英语翻译
Software development is concerned with creating computer programs that perform efficiently.In developing computer software,computer scientists and engineers study various areas and techniques of software design,such as the best types of programming languages and algorithms to use in specific programs,how to efficiently store and retrieve information,and the computational limits of certain software-computer combinations.Software designers must consider many factors when developing a program.Often,program performance in one area must be sacrificed for the sake of the general performance of the software.For instance,since computers have only a limited amount of memory,software designers must limit the number of features they include in a program so that it will not require more memory than the system it is designed for can supply.
Software engineering is an area of software development in which computer scientists and engineers study methods and tools that facilitate the efficient development of correct,reliable,and robust computer programs.Software engineers develop software tools and collections of tools called programming environments to improve the development process.For example,tools can help to manage the many components of a large program that is being written by a team of programmers.

软件开发在于开发出有效运行的计算机程序.在开发计算机软件时,计算机科学家和工程师研究多种领域和技术的软件设计,如把最好的编程语言和算法用在某一特定项目上,以及用来研究如何有效储存和找回信息,解开某些软件（计算机组合）的计算限制.软件设计者在开发一个项目时必须考虑到很多因素.通常,程序在一个方面的表现必须要为软件的整体性能做出牺牲.比如说,既然计算机之只有有限的存储量,软件设计者必须限制放入程序的功能的数量,那么程序才不会要求超出系统可以提供的存储.
软件工程是软件开发的一个方面,其中,计算机科学家和工程师研究让有效开发正确、可靠、强健的计算机程序变得更为容易的方法和工具.软件工程师开发软件工具和叫做编程环境的工具集合来改善编程的进展.比如说,可以用来成功管理由一个编程团队写成的大型程序的很多组件的工具.
