　　a . 基本特性

　　d.  语法修辞

　　e.  一个典型示例

　　f. 化学常用句式

　　 时态

　　以一般现在时为主，也使用一般过去时和现在完成时

　　说法一：从理论上讲：

　　一般现在时 通过科学实验取得的研究结果、结论，揭示自然界的客观规律

　　一般过去时 在一定范围内所观察到的自然现象的规律性认识，这种认识也许有一定的局限性

　　现在完成时 表明过程的延续性，虽某事件(或过程)发生在过去，但强调对现实所产生的影响

　　以一般现在时为主，也使用一般过去时和现在完成时

　　说法二： EI 数据库建议：

　　用过去时态叙述作者工作;

　　用现在时态叙述作者结论。

　　说法三

　　论文是通过科学实验揭示客观真理。所取得的结果，无论是过去，还是现在或将耒都是如此。故常用现在时表达。

　　过去时“表达一件过去发生过的事，而且现在已经完结了。”如文中指出发生的日期和时间是写文章之前，必须用过去时，例：This was first known in 1930.

　　许多论文，虽然是作者过去做的工作和得到的结论，然而这些工作和结论并不是达到“完结了”的阶段，而是还会有人，也可能是作者本人，继续研究下去，从而产生进一步的改进和完善。从这一角度出发，可以用现在完成时来描述已做过的工作，以表达这种延续性。例：Man has not yet discovered an effective cure for the common cold.(人类至今尚未发现一种有效治疗感冒的方法。)句中隐含着估计一段时间后也不会发现，但是将耒能否会有，尚有待事实来说明。
      举例

　　一般现在时及其被动语态

　　PET films uniaxially drawn in hot water are studied by means of conventional DSC and modulated DSC (MDSC). …… Variations of Tg with the water content and with the drawing are discussed in terms of the structure in these materials. The increments of ΔCp at Tg are also interpreted using a three phases model.

　　一般过去时及其被动语态

　　An analysis of the cure kinetics of several different formulations composed of bifunctional epoxy resins and aromatic diamines was performed. …… All kinetic parameters of the curing reaction were calculated and reported. Dynamic and isothermal DSC yielded different results. An explanation was offered in terms of different curing mechanism which prevail under different curing conditions. A mechanism scheme was proposed to account for various possible reactions during cure.

　　现在完成时及其被动语态

　　The partial molar enthalpies of mixing of NaHSO4 and KHSO4 have been measured at 528K by dropping samples of pure compounds into molten mixtures of NaHSO4 and KHSO4 in Calvet calorimeter. From these values the molar enthalpy of mixing has been deduced.

　　The phase diagram of this system has been confirmed by conductometric and thermal analysis methods. By an optimization method the excess entropy of the liquid mixtures was also calculated.

　　应理解为上述时态是撰写摘要时常用的几种时态，有时很难区分它们在含义上的严格差异。

　　关于结构式文摘

　　据统计，目前世界上约有60%的核心生物医学期刊采用结构式摘要，但此种摘要不适合综述之类的文章。

　　结构式文摘是按Objective(目的)、Methods(方法)、Results(结果)和Conclusions(结论)逐一阐述论文的梗概。在Objective项，可直接用动词不定式的一般式主动语态，如To provide, To explore, …; Methods和Results 项，可用一般过去时(有时也用现在完成时)及其被动语态;Conclusions 则用一般现在时(参见：韩仲琪，李炳汝，王庆法. 医学论文英文摘要格式及其写作问题. 编辑学报，2002，14(6)：412)

　　Objective

　　动词不定式开头

　　To investigate …

　　To study …

　　To explore …

　　To examine …

　　To determine …

　　To report …

　　To review …

　　使用第一人称时，用凡指的we, the author, the authors ,不用I。

　　如：In this paper we conclude …

　　Methods

　　用完整的句子，以被动句和过去时态为主。

　　Results

　　用一般过去时陈述实验结果。

　　Conclusions

　　集中表达作者的学术观点。

　　(1) 力求简捷

　　at a temperature of 250℃ to 300℃ → at 250 to 300℃

　　at a high pressure of 2 kPa → at 2 kPa

　　has been found to increase → increased

　　from the experimental results, it can be concluded that → the results show

　　(2) 能用名词作定语的不用动名词作定语，那用形容词作定语的不用名词作定语

　　measuring accuracy →measurement accuracy

　　experiment results →experimental results

　　(3) 可直接用名词或名词短语作定语的情况下，要少

　　用of句型

　　accuracy of measurement → measurement accuracy

　　structure of crystal → crystal structure
        (4) 可用动词的情况尽量避免用动词的名词形式

　　Measurement of thickness of plastic sheet was made →

　　Thickness of plastic sheet was measured

　　(5) 一个名词不宜用多个前置形容词来修饰，可改用

　　复合词，兼用后置定语

　　thermal oxidation apparent activation energy →

　　apparent active energy of thermo-oxidation

　　5 一个典型示例

　　A detailed study of the melting behavior of oriented isotactic polypropylene has been carried out using differential scanning calorimetry. The orientation in isotactic polypropylene was produced by extruding it in solid phase. At extrusion ratio (ER ) greater four, two melting peaks were observed. With increasing ER, the lower temperature peak was found to shift to higher temperature. The corresponding shift in the higher temperature peak was much less. It is shown that these peaks originate in the melting of crystalline species having different degrees of crystal disorder and stereo-block character.
