科研SCI論文實驗寫作至發(fā)表完全攻略（十一）

◆◆當同時提及幾個圖、表、方程式時要用復(fù)數(shù)(分別單個地提及則不用)：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. 冠詞：

◆◆單數(shù)名詞前一般要加冠詞：a , the等； 但以下情況可不加：表示不特指的、較抽象的概念：

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..但需注意這些單詞前加冠詞也是經(jīng)常見到的，這是由它在句中的含義決定的(如有一定的特指意義)：Polyisoprene is a typical elastomer – it is amorphous, easily crossed, has a low Tg  (-73°C) and a high Tm (14°C).

◆◆目錄、標題中通常省略冠詞：

1        Introduction

1-1       Types of Polymers and Polymerizations

…

1-4 Molecular Weight

1-5 Physical State

圖、表的題目中有時可省略冠詞：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.化學藥品、化學物質(zhì)前通常不加冠詞：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.圖中的橫、縱坐標的名稱前不加冠詞。

D. 大小寫：請注意以下結(jié)構(gòu)的大、小寫：當提及具體第幾章、節(jié)；圖、表；方程式時，首個字母通常要大寫。As discussed in Chapter 2, ……In Section 1.2, we ……As shown in Figure 1, ……The results are listed in Table 3.當不指明是第幾章、節(jié)；圖、表；方程式時，首個字母如在句中通常用小寫。In the previous chapter, ……As shown in this figure, ……
