1.Origins of the Chemical Industry

Although the use of chemicals dates back to the ancient civilizations, the evolution of what we know as the modern chemical industry started much more recently. It may be considered to have begun during the Industrial Revolution, about 1800, and developed to provide chemicals roe use by other industries. Examples are alkali for soapmaking, bleaching powder for cotton, and silica and sodium carbonate for glassmaking. It will be noted that these are all in

Elements and Compounds

元素与化合物

Elements are pure substances that can not be decomposed(分解) into simpler substances by ordinary chemical changes. At present there are 109 known elements. Some common elements that are familiar to you are carbon, oxygen, aluminum, iron, copper, nitrogen, and gold. The elements are the building blocks of matter just as the numerals 0 through 9 are the building blocks for numbers. To the best of1 our knowledge, the elements that have been found on the earth also comprise(包含) the entire universe.

2． 燃烧炉的内层为460mm厚的耐火砖,外层为230mm厚的绝缘砖。若炉的内表面温度t1为1400℃,外表面温度t3为100℃。试求导热的热通量及两砖间的界面温度。设两层砖接触良好,已知耐火砖的导热系数为?1?0.9?0.0007t,绝缘砖的导

t。两式中t可分别热系数为?2?0.3?0.0003取为各层材料的平均温度,单位为℃,λ单位为W/(m·℃)。

解：设两砖之间的界面温度为t2，由

t1?t2t2?t3?b1b2，得

q?t1?t2?1400?949?0.40/0.97?0.0007???2???1689W/m2

4．蒸汽管道外包扎有两层导热系数不同而厚度相同的绝热层,设外层的平均直径为内层的两倍。其导热系数也为内层的两倍。若将二层材料互换位置,假定其他条件不变,试问每米管长的热损失将改变多少?说明在本题情况下,哪一种材料包扎在内层较为适合?

解：设外层的平均直径为dm2，内层平均直径为dm1，则dm2?2dm1且??2?。 由导热效率方程知：
