bonferroni procedure that increases the power of statistical tests for deconstructing interaction effects when they are of primary substantive interest. Results indicate the general superiority of the modified Bonferroni procedure over Scheffé and Roy-type procedures, where the Bonferroni and Scheffé procedures have been modified to accommodate the logical implications of a false omnibus interaction null hypothesis. An applied example is provided and considerations for applied researchers are offered.
