军事用语语义泛化缘由探析

军事用语语义泛化的原因主要有两点:一是从语言系统外部来看:主要与语用环境的相似、言语修辞活动、言语交际中的心理因素等社会文化语用条件有关联;二是从语言系统内部来看,主要与语言的经济性原则密切相关。     

索绪尔语言学理论中的三组重要术语的中文译名

对于索绪尔语言学理论中的几组重要术语，国内学者所使用的译名各不相同。文章对其中三组术语langage、langue、parole，signifiant（signifier）、signifié（signified），syntagmatique（syntagmatic relations）、associatif（associative relations）or paradigmatique（paradigmatic relations）的中文译名作了较为翔实的考证，在此基础上提出关于这三组译名的观点，并分析译名未得到统一的原因及其产生的影响。     

岩芯筒压入地层的塑性力学问题

摘要首先从库仑定律出发导出了地层介质塑性流动条件。其结果类似于一般塑性力学中的Tresca,Mises条件。其次列出了轴对称地层塑性流动的微分方程组,并推出了其简化近似方程。最后提出了简化方程的特征线解法,并举例说明。     

Orthogonally linear polarized lasers(Ⅰ)--principle and devices

Two kinds of orthogonally polarized lasers, i.e. Zeeman dual-frequency lasers and four-frequency ring lasers (laser gyros) have been developed since the invention of lasers, in which circularly polarized lights oscillate. This paper summarizes recent progress of the study on orthogonally linear polarized lasers with the standing wave cavity. Firstly, the expression of producing orthogonally linear polarized lights in standing wave cavity, i.e. laser frequency splitting, is given. Almost all the birefringence effects made in laser cavity are used to produce orthogonally linear polarized lights. The effect includes quartz crystal birefringence effect, calcite birefringence effect,stress (photo-elastic) birefringence effect and electro-optical birefringence effect. Secondly, several physical phenomena of orthogonally linear polarized lasers are discovered such as aberrance of frequency splitting curves caused by optical activity of quartz crystal, order-passing of longitudinal modes with frequency splitting and strong modes competition. Finally, because the traditional Zeeman dual frequency laser cannot output frequency difference larger than 3 MHz, the approaches of obtaining larger frequency difference are studied. The sequential results, several kinds of orthogonally polarized lasers, are described, such as birefringence dual frequency lasers outputting a frequency difference from 40 MHz to hundreds of megahertz, birefringence-Zeeman dual frequency lasers outputting a frequency difference from 1 MHz to hundreds of megahertz, the LD pumped YAG birefringence dual frequency laser outputting frequency difference of several gigahertz, and the lasers whose longitudinal mode spacing is c/4L instead of c/2L.

Shear-wave splitting and anisotropy in crust of Dabieshan orogenic belt

The shear-wave splitting was analyzed on the deep seismic sounding profile crossing the Dabieshan area. The direction difference between Sg and SmS fast wave polarization indicates that the modem regional tectonic stress field in the Dabieshan area exists only in uppcr crust, while the crack alignment caused by the Triassic collision between the North China and the Yangtze blocks had been preserved in mid-lower curst.
