3.Methods We first put forward clinical problems about how to prevent complications and how to treat ruptured aneurysm of aSAH,then searched The Cochrane Library (Issue 4,2006),Ovid ACP Journal Club (1991 to 2006),Ovid MEDLINE (1966 to 2006),NGC (1998 to 2006) and CBM (1978 to 2006) to identify systematic reviews, randomized controlled trials,controlled clinical trials and treatment guidelines.
方法根据所提出的如何预防并发症及处理破裂动脉瘤的问题,全面检索Cochrane图书馆(2006年第4期)、OVID ACP Journal Club(1991～2006)、OVID MEDLINE (1966～2006)、美国国家指南交换中心(1998～2006)及中国生物医学文献数据库(1978～2006),获取并评价相关的系统评价、随机对照试验、临床对照试验证据及治疗指南。
4.We searched randomized controlled trials,meta-analysis and systematic reviews from OVID-EBM Reviews which included ACP Journal Club,The Cochrane Library, and MEDLINE( 1991 to 2005) to evaluate clinical effectiveness of pit and fissure sealants for caries.
为评价窝沟封闭剂防治牙齿窝沟点隙龋病的临床效果,作者检索了从1991~2005年的OVID-EBMReviews(包括ACP Journal Club、Cochrane图书馆)和MEDLINE的随机对照试验、Meta分析和系统评价。
5.Impact Factor has been receiving much attention in our country as a parameter of literature statistics recent years. In network,however,there are two kinds of the impact factors that may be searched for. One is the impact factor of Journal Citation Reports(JCR) given by Information of Science Institute,USA.
影响因子作为文献计量的一项指标近年来在我国收到了广泛的关注,但是,在网络上我们通常能见到有两种影响因子,一种是由美国科学信息研究所(ISI)每年发布的期刊引证报告(Journal C itation Reports,JCR)提供的影响因子;
6.Lucas and Lehmer gave a classical primality test for Mersenne numbers and Benedict presented in a recent paper("An elliptic curve test for Mersenne primes",Journal of Number Theory,2005,110(1),pp.114-119)an elliptic curve test.
Lucas和Lehmer给出了测定Mersenne数的经典方法[1]. 在Journal of Number Theory 110(2005)“An elliptic curve test for Mersenne primes”[2]一文中,Benedict又给出了一种对Mersenne数进行素性测的椭圆曲线测试,但并没有给出两种测试运算量的分析与比较.

8.Professor Becchetti is author of about 230 works, which include 11 edited books, 42 publications on international journals (among them Journal of Banking and Finance, Journal of International Money and Finance, Journal of Economic Behavior and Organization, Journal of Business Ethics, Applied Financial Economics, Economics of Innovation and New Technology, Small Business Economics, Applied Financial Economics, International Journal of Industrial Organization, Review of Industrial Organization), 38 publications on Italian journals, 54 chapters of books and several working papers.
他至今发表了230余部作品，其中包括11本专著，42篇发表在国际刊物上的评论(例如《银行与金融期刊》、《国际货币与金融期刊》、《经济行为与组织杂志》、《商业伦理期刊》、《应用金融经济学》、《创新与新技术经济学》、《中小商业经济学》、《应用金融经济学》、《工业组织国际期刊》、《工业组织评论》)，以及38篇在意大利期刊上发表的文章，54章节的书籍和许多工作论文。
9.The cite situation of 220 treatises from 1985 to 1991 in journal of Luzhou medical college was analysed in terms of price index, and cite situation of 1991 year valume reference in the journal of the other medical college in Sichuan province and the National Medical Journal of China were compared with that of 1991 year valume reference in the journal of Luzhou Medical College.
用普赖斯指数分析泸州医学院学报1985～1991年220篇论著参考文献的引用情况,并用1991年学报与省内其他医学院校学报及中华医学杂志的同类情况比较,发现平均普赖斯指数为50.6％;
10.Based on the tribological principle and the theory of contact mechanics,it is feasible to adopt curvature-changing structure in the Rock-bit journal bearing system.The structure and coupling relationship of curvature-changing journal bearing under the condition without friction have been analyzed and three kinds of sub-form structure configurations,namely,the pseudo-curvature-changing structure,the conformable curvature-changing structure,and the clearance curvature-changing structure,been differentiated according to the contacting features.The shape optimization and pre-running-in regulations of the contact surface of curvature-changing journal bearing under friction condition have been established.The results of Rock bit journal bearing test indicate that the tribological behavior of the bearing can be effectively improved by curvature change based on both designing and pre-running-in.
基于摩擦学原理和接触力学理论,提出了可在牙轮钻头滑动轴承中采用变曲率结构.在不考虑摩擦的情况下，就结构设计和配合关系等问题进行了分析讨论，划分了准变曲率、吻合变曲率以及间隙变曲率等3种结构形式；针对考虑摩擦时的变曲率结构，提出了接触形状优化和预磨合的实施方案.钻头轴承试验结果表明，无论是预设计变曲率还是预磨合变曲率，都能改善轴承摩擦副的摩擦学特性，因而值得进一步研究和推广.
