    序言

    近年来,我国的高等职业教育在国家政策的大力扶持下,得到了长足的发展,人才培养模式更加符合我国现阶段经济发展的需求,课程设置更加重视实用知识的传授和实践能力的培养。教育主管部门与时俱进,对高职高专的英语教学适时做出调整,提出“实用为主,工学结合”的指导原则,在日常的英语教学中加大了专业英语教学的比重,凸显了专业英语教学的重要性。
    《机械英语》正是为了满足广大高职高专院校开设专业英语课程的要求,遵循教育部高等教育司颁发的《高职高专教育英语课程教学基本要求》的指导原则而进行编写的。为了做好这项工作,我们除了遵循教育部规定的一般原则外,还特别注意到了如下几点:
    一、专业特色明显。本教材所选的材料与一般的机械科普读物不同,不是对于专业知识的简单罗列,而是对专业知识的梳理介绍,目的是提高学生的专业英语阅读能力,使其能够在今后的工作中自主地吸收国际同行的有益经验和知识。

    In the Periodic Table of Elements by a Russian chemist ,Dmitri Mendeleev,about half of the elements are metals.Metals are usually divided in totWO groups:ferrous and no nferrous.In contrast to ferrous,nonferrous metals do not containany iron.Copper,aluminum,chromium are some examples.
    From the standpoint of commerce,however,an absolutely pure metal has never appealed to engineers,such as pure iron,which is too soft for machine parts.And of all these metallic elements。only a few are suitable for the engineering purpose.Steel and cast iron are the most common metals in use An alloy is a mixture of one or more elements in a metallic matrixFor example,steels are alloys of iron and carbon by adding one or more small amounts of the following elements:nickel,chromium,manganese,silicon,tungsten and so on.
    Carbon is the most important element in steel.It determines the mechanical properties by the adding percentage of car bon.In this connection,low-carbon steels(1ess than 0.30%),with better forming properties.Are usually used for low-strength products.And medium-carbon steels(0.30%-0.60%)can meet the requirement of forgings.strength and ductility for mechanical parts or machines.
