内容提要

除非目标期刊的指南有特殊要求，摘要需要包含问题陈述、动机、方法、结果和结论五个要素。本文针对每个要素给出一些常用的句型。

句型举例中， A代表作者, C代表特征，D代表领域或方向，E代表某个解释或定义, M代表方法，P代表问题， R代表原因，X代表现象、规律等，O代表其他。对应的小写字母则代表子类或细分，例如，d代表D中的细分方向。摘要举例取自于文献【1】。

问题陈述常见句型

problem statement

陈述要解决的问题是什么，这个问题有什么地位或重要性。对于受益面比较大的问题，先用通俗易懂的语言陈述所有科学家都懂的部分，再陈述同行科学家才懂的部分。对于只面向同行科学家的论文，如果论文的标题和摘要中指出的动机很明显地带出了是什么问题，那么可以忽略这个要素。

问题陈述常见句型

a.X is defined as  E, and this problem is important  for (or key issue in)  D.    Though  much work has been done concerning P, the related questions about  p are little addressed (or not considered, or not thoroughly considered).  Understanding these questions is of primary importance (or significant ) in d.

b.P is a hotly studied topic due to the widespread  recongnization  of the importance of this problem in D. Unfortunaturely, the p of P is little addressed (or not considered) due to the lack of (or owing to or for reason of) R.

c.p is an important component in P and plays a key role in d.

d.R is the leading cause of X frequently observed in p.

e.M  is among the most widely used methods and

f.X is a well-known phenomenon  characterized by C.

g.The issue of p in P has received considerable  attentions because of its importance in D.

h.p is an increasingly important issue in D.

举例：

The habitable zone (HZ) is commonly defined as the range of distances from a host star within which liquid water, a key requirement for life, may exist on a planet’s surface. Substantially more CO2 than present in Earth’s modern atmosphere is required to maintain clement temperatures for most of the HZ, with several bars required at the outer edge. However, most complex aerobic life on Earth is limited by CO2 concentrations of just fractions of a bar. At the same time, most exoplanets in the traditional HZ reside in proximity to M dwarfs, which are more numerous than Sun-like G dwarfs but are predicted to promote greater abundances of gases that can be toxic in the atmospheres of orbiting planets, such as carbon monoxide (CO).

可居住区(HZ)通常被定义为作为生命的一个关键要素的液态水可以存在于行星表面的离宿主恒星的距离范围。对于大多数可居住区，为了维持温和的温度，要求二氧化碳比地球现代大气中的二氧化碳多得多， 且在外边缘有几个巴的气压。然而，地球上最复杂的有氧生命受几分之一巴二氧化碳浓度的限制。与此同时，位于传统宜居带的大多数系外行星都位于M矮星附近，这种矮星比类太阳的G矮星数量更多，但据预测这会使在轨行星大气中更富有一氧化碳等有毒气体。

动机常见句型

motivation or purpose

动机用于指出论文要解决的具体问题是什么，必要时指出目的，适当指出解决这个问题的重要性和困难。

动机常见句型

a.Here we show (or demonstrtae) that  X .

b.This study aims to elucidate R of X observed in p.

c.The main objective/goal/purpose of the paper/article is to introduce a  M (or elucidate R or explain the cause of X).

d.Here (or in this paper)  we study (or address or consider) p (or X or M).

e.p (or X or M)  is considered in this paper.

f.This paper is concerned with p (or X or M).

g.The paper/article discusses (or deals with, analyses, considers, explains, describes, establishes a method for,  aims on, offer a solution to) p (or X or M).

h.This paper develops M (presents M, provides M, studies X, contains R,  concentrates on R)

i.This paper gives (or aims to give ) a comprehensive account of R.

j.This paper presents a novel M for R that exists in p of P.

举例：

Here we show that the HZ for complex aerobic life is likely limited relative to that for microbial life.

在这里，我们指明，相对于微生物生命，适应于复杂有氧生命的宜居带（数目）可能受限。

03

方法常见句型

method

简述论文所采用的研究方法。对于读者所不熟悉的方法，应指出方法的特征和方法的来源。

方法常见句型

a.We use the method  M for p and this method has the properties of C.

b.M is used in this paper.

c.Systematic M (experiments or numerical simulation or case studies or surveys or theoretical analyses ) are performed with

d.To solve p (or to reveal X) , a method based on m is proposed here and this method is capable of .

e.We build M for X and this method is updated from the method of A through introducing m to increase the accurary (or robustness or parameter range).

举例：

We use a 1D radiative-convective climate and photochemical models to circumscribe a Habitable Zone for Complex Life (HZCL) based on known toxicity limits for a range of organisms as a proof of concept..

我们使用1D辐射对流气候和光化学模型，根据一系列生物的已知毒性极限，划定复杂生命可居住区，以作为（我们提出的）概念的证明。

04

结果常见句型

result

呈现论文得到的最重要/主要的结果。如果是定量结果，应量化到最后一级。如果是定性结果，应使用没有歧义的表述方式。

结果常见句型

a.We find that for ...

b.One of the important results is that x1, another one is that x2.

c.The results are X.

d.We obtain the results of or that X

e.It is demonstrated that R is the reason of x.

h.The most striking observation from the data  was

i.The most striking finding of this study was

j.The x1 and x2  are here found to be dependent on

举例：

We find that for CO2 tolerances of 0.01, 0.1, and 1 bar, the HZCL is only 21%, 32%, and 50% as wide as the conventional HZ for a Sun-like star, and that CO concentrations may limit some complex life throughout the entire HZ of the coolest M dwarfs.

我们发现，对于气压为0.01、0.1和1巴的二氧化碳容差，复杂生命宜居带的宽度仅为类太阳恒星常规宜居带的21%、32%和50%，并且CO2浓度可能会限制最冷的M矮星整个宜居带的某些复杂生命。

05

结论常见句型

conclusion

声明结果对同方向的问题有什么含义、影响和价值。对于综合性期刊，还要求指出对其它或所有领域的问题有什么意义。对于非常专业的期刊或论文，如果结果本身的意义对于潜在读者很明确，则不需要特别强调结论。

结论常见句型

a.These results cast new light on (or have important ramifications for )   p.

b.The present study bridges the gap between  p1 and p2.

c.The present study establishes a link between  x1 and x2.

d.This study closes up a long debate about  R.

e.The conclusion of this study is that

f.The result obtained by this study can be used to (or applied to）

g.This study opens up a new field （or issue） in P.

h.This study not only solves the challenging problem of P but also offers a method that can be used to solve other problems such as  p1 and p2.

举例：

These results cast new light on the likely distribution of complex life in the universe and have important ramifications for the search for exoplanet biosignatures and technosignatures..

这些结果给宇宙中复杂生命的分布带来新的见解，且对寻找外行星生物特征和技术特征有重要延伸意义。

以上句型假定了论文的五个要素分布在不同句子中。有时，可以用一些特有的句型将两个或多个要素概括在一个句子中，例如，以下句型就将方法、结果和结论紧密地结合在一句话中：

通过使用档案分析和调查分析相结合的方法，我们发现学生修业年限与进出图书馆的频率的相关性系数高达0.5，这一结论可用于督促学生将更多时间花在图书馆中。
