唐诗《逢雪宿芙蓉山主人》四种英译文的经验功能分析

从韩礼德的经验功能的观点出发,对唐朝诗人刘长卿的《逢雪宿芙蓉山主人》一诗及其四种英译文进行过程类型、参与者和环境成分分析。结果显示:功能语言学的经验功能分析框架可以帮助我们以崭新的视角,解决古诗英译过程中理解和表达的问题。恰当的选择契合原诗的过程类型或者在不同过程类型中选择最有利表现原诗的过程类型都值得古诗英译标准研究的关注。     

肌肉收缩张力与收缩速度基本关系阐释

肌肉收缩张力与收缩速度的关系是肌肉力学中最重要的关系。Hill方程描述的“张力愈大 ,收缩速度愈小”和通常认为的“肌肉力量愈大 ,收缩速度愈大”恰好相反。本文给出这一悖论的阐释 ,以正确指导运动员进行肌肉力量训练     

National differences in personality: Greece and England

A comparative study was carried out on Greek and English samples, using the Eysenck Personality Questionnaire. Factor analysis of intercorrelations between items showed that very similar factors emerged in the two national groups, suggesting that the structure of personality in both was sufficiently similar to carry out comparative studies. External validation supported this conclusion; normal, schizophrenic, neurotic, and criminal groups showed patterns of scores similar to those previously observed in England. In both countries it was found that men scored more highly on P and E, women on N and L. Differences in loadings were found on certain items, and these were shown to be explicable in terms of known national differences in habits and mores.     

矮杨梅的光合作用及耐荫性研究

对贵州矮杨梅叶片叶绿体希尔反应活力和叶绿素含量的测定,并对其光合作用特征进行了初步的探讨。其结果表明：矮杨梅为耐荫植物,对六盘水市杨梅市杨梅乡野生矮杨梅植物种群生物量测定表明：矮杨梅生物量主要在地下部位积累,鲜重的根冠比（R／T）范围2．89-32．8,平均10．8;干重的根冠比平均为9．7。     

山坡地农业开发中的水土资源保育问题探讨

该文针对南方,特别是福建山坡地开发中造成的水土流失与土壤退化等生态环境问题,在野外调查与试验研究的基础上,系统分析了近年来山地果园开发规模、现状以及开发中存在的系列水土资源保育等生态问题;揭示了山地果园水土流失发生发展的机理;明确了山地果园开发中需要注意的关键时期与关键地形部位;分析了果树早衰的原因.以生态经济学与可持续发展为理论,以山地水土资源合理开发利用为基础,提出了科学规划,坚持适地适种,提高建园质量,加强幼园管理,推行山地水土资源保育新技术,增加地面覆盖,控制水土流失,建设生态果园的可持续发展综合治理体系和对策.     

阿奇博尔德.希尔的神经生理学贡献——学科历史功绩及启示

英国生理学家阿奇博尔德·希尔长期从事神经生理学研究并做出了重要贡献。他首次发现神经受刺激后的产热现象并对此进行了深入探讨。他提出高度概括的电兴奋与适应的成功理论,对电生理学的发展产生了积极影响。本文对希尔在神经生理学领：战的工作和贡献进行历史性回顾,并揭示其现实的深刻启示,以期为今后的科学研究提供借鉴。     

打造五陵原文化圈 提高咸阳地域竞争力

对五陵原文化遗存的旅游现状进行了分析,建议组织专门的研究和开发机构打造五陵原文化圈,依托区域优势打造名牌旅游景点、航空港旅游中心等,以提高咸阳地域竞争力。     

隧道前方地震预报法在万寿山隧道超前地质预报中的应用

爆破激发的地震波在围岩中传播时,部分地震波会被反射。隧道前方地震预报法用TSP203 Plus接收器将反射的地震波进行收集并转化为数据,利用TSPwin软件对数据进行处理,获得前方地层的地质力学参数,评估隧道掌子面前方围岩与地层情况。该方法具有预报距离远、精度高,对施工干扰小等优点。     

Comments on ＂How to repair the Hill cipher＂

A modification of the Hill cipher algorithm was recently proposed by Ismail et al.（2006）, who claimed that their new scheme could offer more security than the original one due to an extra non-linearity layer introduced via an elaborated key generation mechanism. That mechanism produces one different encryption key for each one of the plaintext blocks. Nevertheless, we show in this paper that their method still has severe security flaws whose weaknesses are essentially the same as that already found in the original Hill cipher scheme.
