Evolution is an intrinsic property of software, and the process of software evolution consists of a series of activities.

王炜，博士生，主研领域：软件工程，形式化方法，软件演化演化性是软件的固有属性。

Among these strategies, the first one is used to remove implementation code of irrelative functions according to users' requirements for software functions in particular scenarios, and the others are used to optimize software performance by removing redundant code and transforming code.

实现了在具体的应用场景下根据用户的功能需求而删除无关功能的实现代码，另外几种策略通过删除冗余代码和变换代码等现有的软件优化方法，减小软件的大小，提高代码的执行效率，实现软件性能的优化。

Biodiversity is one of the front areas of current biological research. The mechanisms of the formation, spatial distribution pattern, conservation and utilization of biodiversity have been an important area of biological and environmental research. In this study, through analyses of data about plant diversity, animal diversity, geographic factors, climatic factors, and energy factors by use of GIS software, statistic software and ecology software, the mainland of China was divided into 241 small districts of 2° by 2°. The environmental factors in each district were analyzed and isopleth maps of environmental elements were depicted.

生物多样性是当今生物学研究的热点问题之一，生物多样性的形成机制和分布格局以及保护利用问题一直是生物学和环境科学所研究的重要内容，本文由此出发，以中国陆地为研究区域，通过植物多样性数据、动物多样性数据、地理因子、气候因子、能量因子等资料，利用MAPGIS、MAPINFO等GIS软件，SPSS、DPS等统计学软件以及CANOCO等生态学软件，将中国陆地划分为241个小区，分析了各区内的环境特点，统计了各区内生物多样性的数量，并绘出环境因子等值线图，中国陆地种子植物科、属、种，裸子植物种、蕨类植物种、兽类、鸟类、爬行类、两栖类种数的等值线分布图，对中国陆地植物、动物多样性现状、分布格局及与环境因子的关系进行了研究。

Results the image data of spiral CT have been sent into PACS and recorded in CD-R At any moment the pictures of image data can be shown on terminal, can be applied to make teaching lantern slide by Power Point and to make multimedia teaching software by Authorware.

结果 ：运用FTP软件把工作站里制作好的彩色图像信息传入PC机并进入我院PACS系统进行光盘刻录，存储于光盘塔中，可随时用PACS系统中的任一PC机调出，用ACDSee32、Photoshop、Win98 映象等软件显示和打印彩色图象，用Powerpoint来制作教学幻灯片，用Authorware来制作多媒体教学软件。

The article introduces a method on software preventing copy Use particular disk tract juncture technology to make maternal disk action prevent copy disk of software confirm larcener software by installing hard disk parameter which has been encryped compared and storaged .

介绍采用特殊磁道接缝加密技术制作的母盘作为安装软件的防拷贝磁盘；采用硬盘安装参数经加密，保存，比较，判别确定是否为盗版软件，达到软件的防非法拷贝

This investigation shows further, in future in 5 years, about the software lieutenant general that the enterprise of the half buys has 50 or more software are software opening a source.

这个调查进一步显示，在未来五年里，大约一半的企业购买的软件中将有50或者更多的软件是开源软件。

Once more, applys three-dimensional CAD software Pro/Engineer establishing the geometry models of all kinds of parts in the crank link mechanism, then useing the Pro/E software assembling function assembles the components of crank link into the piston module, the connecting rod module and the crank module, then using Pro/E software mechanism analysis module (Pro/Mechanism), establishes the multi-rigid dynamics model of the crank link, and carries on the kinematics analysis and the dynamics analysis simulation, and it studies the piston and the connecting rod movement rule as well as crank link motion gear movement envelopment. The analysis of simulation results shows that those simulation results are meet to true working state of engine.

再次，应用三维CAD软件：Pro/Engineer建立了曲柄连杆机构各零部件的几何模型，在此工作的基础上，利用Pro/E软件的装配功能，将曲柄连杆机构的各组成零件装配成活塞组件、连杆组件和曲轴组件，然后利用Pro/E软件的机构分析模块(Pro/Mechanism)，建立曲柄连杆机构的多刚体动力学模型，进行运动学分析和动力学分析模拟，研究了在不考虑外力作用并使曲轴保持匀速转动的情况下，活塞和连杆的运动规律以及曲柄连杆机构的运动包络。

Here are some trouble in the design of electric industrial remote monitoring system, such as the rapid rising of software cost, high complexity, without a logic system for the product; the reason is: in the developing process, requirement is not clear; lack of methods and tools; the expanding of software scale; the enhance of complexity.

这主要是因为：在软件开发过程中，用户需求不明确；缺乏有力的方法学和工具方面的支持；随着软件应用范围的扩大，软件规模愈来愈大；其复杂性也在急剧地增加。

Support software is a series of software, which support development and maintenance of other software .

支撑软件是支撑其它软件的开发与维护的一系列软件。

It influences not only every phrase of the software design, but also maintenance and extend of the software system.

软件系统的结构设计是从计算机软件的角度对软件系统的观察分析，而不是用户角度。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
