中、英文摘要写作
摘要内容独立于正文而存在,它能否准确、具体、完整地概括原文的创新之处,将直接决定该文是否被收录、阅读和引用。中文摘要以200～300字为宜,英文摘要100～150 words左右。中英文摘要内容应一致，背景信息应取消或减少，摘要应回答好如下4个方面的问题:
（1）直接写出研究目的。主要说明作者写此文章的目的,或要解决的主要问题;（2）详细陈述过程和方法。说明作者主要工作过程及所用的方法,也包括众多的边界条件,使用的主要仪器和设备;
（3）明确列出结果和结论。罗列作者最后得到的结果和结论。如有可能,尽量提及作者所得结果和结论的应用范围和应用情况;
（4）通过（2）和（3)两方面内容具体展示文中的创新之处。
中、英文关键词写作
关键词作为文献索引以便于检索该文，应选取能反映论文主题概念的词或词组，一般每篇文章标注3～8个。关键词必须从论文题名、摘要中选取，用名词或名词性词组表达，避免使用非规范的缩写词。中、英文关键词应完全对应。
以下为摘要的实例，每个例子中、英文摘要是对应的。

Abstract: （目的）To improve the current analysis of basic variable importance, （方法和过程）a new moment independent importance measure system, including total importance measure, mean total importance measure, main importance measure and mean main importance measure, is established based on the present single moment independent importance measure. Those indices are used to evaluate the effects of basic random variable on the whole uncertainty of the output of system or model under different requirements. After definitions of those importance measures are given, their engineering significations and applications are illustrated in detail. The solution of the proposed measures is provided based on the probability density evolution method due to its merits. （结论）Two examples are used to demonstrate that the proposed importance measure system is more reasonable than the existing systems, and the proposed solution can improve computational efficiency substantially with acceptable precision.

摘要：（目的）为从理论上分析研究回流燃烧室弯曲段冲击扰流柱 逆向对流 气膜冷却结构的传热特性,（方法和过程）设计了多种不同几何尺寸的计算模型,运用Fluent软件从流动与换热两个方面对其进行了系统的研究,（结论）得出了如下结论:(1)扰流柱的存在强化了冷却空气在冲击腔中的扰动,使得冷却空气与冷侧壁面的换热得到大大地加强,提高了复合冷却结构的冷却效率;(2)在本文研究的几何尺度下,附着于弯曲段热侧壁面的气膜层有效长度最大弧度不超过10°;(3)吹风比对复合冷却效率有很大的影响,在冷却壁面冷却效率随吹风比的增加而增加,但当吹风比M>15时,吹风比对冷却效率的影响已不明显;(4)扰流柱的排列形式对冷却效果的影响不大。

Abstract: （目的）To theoretically study the heat transfer characteristics of impingement pin fin＋reversed convection＋film cooling in curved section of combustion chamber,（方法和过程） the flow and heat transfer characteristics of several models are analyzed by numerical simulation using fluent software, and the effects of geometry dimensions on film effectiveness are also studied.（结论） The research results show that: (1) The pinfin between the impingement plate and the film hole plate greatly disturbs the flow in the impingement space, and the convection heat transfer between cooling flow and the heating wall is enhanced so the cooling effectiveness for the composite cooling structure is increased because of the pinfin. (2) Under the geometrical dimension of this paper, the effect length of the cooling film on the curved heating wall is less than 10°. (3) The blowing ratio has a great effect on the effectiveness for the composite cooling structure, and the cooling effectiveness is increased with the increase of blowing ratio, but when the blowing ratio is larger than 15, the effect of blowing ratio on the effectiveness can be neglected. (4) The arrangement of pinfin has little effect on cooling effectiveness.
