9、e present experiment, the ice water slurry velocity, ui, ranged from 0.15 to 0.6 m/s, the IPF of ice water slurry at the test section inlet, IPFin, between 0 and 15%, the hot water temperature, Thin, between 20 and 30, and the hot water velocity, uh=0.35m/s.第10页Discussion Discuss with your classmate

10、s about what methods or theories are usually used in your specialties.第11页正文_研究结果 普通而言，结果部分内容包含以下三个主要项目：介绍研究结果，而且往往以一个句子指出反应完整研究结果图表。概述最主要研究结果。对研究结果作出评论或概括由这些结果得到推论。以上三个项目可能含在几个段落中屡次出现。而且每个段落通常由这三个项目组成，段落第一句为第一个项目，第二个项目是段落主要部分，第三个项目则是由段落最终一、两个句子表示。第12页正文_研究结果例Results（介绍研究结果）Table 1 shows that the me

11、asured drop Texh caused in the temperature of exhaust gases between the inlet to the heat exchanger and the exit from it is considerably more than what was predicted by modeling studies. （叙述最主要结果）Thus, referring to Table 1, it is observed that the Texh values measured on the actual setup are conside

12、rably above the predicted values. This occurrence is especially striking at the tower inlet temperature. （推论）These observations signal that the modeling was on the conservative side.第13页正文_研究结果介绍研究结果句子：时态应用：使用普通现在时态，而且其动词惯用show、present、display、summarize、及illustrate。注意：当图表用于作某种总结时，才可使用summarize,而illu

13、strate只有在指图形时才可使用。第14页正文_研究结果语态使用： 能够采取被动语态或主动语态。前者把结果内容作为主语，后者则把图表名称看成主语。介绍研究结果句子究竞采取被动语态还是主动语态，取决于句子强调内容及主语部分长度。因为结果部分焦点是结果本身，所以在介绍研究结果时，最好把名词短语作为主语，此时句子采取被动语态。不过，名词短语作为主语很长时，会使整个句子出现不平衡、不自然结构，此时宜把图表名称作为主语，句子采取主动语态。第15页正文_研究结果第一类句型：Fig.5 shows the influences of secondary fragmentation on char load

14、ing.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 Fig.4.第16页正文_研究结果第二类句型:直接陈说结果，并在句子中插人一个短语或括号中说明，以告诉读者这些结果在哪个图表中示出。第17页正文_研究结果At night the average ho

16、ight the average hourly release from storage is massive.As Fig. 3 shows, at night the average hourly release from storage is massive.第18页正文_研究结果叙述研究结果句子：在叙述研究结果或对结果作总结时，因为所述内容是过去事件事实，所以通常采取普通过去时态。表示研究过程中得到含有普遍性结果，可用普通现在时。由数学模型和理论推到得到结果，往往用普通现在时。第19页正文_研究结果科技论文中，作者经常必须叙述研究结果为：某个参数或变量在某段时间内改变情况。在这种句子中

17、，被研究参数或变量常作为主语，而表示时间段短语通常位于句末。第20页正文_研究结果第21页正文_研究结果 不一样试样、方法或研究对象之间比较:在进行比较时句子中常出现形容词、副词比较级、最高级。第22页正文_研究结果不一样参数或变量之间关系或影响。惯用句型包含含有如correlated、related等动词句子以及包含描述其中一个参数或变量改变从句复合句。简单句：第23页正文_研究结果复合句：第24页正文_研究结果说明或评论研究结果：作者对研究结果评论或说明通常包含以下内容之一:依据本人研究结果作出推论。如：The results suggest that 作者解释研究结果或说明产生研究结果原

18、因。如:These findings are understandable because 作者对此次研究结果与其它研究者曾发生结果作比较。比如提出自己结果是否与其它研究者结果一致。These results agree with Gerners analysis, in that 第25页正文_研究结果作者对自己研究方法或技术性能与其它研究者方法或技术性能进行比较，这种比较常出现在工程类研究论文中。比如：The recognition rate of our system is significantly higher than that reported for Tokens system

19、.作者指出自己理论模型是否与试验数据符合。如:The measured temperatures along the heat pipe were all highly consistent with the predictions of the theoretical model.第26页正文_研究结果在对结果进行评论或说明句子中，正确动词时态应该依据评论或说明内容而定。 当评论内容为据研究结果作出推论时，句子主要动词通常使用普通现在时态，且惯用appear、suggest、seem推测动词或情态动词may。The contact angles may have effect on the

23、y加动词原形或普通过去时态。第31页作者认为对结果说明含有普遍有效性，则在从句中使用普通现在时态。It seems that ash deposition of Coal P accelerates mainly through thermophoresis.若作者比较不确定此说明是否含有普遍有效性时，则使用may加动词原形形式；It seems that ash deposition of Coal P may accelerate mainly through thermophoresis.第32页正文_研究结果若作者认为说明范围只限在自己研究特定情况，则使用普通过去时态。It seems

24、 that ash deposition of Coal P accelerated mainly through thermophoresis.注意：为了使句子愈加简练，能够将先行主语it开头句子改写成简单句。此时原复合句中从句主语变成简单句中主语，而改写句中动词用普通现在时态。比如，上例句子可改写为：The ash deposition of Coal P seems to accelerate mainly through thermophoresis.第33页正文_研究结果当评论内容为比较作者研究结果与其它学者研究结果时，应该使用普通现在时态，因为不论两组结果之间是不是一致，这个比较是

25、一个不受时间影响逻辑上关系。这类句子中假如存在以that引发从句，那么，从句中动词也用普通现在时态。These results agree well with the findings of Casadio, et al.These data are consistent with earlier findings showing that the best alloying addition is trivalent Ga.第34页正文_研究结果当评论内容是对作者本身采取方法或技术性能与其它作者曾提出方法或技术性能进行比较时可采取普通现在时态或普通过去时态。若在评论中使用普通现在时态，则意味

26、着作者认定句子内容含有普遍有效性，如：The recognition rate of our system is significantly higher than that reported for Tokens system.若使用普通过去时态，则说明作者认为评论范围仅在特定情况下才有效，如：The values predicted our model had a smaller degree of error than the values generated by Bakers model did.第35页正文_研究结果 看成者指出由自己理论模型所得到预测与试验数据之间吻合程度时,通常

27、得使用普通现在时态，说明模型预测与试验数据是不是一致不受时间影响。若这类句子中出现以that开头从句，则从句中亦使用普通现在时态。如：The data confirm closely the prediction of the model.The data indicate that the model is reliable and accurate.The theoretical model agrees well with the experimental data.第36页正文_研究结果The experimental measurements are very close to th

28、e predicted values. There is a high level of agreement between the theoretical predictions and the experimental data.不过，也有作者把推测和试验数据之间比较视为一个过去行为，因而在句中采取普通过去时态。第37页Read the following section of Results to find out what hypothesis this paper must have proposed. Note the tenses of the words underlined.

43、ained largely by hunting but model fit was improved with the addition of predation mortality. Food supply was only a factor in areas where hunting was least, namely the east and south. In addition, our spatial results are consistent with the trends in the elephant population (Sinclair et al. , ). El

44、ephants behave more as one cohesive population, which moves away from disturbed areas and finds sanctuary in more peaceful areas, so that densities are a reflection of movements.Buffalo on the other hand are extremely philopatric and remain within their home range irrespective of the disturbance (Si

The buffalo populations in close proximity to areas with higher rates of human settlement had low or negative intrinsic rates of population increases and, therefore, were either slowest to recover or failing to recover a
