科研SCI论文实验写作至发表完全攻略（十一）

◆◆当同时提及几个图、表、方程式时要用复数(分别单个地提及则不用)：The reaction rate constant can be calculated from Equations 2 and 3. The reaction rate constant can be calculated from Equation 2 and Equation 3. Figs. 4 and 5 show ……

C. 冠词：

◆◆单数名词前一般要加冠词：a , the等； 但以下情况可不加：表示不特指的、较抽象的概念：

This chapter will consider the characteristics of step polymerization in detail. An understanding of the relative ease of cyclization or linear polymerization comes from a variety of sources.Different polymers are synthesized to yield various mechanical behaviors by the appropriate combinations of crystallinity, crosslinking, Tg, and Tm..但需注意这些单词前加冠词也是经常见到的，这是由它在句中的含义决定的(如有一定的特指意义)：Polyisoprene is a typical elastomer – it is amorphous, easily crossed, has a low Tg  (-73°C) and a high Tm (14°C).

◆◆目录、标题中通常省略冠词：

1        Introduction

1-1       Types of Polymers and Polymerizations

…

1-4 Molecular Weight

1-5 Physical State

图、表的题目中有时可省略冠词：Fig. 2-2 Second order plot of the self-catalyzed polyesterification of adipic acid with diethylene glycol at 166 °C.……Fig. 8 Dependence of the ease of cyclization on the size of the ring.化学药品、化学物质前通常不加冠词：The polymerization is catalyzed by protonic or lewis acids although a wide variety of base catalysts such as calcium acetate and antimony trioxide can also be used.图中的横、纵坐标的名称前不加冠词。

D. 大小写：请注意以下结构的大、小写：当提及具体第几章、节；图、表；方程式时，首个字母通常要大写。As discussed in Chapter 2, ……In Section 1.2, we ……As shown in Figure 1, ……The results are listed in Table 3.当不指明是第几章、节；图、表；方程式时，首个字母如在句中通常用小写。In the previous chapter, ……As shown in this figure, ……
