本门专业英语课程是指适合大学动物医学专业学生,介绍和讲解有关动物医学方面的 特别英语。其基本内容是与动物医学专业有关基础课、专业基础课和专业课的英文文章 涉及解剖学、组织胚胎学、动物生物化学、动物生理学、兽医产科学和繁殖学、兽医传染 病学和免疫学。同时本门课程也重点讲述英文摘要的翻译以及如何将中文摘要翻译成英 文。本门课的主要学习目的是了解动物医学的概念,知识和内容的英文表达,提高专业英 语水平:掌握中文摘要翻译成英文的技巧

Introduction Ideally, the system parameters along with the signal variables have infinite precision taking any value between -oo and · In practice, they can take only discrete values within a specified range since the registers of the digital machine where they are stored are of finite length

2.1 Discrete-Time Signals: Time-Domain Representation Signals represented as sequences of numbers, called samples Sample value of a typical signal or sequence denoted as x[n] with n being an integer in the range-oo≤n≤∞ x[n] defined only for integer values of n and undefined for noninteger values of n Discrete-time signal represented by {x[n]}

Objective-Determination- of realizable transfer function G() approximating a given frequency response specification is an important step in the development of a digital filter If an IIR filter is desired, G() should be a stable real rational function Digital filter design is the process of deriving the transfer function G

3.1 Discrete-Time Fourier Transform Definition- The discrete-time Fourier transform (DTFT) X(eio) of a sequence x[n] is given by jae In general,() is a complex function of the real variable and can be written as X(eio) Xre(eio) +j Xim(eio)

我从2002年7月开始翻译这本书,当时还是第二版。但是翻完前言和介绍部分 后, chinapub就登出广告,说要出版侯捷的译本。于是我中止了翻译,等着侯 先生的作品。 我是第一时间买的这本书,但是我失望了。比起第一版,我终于能看懂这本书 了,但是相比我的预期,它还是差一点。所以当 Bruce eckel在他的网站上公开 本书的第三版的时候,我决定把它翻译出来

Java的基本哲学是“糟糕的代码根本就得不到执行”。 捕捉错误的最佳时机应该是在编译的时候,也就是程序能运行之前。但 是,不是所有的错误都能在编译的时候被发现。有些问题只能到程序运行 的时候才能得到处理。它们要通过某种方式,让引发问题的代码将适当的 信息传给那些知道该怎样正确处理这些问题的程序

多态性是继数据抽象和继承之后的,面向对象的编程语言的第三个基本特 性。 它提供了另一个层面的接口与实现的分离,也就是说把做什么和怎么做分 开来。多态性不但能改善代码的结构,提高其可读性,而且能让你创建可 扩展的(extensible)程序。所谓“可扩展”是指,程序不仅在项目最初的 开发阶段能“成长”,而且还可以在需要添加新特性的时候“成长
