文化变迁中民间信仰隐性教育功能的消解与反思

民间信仰通过特定的仪式、俗礼、象征,对人的心理、情感、人格、行为等方面产生规范作用,有助于确立稳定的社会道德伦理秩序。由于社会转型、文化变迁及＂科学＂、＂理性＂的现代精神引起了传统与新兴、主流与非主流的文化价值冲突,在这一过程中,居于地方性村落亚文化与意识形态深层结构的民间信仰遭遇到了现代性话语的巨大冲击,其积极的隐性教育功能也处在消蚀和溶解的状态。     

《边城》中模糊数量词的英译及其模糊美感的磨蚀

以杨宪益所译《边城》为例,探讨文中模糊数量词的英译及其模糊美感磨蚀的问题。译者用"以精确译模糊","以模糊译模糊","省略模糊语"等方法欲使英译与原文达到尽可能的一致,但由于英汉语在模糊语言生成机制上的差异,造成了模糊语言美感难以避免的磨蚀。     

不同激光熔覆材料涂层的耐磨性能比较

对宽带激光熔覆不同熔覆材料的复合涂层的耐磨性能进行研究。结果表明Ni60B熔覆层的硬度高于40Cr基材的硬度,Ni60B＋WC梯度复合涂层具有最高的硬度,对于提高零件的抗磨损性能比较有利;Ni60B熔覆层和Ni60B＋WC熔覆层均适合修复轴类零件;三层梯度复合涂层磨痕宽度最小,具有最好的耐磨性。     

低能量激光治疗腰棘上韧带和棘间韧带损伤的临床疗效观察

用半导体激光仪所发生的低能量激光对 32例棘上韧带和棘间韧带同时损伤的病人进行了治疗。病人的平均年龄是 39.31± 1 .5 3岁 ,平均病程是 93.5 9± 2 2 .73天 ,78.1 3%的病人都是在体育活动中受伤。以 1 0度疼痛评分法结合腰部运动和局部按压作为疗效评定标准。经过平均 7.38± 0 .5 6次的治疗后 ,痊愈率是 5 0 % ,显效率是 31 .3% ,有效率是 1 5 .6 % ,无效率是 3.1 %。总有效率是 96 .9%。本临床观察发现 ,激光治疗棘上韧带和棘间韧带损伤具有有效率高、平均治疗次数少、见效快的特点 ,是治疗此类软组织运动创伤的较好方法之一。

New method of improving parts accuracy by adding heat balance support in selective laser sintering

In order to improve parts accuracy, a method of adding heat balance support （HBS） was proposed, and the detailed algorithm for generating HBS was developed. A number of experiments and a comparison between similar softwares, showed that the algorithm is efficient and feasible. Moreover, different features of riBS were studied for different kinds of materials, such as PS and nylon. The research findings indicate that automatically adding HBS can significantly improve the accuracy of the parts, and that the algorithm for generating HBS is efficient and precise.     

Position detection and vibration monitoring system using quad-cell optical beam power distribution

In this paper, we study the accuracy of an optical vibration sensing system using Gaussian beam analysis. The proposed optical system uses a He-Ne laser source whose Gaussian beam impinges on a quad-cell photodetector array. The normalized optical power for each cell is obtained through numerical simulation based on the well-known Gaussian beam optics formulation, as the beam scans the plane of the photodetectors due to vibration. The system detection principle lies upon finding a relationship between the power distribution of the quad-cell and the position of the beam centroid, which allows us to identify the characteristics of the vibration applied, such as direction, frequency and strength. The aspects of practical implementation and experimental limitations on the power distribution accuracy are discussed and the discrepancies with the theoretical results are presented.

Using Brillouin fiber-optic ring laser to provide base station with uplink optical carrier in a 10 GHz radio over fiber system

In this paper, a 10 GHz radio over fiber system is analyzed. The Brillouin fiber-optic ring laser is used in the
center station (CS) to suppress the optical carrier for the modulation depth enhancement. Simultaneously, the Stockes wave
induced by the Brillouin amplification injects and locks the Fabry-Perot (FP) laser to output a signal-mode optical source,
which works as the uplink optical carrier.
