1 Unit 10 What Is Chemical Engineering?
什么是化学工程学
In a wider sense, engineering may be defined as a scientific presentation of the techniques and facilities
used in a particular industry. For example, mechanical engineering refers to the techniques and facilities
employed to make machines. It is predominantly based on mechanical forces which are used to change the
appearance and/or physical properties of the materials being worked, while their chemical properties are left
unchanged. Chemical engineering encompasses the chemical processing of raw materials, based on chemical
and physico-chemical phenomena of high complexity.广义来讲，工程学可以定义为对某种工业所用技术和设备的科学表达。例如，机械工程学涉及的是制造机器的工业所用技术和设备。它优先讨论的是机械力，这种作用力可以改变所加工对象的外表或物理性质而不改变其化学性质。化学工程学包括原材料的化学过程，以更为复杂的化学和物理化学现象为基础。Thus, chemical engineering is that
branch of engineering which is concerned with the study of the design, manufacture, and

常见分子式及化学反应式的读法
字母部分均按字母名称读出；化学反应式中的符号→，读作yields 或forms，意即生成：
A) H2O, [eitʃ] [tu:] [əu]
B) C6H12O6 → 2C2H5OH + 2CO2
C six H twelve O six yields two C two H five O H plus two C O two.
C) NaOH → Na++ OH-
N sub a O H yields N sub a positive plus O H negative.
D) 1、Nitrogen reacts with hydrogen to form ammonia at high temperature and pressure with the presence of a catalyst. 2、1 mol nitrogen reacts with 3 mol hydrogen to form 2 mol ammonia at high temperature and pressure with the presence of a catalyst. 3、 Nitrogen combines with hydrogen to form ammonia at high temperature and pressure with the presence of a catalyst. 4、Reaction between nitrogen and hydrogen at high temperature and pressure with the presence of a catalyst gives ammonia. 5、At high temperature and pressure, reaction of nitrogen with hydrogen in the presence of a catalyst takes place. E) Zinc treated with hydrochloric acid forms hydrogen and zinc chloride.
