论信息社会对翻译教学的影响

21世纪是高度信息化的新时代,人类社会的方方面面都受到信息化不同程度的影响,翻译领域也不例外。本文就信息社会对翻译教学的内容和形式产生的影响进行了深入的分析,旨在以信息社会的视野,探索翻译教学的新路。     

北京地区大气气溶胶光学特性及其直接辐射强迫的研究

利用2003年9月－2004年12月天空辐射计观测数据初步反演得到了北京地区大气气溶胶光学特性的参数，包括：500 nm大气气溶胶光学厚度，Angstrom波长指数，单次散射反照率和粒子谱分布的季节变化特征。将反演得到的结果代入辐射传输模式，计算北京地区大气层顶和地面在晴空条件下大气气溶胶的辐射强迫，并分析了其季节变化特征。     

《上博五·三德》简札记二则

《上海博物馆藏战国楚竹书》第五册里有一批简被命名为《三德》。简1中的"句■",整理者读为"後奮",我们认为"句"应该读如本字,古侯切,今音gōu。句,屈生也。奋,发也。"句奮"的意思就是指草木发芽生长。简6中的"■"字,目前学者们有四种通假意见。四种意见虽各有道理,但并不能令人完全信服。我们根据楚地出土古文字材料中的谐声例证,认为"■"通为"虑",训为"乱"。

Anisotropic fluoride nanocrystals modulated by facet-specific passivation and their disordered surfaces

Rutile-type fluorides have been proven to be active components in the context of emerging antiferr-omagnetic devices. However, controlled synthesis of low-dimensional, in particular two-dimensional (2D), fluorides in a predictable and deterministic manner remains unrealized because of a lack of efficient anisotropic control, which impedes their further development in reduced dimensions. We report here that altered passivation of {110} growing facets can direct the synthesis of rutile-type fluoride nanocrystals into well-defined zero-dimensional (0D) particulates, one-dimensional (1D) rods and 2D sheets in a colloidal approach. The obtained nanocrystals show positive exchange bias and enhanced magnetic transition temperature from the coexistence of long-range antiferromagnetic order and disordered surface spins, making them strong alternatives for flexible magnetic devices and sensors.     

Fiḍḍa l-Nūbiyya: The Woman and her Role in Early Shīՙite History

The purpose of the present study is to analyse the role played by an important female figure in early Shī?ite history. The person in question is Fi[ddot][ddot]a l-Nūbiyya, the servant-girl of Fā ?ima, the Prophet's daughter. After a long period of neglect by scholars, who have focused on what to their mind were figures of greater import, we shall here attempt to describe the role played by Fi[ddot][ddot]a in early Shī?ite history by way of analysing her biography and her close relations with Fā ?ima and members of the latter's family (?Alī, [Hdot]asan and [Hdot]usayn). We shall further describe what has been reported of Fi[ddot][ddot]a's personality, her family, her admiration for the Prophet's family, Qur?ānic verses which supposedly mention her, and the great respect in which she was held by Fā ?ima's family.

不同质子酸掺杂聚苯胺的吸波性能研究

采用3厘米波导式测量线在8—14GHz频率范围内，用多点拟合的实验和计算方法对掺杂聚苯胺的微波吸收特性及参量进行了研究．发现：浓H2SO4掺杂本征态聚苯胺(PAn)所合成材料的电损耗很小、磁损耗较大(相对于盐酸聚苯胺而言)，且不利于对微波的吸收：FeCl3掺杂浓H2SO4-PAn材料可合成磁损耗较高、基本上有利于吸收微波的材料；更令人注意的是，利用HCl-PAn具有较大的电损耗，浓H2SO4-PAn—FeCl3材料具有较大的磁损耗这一特点，我们将它们按一定的比例混合，可以合成出平均衰减为13．37dB，最大衰减为26．7dB，密度为0．7g／cm^3、频宽为10．34—14GHz的很有利于吸收微波的材料．     

传播学视阈下的文化媒介属性(下)

媒介是文化的载体,承载着人类数千年以来的历史文化和生生不息的知识、智慧以及人们的思想、观念走进了21世纪。与此同时,各种样式、种类、流派和风格的人类文化,在不断涌现的新的文化媒介、新的传播技术和新的传播方式的支持下,发扬光大、日益繁荣,成为推动社会、经济发展的重要产业。从文化媒介的共享性、传播性、创意性和流通性等方面,论述文化媒介的产业特质。
