Mueller, et. al., 20th Analysis & Computation Specialty Conference) (computer science) Note that comparable options exist in the clauses.1.The effects of tungsten on environmental systems have not been investigated extensively and publisheddata are fragmentary. (Effects of tungsten on environmental systems, Nikolay Strigul, et. al.)(environment engineering)2.Radaj [9] developed a n approach based on Neuber’s micro-structural support hypothesis by suggesting anadditional fictitious radius r f at the notch, which allows the local stress to be analyzed directly withoutrequiring a stress concentration factor or fatigue notch factor [8].

英文科技学术论文Introduction写法

英文科技学术论文Introduction写法

大多数英文科技学术论文都可以使用一种所谓Introduction-Methods-Results and Discussion (IMRAD) 的形式,如下图的沙漏所示,先由普遍到具体问题,再由具体到普遍结论。

这里先总结Introduction的写法和注意事项。

与中文论文“简短”的“概述”(或“前言”)不一样,英文的Introduction内容通常较长。

好的论文在Introduction部分很见功底,文献的阅读量、信息综合能力,可以给读者很多的信息量,因此写好它容不得半点马虎。

Introduction(说明综述)部分的内容通常用来为作者创造一个研究空间。

先介绍目前的研究现状,然后指出存在的不足或尚没有解决的问题,最后再介绍“存在的问题”是“如何”被作者的研究所解决。

因此,Introduction可以由这“三波”或者说“三部分”来组成。

具体而言,这“三波”如此展开:第一波:提出研究现状和此研究的重要性先通过陈述表明所要研究问题的重要性——当然这部分内容不是必须,并介绍此领域的研究现状,具体可参考文献综述引用。

研究问题要与自己的研究内容高度相关,时态一般可用一般现在时,并通过很确定的语气和具体的形容词来强调研究的重要生。

The flow of foams is seen in many process, and its use in major industries means that an understanding of foam rheology is of paramount importance.第二波:强调有必要解决存在的问题指出该研究目前存在的问题,可以通过提问的方式或者通过某种方式扩展此领域已有知识和结论。

这一波非常重要,只有指出存在的问题或尚待解决的问题,才能突显出自己的研究价值。

在这一部分的写作时,一般通过转折词来表示过渡,并在指出问题时使用负面的词汇。

… ; however, the relationship between emergence and soil temperature has not been investigated previously…In contrast to the extensive literature describing ….., little attention has been paid to…第三波:介绍作者自己的研究内容介绍作者的研究目的和大致的研究内容。

