a Part 1 Notes to text Data Compression 1)In com puter science and information theory, data com pression or source coding is the process of encoding information using fewer bits than an unencoded representation would use through use of specific encoding schemes.在计算机科学和信息理论中,数据压缩 或信源编码其实就是指采用比未经编码的信息表现方式更少的字节,通 过专门的编码系统进行编码的过程 注释:此句是主系表句型。 data compression or source coding 是主语, the process of encoding information是表语, using fewer bits和 through use of specific encoding schemes是修饰 encoding information的状语。 than an unencoded representation would use 是比较状语从句。 2)For exam ple, this article could be encoded with fewer bits if one were to accept the convention that the wordcompression"be encoded as"comp".例如,假如我们接受这样一种约定,也即是:将 compression"编译为"comp",那么用较少的位数就可以给这篇文章 完成编码。 注释: if one were to.是条件状语从句,were是虚拟语气,表示假设; that引导的从句是同位语,用以解释 convention的具体内容。 2021/2/20 P22021/2/20 P.2 @ Part 1 Notes to Text 1) In computer science and information theory, data compression or source coding is the process of encoding information using fewer bits than an unencoded representation would use through use of specific encoding schemes. 在计算机科学和信息理论中，数据压缩 或信源编码其实就是指采用比未经编码的信息表现方式更少的字节，通 过专门的编码系统进行编码的过程。 注释：此句是主系表句型。data compression or source coding 是主语， the process of encoding information是表语，using fewer bits和 through use of specific encoding schemes是修饰encoding information的状语。than an unencoded representation would use 是比较状语从句。 2)For example, this article could be encoded with fewer bits if one were to accept the convention that the word "compression" be encoded as "comp".例如，假如我们接受这样一种约定，也即是：将 "compression"编译为 "comp"，那么用较少的位数就可以给这篇文章 完成编码。 注释：if one were to…是条件状语从句，were是虚拟语气，表示假设； that引导的从句是同位语，用以解释convention的具体内容。 Data Compression
