A comparative Study of novels written by American Writer Jack London and Chinese Writer Jiang Rong

The Call of the Wild has been the most widely read American novel in the world,while the Wolf Totem has made a hit since its publication. This paper attempts to conduct text analysis on these two works about wolves from the perspective of Ecocriticism and make a parallel study between them according to the theory of Comparative Literature. By comparison, this thesis aims to find the similar and different points between the two works, trying to find a more reasonable answer to the question of human’s relation with the nature.     

并联机床虚拟样机建模与加工过程动力学仿真

为了实现并联机床性能的真实预测,确保加工过程的安全性,提出了基于Adams的并联机床加工过程的动力学仿真方法。在包括螺旋副在内的仿真模型的各个运动关节加载了摩擦力,实现了仿真模型与实际机床的高度仿真;根据NC文件和切削参数,建立并联机床加工过程的切削力模型和运动控制模型,实现了机床加工零件全过程的动力学仿真。对5-UPS/PRPU并联机床的加工过程进行了仿真分析,仿真结果准确的预测了实际加工中可能出现的问题。该方法简单、准确、可靠、实用性强。     

略论魏晋六朝骈文的兴盛与文学自觉的关系

骈文兴盛于魏晋六朝,不是偶然的文学现象,其时正值中国文学进入自觉的时代。骈文充分地展现了文学作为语言艺术的本质,故而随着人们对文学认识的日益深化,文坛骈风大开,进入一个骈俪化的时代,在句式的整练、声韵的和谐、辞藻的雕饰诸方面体现了文学艺术的自觉追求。     

A Scalable Data-Distributed Algorithm for Volume Rendering on Parallel Virtual Machines

IntroductionVolume rendering is an essential method forexploring the inner structure of complex3- D data.One of the classic volume- rendering approaches isthe so- called ray- casting algorithm. In thisalgorithm,each image pixel is rendered accordingto a ray which is emitted from the pixel and isoriented towards the observation direction. Thecomputations along each ray consist of two typicalphases:resampling of the3- D data followed by thecolor composition. Unfortunately,both phases aretime c…     

矿井通风困难时期通风优化方案研究

针对陕煤澄合矿业有限公司二矿分公司矿井三水平延伸工程遇到的通风系统通风困难时期状况,文中在分析了矿井通风阻力分布特征和主要通风机性能特性的基础上,结合矿井三水平延伸工程即将完成主皮带斜井工程的情况,提出改善通风系统困难状况的2种方案,一是在东、西风井安装主通风机,进行双风机并联通风,二是利用主皮带斜井为回风井,其余井筒做进风井通风.经过分析发现,采用双风机并联通风存在有通风网络公共风路风阻大小与待选通风机风压之间存在相关性关系,澄合二矿风机并联工作不满足这一关系.经过通风网络解算,验证得出主皮带斜井回风可以改善通风系统困难状况,从而确定了这一较好方案,现场工程验证了所选择通风方案能够满足矿井安全生产要求.     

运用现代汉语规律突破文言文学习难点

文言文与现代汉语差异极大,如何有效提高文言文的学习水平是困扰众多文言文学习者的一大难题,但以文言文与现代汉语的联系为落脚点和出发点,借助现代汉语语法分析并掌握文言文学习中的两大难点却是行之有效的方法。     

PR格式的时间并行算法及其数值实验

二维抛物型方程的传统并行算法只是在空间层上是并行的,在时间层上是步进的.本文将PR格式改造为一类恰是在时间层上是并行的,在空间层上是步进的.该格式绝对稳定,局部截断误差为O( k2-2+h2).文中的数值实验报告验证了理论分析的正确性.     

2010年《政府工作报告》的文体学特征及英译

对2010年《政府工作报告》的词汇和句法进行个案研究,探讨在《政府工作报告》的英译过程中,为让译入语读者全面、客观、公正地理解原语文献中的政治观点,译者必须作出词汇和句法的变通,以使译文既符合译入语的行文习惯,同时又不丧失原语特殊词汇和句法所传达的意义,充分做到有机结合。     

Dynamic domain decomposition method and its application on nonlinear problem

In this paper,domain decomposition method(DDM) for numerical solutions of mathematical physics equations is improved into dynamic domain decomposition method(DDDM) . The main feature of the DDDM is that the number,shape and volume of the sub-domains are all flexibly changeable during the iterations,so it suits well to be implemented on a reconfigurable parallel computing system. Convergence analysis of the DDDM is given,while an application approach to a weak nonlinear elliptic boundary value problem and a ...