Thus, it is essential to elucidate the mechanism of TP-induced hepatotoxicity from a safety point of view.the aim of our study was to identify candidate genes associated with TP treatment and to provide novel insights to better elucidate the mechanisms of toxic effects of TP.主要理论根据及其基本原理Considering that microarray technology is recognized as a reliable toxicologica method to determine mechanisms of drug-induced toxicity, identify biomarkers and to predict chemical toxicity.Therefore, the aim of our study was to identify candidate genes associated with TP treatment and to provide novel insights to better elucidate the mechanisms of toxic effects of TP.同时指出相关领域内前任的研究成果possesses anti-inflammatory, anti-fertility, anti-neoplastic and immunosuppressive activities (Chen, 2001; Huynh et al., 2000; Panichakul et al., 2006).have emerged as treatments of rheumatoid arthritis, systemic lupus erythematosus, nephritis, leprosy and asthma (Lipsky and Tao, 1997; Liu et al., 2005; Zhang et al., 2010).clinical use of TWHF or TP has been limited due to severe adverse reactions, such as gastrointestinal upset, diarrhea, reproductive toxicity and problems associated with circulatory systems (Hikim et al., 2000; Ni et al., 2008; Yang et al., 2012; Zhang et al., 2011).Recently, hepatotoxicity induced by various extracts of TWHF in animals and humans has been reported by many researches (He et al., 2006; Mei et al., 2005; Wang et al., 2007) To date, only mitochondrial respiratory chain inhibition, lipid peroxidation, DNA damage and hepatocyte apoptosis were proposed to be involved in TP-induced liver injury (Fu et al., 2011; Mei et al., 2005; Yao et al., 2008).等存在问题和知识空白Hepatic differential gene expression was analyzed using oligonucleotide microarray analysis for over-represented functions and phenotypically anchored to complementary histopathologic, biochemical, and dosimetry data in the liver. The results indicate that TP affects diverse cellular pathways, including insulin signaling pathway, glucose metabolism, cell cycling, oxidative stress and apoptosis. These data provide a clearer understanding of the molecular mechanisms of TP-induced hepatotoxicity, as well as useful information for predicting drug hepatotoxicity.以表明本项研究的连续性和需要性,叙述有关本课题的历史沿革是为了温故而知新,Triptolide (diterpenoid triepoxide, TP), purified from the shrublike vine Tripterygium wilfondii Hook F (TWHF), possesses anti-inflammatory, anti-fertility, anti-neoplastic and immunosuppressive activities (Chen, 2001; Huynh et al., 2000; Panichakul et al., 2006). Recently, the methanol/chloroform (T2) and ethyl acetate (EA) extracts of TWHF, in which TP was identified as the principal active compound, have emerged as treatments of rheumatoid arthritis, systemic lupus erythematosus, nephritis, leprosy and asthma (Lipsky and Tao, 1997; Liu et al., 2005; Zhang et al., 2010). However, clinical use of TWHF or TP has been limited due to severe adverse reactions, such as gastrointestinal upset, diarrhea, reproductive toxicity and problems associated with circulatory systems (Hikim et al., 2000; Ni et al., 2008; Yang et al., 2012; Zhang et al., 2011).Recently, hepatotoxicity induced by various extracts of TWHF in animals and humans has been reported by many researches (He et al., 2006; Mei et al., 2005; Wang et al., 2007). Besides, Liu et al., (2010) found that potential hepatotoxicity in rats treated with TP for 28 days was associated with increasing levels of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) (Liu et al., 2010). Moreover, it was reported that oral administration of TP to rats could lead to liver injury or even death (Fu et al., 2011). In addition to this, our previous investigation showed that the concentration of TP found in liver exceeds those observed in other tissues, such as spleen, lung, heart, and kidney (unpublished data). On account of this, we hypothesized that liver is a major toxic target of TP treatment. Thus, it is essential to elucidate the mechanism of TP-induced hepatotoxicity from a safety point of view.Unfortunately, its underling mechanisms are still insufficiently recognized. To date, only mitochondrial respiratory chain inhibition, lipid peroxidation, DNA damage and hepatocyte apoptosis were proposed to be involved in TP-induced liver injury (Fu et al., 2011; Mei et al.,2005; Yao et al., 2008). Considering that microarray technology is recognized as a reliable toxicologica method to determine mechanisms of drug-induced toxicity, identify biomarkers and to predict chemical toxicity (Lee et al., 2010; Wang et al., 2011). Therefore, the aim of our study was to identify candidate genes associated with TP treatment and to provide novel insights to better elucidate the mechanisms of toxic effects of TP.Here, we describe genome-wide gene expression in the TP-exposed Wistar female rat liver. Differential gene expression was evaluated in 6-week-old female Wistar rat livers following 14 days of continuous exposure to large doses of TP. Hepatic differential gene expression was analyzed using oligonucleotide microarray analysis for over-represented functions and phenotypically anchored to complementary histopathologic, biochemical, and dosimetry data in the liver. The results indicate that TP affects diverse cellular pathways, including insulin signaling pathway, glucose metabolism, cell cycling, oxidative stress and apoptosis. These data provide a clearer understanding of the molecular mechanisms of TP-induced hepatotoxicity, as well as useful information for predicting drug hepatotoxicity.2.综述Blood vessels, a potential therapeutic target in rheumatoid arthritis?血管,类风湿性关节炎潜在的治疗靶标?IntroductionRheumatoid arthritis (RA) can be defined as a disease of the blood vessels, both micro- and macro-vessels. The formation of new micro-vessels is in fact necessary to afford the nutritional supply to proliferating synovial pannus, while macro-vessels are the site where accelerated atherosclerosis driven by disease’s systemic inflammation develops. New vessels formation on one side, and atherosclerotic plaque progression on the other, might seem two different biological phenomena, the first related to the articular involvement of the disease, the second to its main systemic complication. In this context, targeting blood vessels in RA might mean either attempting to reduce synovial vascular supply starving the synovial pannus limiting its proliferation or, in the other case, trying to limit macro-vessels’damage outside the joint. In this review we will analyse the possibility of targeting synovial microvessels to treat rheumatoid arthritis, but we will discuss as well the evidence supporting a link between micro- and macro-vascular involvements in RA.综述的介绍,介绍所提到物质的基本概念,简要说明课题的缘起与背景,RA与血管生成相关,与血管生成的必要性,在这里,说明该文章立题的主要依据与主要原理,并提出在此综述中接下来会说到的内容,如:作者将分析滑膜微血管治疗类风湿关节炎的可能性,且讨论,血管与RA微观和宏观之间联系的证据。

Work 11 Introduction1.1 AustraliaAustralia is a highly developed capitalist countries, the capital of Canberra, the territory area sixth in the world, rich products, is the most economically developed countries in the southern hemisphere. The twelfth largest economy in the world, the world's fourth largest exporter of agricultural products, and a variety of mineral exports the world's first national. Australia is surrounded by the sea, have a lot of unique plants and animals and the natural landscape.
