在购买我的第一部CD唱机时,我能够解读推销标记上面的大多数技术语言。但是有一个标示却让我颇为迷惑,于是我叫过销售商,问道:"'混合脉冲D/A变换器'是什么意思?" "That means," she said, "that this machine will read the digital information that is encoded on CDs and convert it into an audio signal - that is, into music." " 它的意思是,"她说,"这个机器能够读CD碟上加码的数字信息,将它转换成声音信息-也就是说,转换成音乐。" "In other words this CD player plays CDs." " 换句话说,这个CD唱机能够播放CD碟。" "Exactly." " 正是如此。"
