从The Da Vinci Code两译本看翻译规范与译者思维的互动

本文以The Da Vinci Code大陆和台湾的两个中译本的描述研究为例,来验证译者的翻译策略是否遵循或违背规范。从描述研究中得出结论,翻译过程是一个极为动态多变的过程。对翻译规范与译者思维互动的研究,正是为了更动态的还原多变的翻译过程,从而对翻译实践提供借鉴与帮助。     

电子邮件六大疑问

一、如何收发电子邮件,该做些什么? 首先选择一种E-MAIL软件,目前网络上常用的有Netscape、Outlook Express、Foxmai等。当您安装好E-MAIL软件后,首先要做的是将您的E-MAIL信箱参数设置在该软件中,设置好后,自己给自己发封信,如能正常收发那就证明你设置成功了。收发信件     

中心法则的发展和面临的挑战

回顾经典中心法则由萌芽到产生和修正的历史过程。阐述和论证中心法则的发展和其新的外延和内涵，指出遗传信息的传递是多维的，非共性的；遗传信息的传递是延续的开放的，并结合朊病毒探讨中心法则面临的挑战。展望其发展趋势。     

Scaling behavior of nucleotide cluster in DNA sequences

In this paper we study the scaling behavior of nucleotide cluster in 11 chromosomes of Encephalitozoon cuniculi Genome. The statistical distribution of nucleotide clusters for 11 chromosomes is characterized by the scaling behavior of P（S） ∝ e^-αs＇ where S represents nucleotide cluster size. The cluster-size distribution P（S1＋S2） with the total size of sequential C-G cluster and A-T cluster S1＋S2 were also studied. P（S1＋S2） follows exponential decay. There does not exist the case of large C-G cluster following large A-T cluster or large A-T cluster following large C-G cluster. We also discuss the relatively random walk length function L（n） and the local compositional complexity of nucleotide sequences based on a new model. These investigations may provide some insight into nucleotide cluster of DNA sequence.

分析了密码学的两种密码算法：对称密钥体制的代表DES算法和非对称密钥体制的代表RSA算法各自的优缺点,提出了将两种算法结合的组合数据加密算法的数据模型及算法设计,探讨了密钥的管理和分配问题以及保证网络数据安全问题。     

噬菌体的遗传物质都是双链DNA吗

在赫尔希（A．Hershey）和蔡斯（M．Chase）所做的证明DNA是遗传物质的经典实验“噬菌体侵染细菌的实验”中，两位科学家所用的噬菌体为大肠杆菌的T2噬菌体，T2噬菌体的遗传物质为双链DNA。由于受该实验的影响，许多老师和学生认为噬菌体的遗传物质都是双链DNA，其实不然。     

破译“成长密码” 支持儿童成长之一 夫妻关系和为贵

小学一二年级,家庭总是处于激烈争吵中,到了三四年级时,家庭基本处于破裂状态。这种家庭的纷争某种程度上促进了我的成长,但它的负面作用也是明显的,让我愈加沉默。我开始更依靠自己,到了现在,我更信赖自己而不是别人,遇到事情总是单独解决(虽然这种解决问题的方法效率不高且容易犯错)。[材料提供:华中科技大学学生]

Evaluation and application of an efficient plant DNA extraction protocol for laboratory and field testing

Nucleic acids in plant tissue lysates can be captured quickly by a cellulose filter paper and prepared for amplification after a quick purification.In this study,a published filter paper strip method was modified by sticking the filter paper on a polyvinyl chloride resin(PVC)sheet.This modified method is named EZ-D,for EASY DNA extraction.Compared with the original cetyl trimethylammonium bromide(CTAB)method,DNA extracted by EZ-D is more efficient in polymerase chain reaction(PCR)amplification due to the more stable performance of the EZ-D stick.The EZ-D method is also faster,easier,and cheaper.PCR analyses showed that DNA extracted from several types of plant tissues by EZ-D was appropriate for specific identification of biological samples.A regular PCR reaction can detect the EZ-D-extracted DNA template at concentration as low as 0.1 ng/μL.Evaluation of the EZ-D showed that DNA extracts could be successfully amplified by PCR reaction for DNA fragments up to 3000 bp in length and up to 80%in GC content.EZ-D was successfully used for DNA extraction from a variety of plant species and plant tissues.Moreover,when EZ-D was combined with the loop-mediated isothermal amplification(LAMP)method,DNA identification of biological samples could be achieved without the need for specialized equipment.As an optimized DNA purification method,EZ-D shows great advantages in application and can be used widely in laboratories where equipment is limited and rapid results are required.     

DNA芯片技术及其应用

DNA芯片技术是近年发展起来的DNA分析技术，它采用高速打印或光刻合成技术可在硅片、玻璃或尼龙膜上制造DNA微阵列，样品DNA通过PCR扩增、体外转录等技术掺入荧光标记分子，与微阵列杂交后，通过荧光扫描仪扫描及计算机分析即可获得样品中大量基因序列及表达信息，该技术可应用于DNA序列测定、基因表达水平检测、基因及多态性检测、发现新基因等多个研究领域。
