论爱默生其人其诗

Ralph Waldo Emerson, born in 19th century's America, is most famous for his transcendental ideas and writings. He was deeply influenced by European Romanticism in his thirties and formed an informal Transcendental Club with people of like minds. His thought is often considered the core of Transcendentalism. "Nature" is the fundamental document of his philosophy and an embodiment of his transcendental attitude towards the phenomenal world. He also wrote some other brilliant essays such as "The American Scholar", "Self-Reliance", "The Over-Soul" and "The Poet", etc, all of which established his indisputable position in the history of culture, especially in the American Culture where he is regarded as the one who, in literally terms at least, really put America on map. But considering Emerson's writings without significant emphasis on his verse would be a great loss. Emerson wrote poetry from the time he was a boy to nearly the end of his life. These poems are essential for understanding him and his transcendental theories and are receiving more extensive representation in anthologies while significant critical analyses are emerging though some modern readers and scholars tend to view his poetry as secondary to the "essential" Emerson. In view of the above, this paper supposes to introduce Emerson's views on poets and poems and then analyze some of his famous poems in the order of 'Emerson as a Poet', 'Emerson's Views on Poets and Poems' and 'Emerson's Poems' with the third one as the focus of this paper. The purpose of this paper is to try to make the comprehension on Emerson and his abstract transcendental theories more complete and thorough by emphasizing his contribution in the poetic field.     

复杂装备维修训练通用仿真系统

提出了一个用于复杂装备维修训练的桌面虚拟系统,可以练习某些特定组件的维修拆卸.利用动态链接库实现了系统模块化的软件体系结构,保证了数据的封装和模块化.通过用户化过程设置了用于拆卸顺序规划和VR环境3D模型的数据库,在友好的用户界面的引导之下,用户通过在虚拟环境中的漫游和实时更新的维修信息的帮助下了解全部维修过程.系统能够在生成合理的拆卸顺序和确定配件方面提供智能辅助,而且原型系统提供了针对CAD模型文件的数据接口,系统可以被看作是一个"外壳".通过用户化工作将3D模型转化成系统可以接受的VRML格式,这样就可以非常容易地针对不同的维修任务建立虚拟环境.与沉浸式和增强型VR系统相比,这套桌面VR原型系统的硬件需求不会使训练任务局限于某个训练房间或特定的使用者.对于维修训练来说是一个便携、经济的解决方案.

舰艇多目标威胁评估及可视化方法综合研究

对舰艇多目标威胁度的评估是反舰导弹突防任务指挥中首要解决的问题之一,而评估结果的可视化有助于作战指挥人员直观地区分威胁目标的轻重缓急,从而为反舰导弹的突防迅速做出决策。提出了一种舰艇多目标威胁度评估及可视化的综合方法。首先,运用灰色关联度分析理论对影响舰艇多目标威胁度的属性因子之间的关联度进行了评估,并建立评估模型。然后,利用SuperMap GIS软件进行了作战过程的二维态势显示研究,通过面向用户的类库设计开发出了实用的评估过程可视化软件平台。

极端事件与影响评价:赞比亚干旱对其社会经济之影响(英文)

Objective--To investigate the effects of extreme events such as floods and droughts on social and economic activities in Zambia. Methods--The annual daily rainfall for stations, which have complete 40 years （1960-2000） time series of daily rainfall, is assigned to one of the five classes. class 1 （0-0.5 ram）, class 2 （0.5-5 mm）, class 3 （5-10 mm）, class 4 （10-25 ram） and class 5 〉25 ram）. Class 1 refers to dry days or nearly dry days where as classes 2 to 5 refer to wet days. Class 5 refers to high intensity rainfall days. The daily rainfall for the three Agro-Ecological zones is computed by averaging the daily rainfall of all the meteorological stations falling in each zone. Simple linear regression is performed to establish trends for the variables namely （i） annual number of days in each of classes from two to five, （ii） annual number of wet days and （iii） annual rainfall amount, for individual stations as well as for the three eco-climate zones. The student＇s t -tests are carried out to determine the significance of trends. The level of significance used in the trend analysis is set to 0.10. Results--This paper dwells on the drought trend in Zambia and its social and economic ramifications as it is exposed to the crises, stress and shocks arising from the fluctuating weather conditions. The food system in Zambia which has developed since the colonial period and has persisted even after the attain- ment of political independence in 1964 is increasingly becoming vulnerable to environmental shocks be- cause of the climate change and variability as maize the main staple food is more susceptible to extreme weather events as shown in this analysis of drought events. Trends for annual number of days in clas- ses three and four for all analyzed data are found to be negative indicating that days with rainfall intensity of 5-25 mm are decreasing at each of analyzed individual station and also in the three agro-ecological zones. Annual numbers of days of low intensity rainfall （0.5~-10 mm） in zone 1 are increasing pointing drier conditions. Annual number of days of high intensity rainfall （〉25 mm） are increasing in zones 2 and 3 indicating flooding conditions. Conclusion--Results have shown that drought can have dramatic deleterious effects on a country＇s socioeconomic, ecological as well as having some political ramifications as it affects stable flow of finances to government projects. For a small and intermediate economy like Zambia＇ s, it is very susceptible to draught episodes, because it is driven hy a large agricultural sector. That is, food availability and prices, employment, access to imports, government expenditures, availability of social services, and credit sources are all affected by drought.

中世纪的科学及其与基督教的关系

近代科学诞生于基督教欧洲不是突发的或偶然的,资本主义的兴起对近代科学的出现固然起决定性作用,但更有其深厚的传统文化基础作先导。无疑,基督教文化充当了承上启下的桥梁作用,它上承希腊哲学,下启近代科学,它作为中间环节,在诞生时吸收和同化了希腊哲学,在中世纪启蒙了西方的理性,孕育了近代科学的胚胎。本文将对此论点展开论述。
