介绍研究结果,往往一个句子指出反映完整研究结果的图表;
概述最重要的研究结果;
对研究结果作出评论或概括,及由这些结果得到的推论。

在结果部分的开始以及结果部分各段落的前面,通常出现介绍研究结果的句子,用于指出研究结果在哪个表格或图形中给出:
shows the influences of operating fragmentation on char loadings.
Data in Table 3 show that operating and capital costs of DiCTT technology are significantly lower.
The effect of having higher turbine inlet temperature on the cycle thermal efficiency is shown in Figure 4.
时态:
此类句子都使用一般现在时态,常用show, present, display, summarize, depict及illustrate.
语态:可被动也可主动。
还有一种方法是直接陈述结果:
At night the average hourly heat release from storage is massive (see Fig. 3).
At night the average hourly heat release is massive, as shown in . or as shows. 或放在句首。

1)时态:
一般采用一般过去时,表明作者在这些研究过程中在某特定情况下出的结果;
如作者想表达自已的结果具有普遍有效性,可用一般现在时;
一般而言可用不同时态表明结果的不同有效范围;
在许多学术领域,在叙述研究结果用一般过去时。
2)科技论文中,作者常常必须叙述的研究结果:
A. 某个参数或变量在某段时间内的变化情况;
B. 不同试样、方法或研究对象之间的比较;
C. 不同参数或变量之间的关系或影响。
表达参数或变量在某段时间内变化的基本句型:
The enhancement factor increased when the applied voltage was from 0 kV to 20kV.
The pressure /the number of postgraduates in the school decreased/
Rose/fell/dropped/declined/went up/went down/remained constant/ remained unchanged after more heat flux was added /from 1998 to 2000.
不同试样方法或研究对象之间比较的基本句型
The power throughput of the condenser increased much slower than that of the evaporator.
The fastest algorithm was the ic algorithm.
Sample 1 had the highest ic resistance.
The temperature difference between the cases with and without anthropogenic heat was smallest near dawn.
不同参数或变量之间关系或影响的基本句型
Pressure was correlated with the ambient temperature.
/negatively correlated with
/dependent on/independent of /determined by/closely related to
