语言适应论视域下科技翻译锥形图的建构

根据语言适应论的基本观点,以语言表义为中心的科技翻译锥形图才得以科学地建构。语言表义功能既是一切科技翻译活动的出发点和生长点,又是涌现意义与建构意义的结合体,凸显了译者的建构性以及科技翻译的科学性与动态性之间的辩证关系。因此,科技翻译是译者以科技语境为基础将源语的语言表义功能转述为译语的语言表义功能的动态适应与意义生成过程。

利用电磁带隙结构实现锥形方向图

该文采用电磁带隙(EBG)结构层覆盖的方式实现了一种锥形方向图.文中给出了微带贴片天线在覆盖电磁带隙结构前后的反射损耗和方向图特性的变化,并研究了EBG结构悬置高度的影响.实验结果证明了这种锥形方向图实现方式的有效性.

金字塔交际图——与王寅教授商榷

王寅在批判索绪尔的交际循环图、Shannon和Weaver的线形图、Newcomb的三角图及Leech的梯形图的基础上,为突显语义在交际中的关键性作用设计了锥形交际图,强调了语义在语言交际中的核心作用。锥形交际图有较大的优点,即强调了社会情景、语言的社会性及语义的重要性,但交际以语义为中心这样的观点是有失偏颇的,在此模式下,幽默、隐喻的识解将成为遗憾,且锥形交际图的某些环节还有待于进一步商讨。笔者认为,以以语用为主、语义为辅的模式对交际有更强的解释力,并拟画金字塔交际图以强调认知语境和交际意图在交际中的重要作用。最后笔者举例验证了此图的运作机制。

Formation mechanism of subtrenches on cone-shaped patterned sapphire substrate

In this paper, the cone-shaped patterned sapphire substrates (PSS) were etched by an inductively couple plasma with BCl 3 as the reacting gas. The influence of the operating pressure and the RF bias power on subtrenches of the cone-shaped PSS and the formation mechanism of subtrenches were investigated. The profiles of patterns were characterized by FESEM (field emission scanning electron microscope). It showed that the subtrench size varied with the operating pressure and the RF bias power. As the operating pressure increased from 0.2 Pa to 0.9 Pa, the subtrenches changed from narrow and deep to wide and shallow; then to narrower and shallower. When the RF bias power varied from 200 W to 600 W, the subtrenches gradually became noticeable. The FESEM results also indicated that the subtrenches were formed due to the ion scattering effect which was caused by tapered sidewalls and charges accumulation. It is discovered that the scattering effect is closely related with the operating pressure and RF bias power.
