论汉语广告语篇的人际意义

根据Halliday的功能语法,人际功能是语言三大元功能之一。广告作为一种特殊的语体有着自身的语篇特征。该文旨在采用系统功能语法和评价理论为框架,以汉语化妆品广告语篇为载体,从语气,情态和和评价三个角度分析了6篇汉语化妆品广告的语言特征,证明这些广告中运用的语气和情态具有一定的规律性,且与广告所传递的人际意义密切相关。分析同时证明系统功能语法和评价理论能够有效地指导汉语广告语篇分析的实践。

Application of Block Copolymer in Three-Liquid-Phase Extraction System

Introduction Polyethylene oxide-polypropylene oxide-polyethylene ox-ide (PEO-PPO-PEO) block copolymers are non-ionic surfactants and include hydrophilic PEO and hydro-phobic PPO segments. Due to the presence of PPO central block, PEO-PPO-PEO copolymers ha…     

Nonnegative matrix factorization and its applications in pattern recognition

Matrix factorization has been widely used in many fields[1]. In numerical algebra, the large-scale and com- plex problems can be transformed into small-scale sim- ple subproblems by matrix factorization; in applied statistics, low rank approximation of or…     

Magnetostratigraphic study of Cretaceous depositional succession in the northern Kuqa Depression, Northwest China

Stratigraphic studies on the depositional succession in the Kuqa Depression can be traced back to as early as 1950s[1], however, there are still some disputes about chronostratigraphic division of the Bashenjiqike For- mation because of the paucity of fos…     

Eolian origin of the Miocene loess-soil sequence at Qin’an, China: Evidence of quartz morphology and quartz grain-size

Recent study revealed that the so-called Neogene Gansu System in the western Loess Plateau contains loess-soil sequences of Miocene age. A most complete sequence （QA-I） covers a time interval from ～22 to ～.6.2 Ma BP, consisting of more than 230 visually definable paleosols interbedded with loess layers. A loess-soil sequence of late Miocene-Pliocene age, synchronous with the Hipparian Red Clay in the eastern Loess Plateau, was also recognized, and extends the Miocene sequences into the Pliocene, ～3.5 Ma BP. Recently, Miocene eolian deposits were also reported from the high terraces near Xining.
