后殖民文学话语特征

本文通过对后殖民文学中本土作家、移民作家及殖民地白人移民后裔作家写作话语特征的分析，系统地阐述了后殖民文学的话语共通点：历史的重写、身份的重塑和语言的混杂。     

通用开放式绘图仪接口软件设计与实现

本文针对TANGO软件所支持的图形输出设备中不包括CALCOMP系列绘图仪的问题,设计了TANGO图形文件与CALCOMP系列绘图的接口软件.由此阐述了一种通用图形描述语言及开放式绘图仪接口软件的设计思想与技术实现.     

凸轮运动参数设计

根据被驱动件在两个运动范围内的速度不得小于1.84m/s这一要求,设计了一个凸轮。因考虑到二阶可导,故采用3次样条插值法。使用软件MATLAB6.5进行计算,并绘出凸轮行程、速度、加速度随时间的变化曲线。经验证,该凸轮满足设计要求。

论信息时代网络语言中的外来语

随着信息时代网络交流的日益普及,网络与语言结合,形成了一种全新的语言模式—网络语言。网络语言中一个突出的现象是大量外来语杂糅其中。通过分析网络语言中外来语的表现形式,探讨网络语言中外来语流行的原因,并提出如何正确看待这一现象。     

契诃夫短篇小说的“简单”特色

契诃夫是俄国十分著名的小说名匠,它的短篇小说别具特色,在语言运用方面,精炼、直白不冗杂,给人一种清淅明了的舒畅;在人物塑造方面,他运用简单的线条、笔触来勾勒,能够直击人物的重点;在叙事角度,他选择用日常生活中的小事来阐述大的哲学道理;契诃夫的短篇小说,虽简单却五脏俱全,细节描写细致入微,耐人寻味。下面文章将分就契诃夫短篇小说中的"简单"特色进行具体阐述。     

内蒙古贺兰山马鹿的种群数量及种群结构

为了掌握内蒙古贺兰山国家级自然保护区内马鹿(Cervus elaphus)的种群数量和种群结构,维护内蒙古贺兰山的生态平衡。于2017年11—12月,2018年4—6月、11—12月,2019年4—6月,在内蒙古贺兰山国家级自然保护区内,利用样线法对保护区内的马鹿进行调查,采用Distance R进行数据分析,估测种群数量和种群密度,并对种群结构进行探讨。研究发现,马鹿在2018年冬季种群数量最高约为2452(1678—3578)只,种群密度为3.705(2.539—5.048)只/km²,遇见率为1.943只/km。遇见率年际间变化不明显(F=0.12,P=0.986);混合群出现的次数最高,雄性群出现的次数最低,不同集群类型在不同季节的差异极显著(P<0.001);群大小在不同季节的差异不显著(P=0.132);雌雄比在不同季节中没有太大变化。     

ON THE INTERFACE BETWEEN AUTOCAD AND THE ADVANCED LANGUAGE

This paper comprehensively discusses the interface between AutoCAD and the advanced language. It presents three main ways: by means of . DXF file, SCR file and AutoLISP language. The former two have been used by some people in China. This paper presents the method with its programs for its accomplishment. As to the last one, the author has developed its application with the method for its accomplishment, the problem and the handling method for deletion of library function. AutoCAD can be used as support software for microcomputer CAD. This paper provides some references for technical personnel concerned. The programs in this paper have been all verified by IBM PC/XT, GWO520-CH. The pictures are drawn by DMP-56A.     

Vibration Analysis and System Simulation for a Stalled Wind Turbine

The aerodynamic characteristic of wind turbine is calculated by applying the Blade Element Momentum(BEM) theory.Also finite element mode analysis is done for the tower and the rotor.Then the multi-dynamic model of the wind turbine is built in Adams.Also the drive chain is calculated by applying state space method and programmed in Matlab/ Simulink.With that the combined simulation of vibration characteristics is carried out on the base of MATLAB/Simulink and ADAMS,in which the transmission effects and aero-elasticity coupling is fully considered.The results show that the method is able to simulate the vibration characteristic almost the same as software Bladed,which is well-known for analyzing performance and loads for the design and certification of wind turbines.
