闽南—台湾浅滩上升流区发光细菌的生态分布与种类组成

研究了闽南-台湾浅滩上升流区海洋发光细菌的生态分布与种类组成,结果表明:该海区海水中发光细菌的数量波动范围为0.5～12.5CFU/ml,占总菌数的0.49％～14.67％,对所采得的共108个水样进行了发光菌数分析,其中有74个水样可检出发光细菌,占总水样数的68.7％,发光细菌在沉积物中的数量波动在0.188×10~3～2.25×10~3CFU/g之间,占总菌数的0.67％～9.44％,发光细菌由明亮发光细菌(Photobacterium phosphoreum)、哈维氏发光细菌(Lu-cibacterium harveyi)、曼德帕母发光细菌(Photobacterium mandapamensis)和费氏发光细菌(Vibriofischeri)四个种组成,以P.phosphoreum为优势种,同时讨论了发光细菌的生态分布与环境因子的关系及其在上升流指示中的重要作用。     

岩体特性对围岩与结构动力相互作用影响

通过研究岩石特性,进一步对围岩与结构动力耦合机理进行分析。爆炸荷载原型实验研究困难较大,因此应用ANSYS/LS-DYNA非线性显式动力有限元程序和流固耦合计算方法,对垂直爆炸不同岩石类别、不同跨度地下拱形结构进行数值模拟,得到了岩石类别对于不同跨度结构影响的不同规律。研究表明:岩石硬度越大,拱顶动力相互作用显著增大,远距离爆炸对大跨硬岩结构拱肩和拱脚产生明显的反复拉压作用;岩石越软,跨度越小,近距离爆炸对整个结构动力相互作用影响越大。

建立了装有静止无功补偿器和静止同步补偿器的单机无穷大电力系统的扩展Phillips—Heffron模型,并基于该模型,通过实例仿真验证了静止无功补偿器和静止同步补偿器多个控制器之间存在着负交互影响的可能性。该结论将为多个多控制功能的FACTS控制器的协调设计提供基础。     

Issues and prospects of belowground ecology with special reference to global climate change

The theory of ecology is based on over 100 a of research and investigation, all centered on aboveground patterns and processes. However, as contemporary ecologists are increasingly acknowledging, belowground structures, functions, and processes are some of the most poorly understood areas in ecology. This lack of understanding of belowground ecological processes seriously restricts the advance of global change research. The interdisciplinary field of belowground ecology began to flourish in the 1990s, along with the expansion of global change research, and quickly gained momentum. Belowground ecology aims to investigate belowground structures, functions, and processes, as well as their relationships with corresponding aboveground features, emphasizing the responses of belowground systems under global change conditions. Key research areas include root ecology, belowground animals, and soil microorganisms. This review summarizes and analyzes the relationships between aboveand belowground ecosystems, root ecology, root biogeography, belowground biodiversity, as well as research areas with particular challenges and progress. This commentary emphasizes certain theoretical issues concerning the responses of belowground processes to global change, and concludes that belowground ecology is a critical research priority in the 21st century.     

Study on response of ecosystem to the East Asian monsoon in eastern China using LAI data derived from remote sensing information

Based on the leaf area index (LAI) data derived from remote sensing information and eco-climate data, the responses of regional ecosystem variations in seasonal and interannual scales to the East Asian monsoon are studied. It is found that the vegetation ecosystems of eastern China are remarkably correlated with the East Asian monsoon in seasonal and interannual scales. In the seasonal timescale, the obvious variations of the vegetation ecosystems occur with the development of the East Asian monsoon from the south in the spring to the north in the autumn. In the interannual scale, high LAI appears in the strong East Asian monsoon year, whereas low LAI is related to the weak East Asian monsoon year. These further lead to the characteristic of "monsoon-driven ecosystem" in the eastern China monsoon region, which can be revealed by LAI.

浙江的道教与戏剧

从浙江道教与戏剧的历史及现状入手,以田野调查所获的第一手资料为依据,客观地论述道教仪式与戏剧的密切关系:戏剧不仅在起源方面离不开道教,是道教仪式戏剧化、舞台化、民俗化的结果,而且以道教仪式为载体、与内坛法事互补互动、有机统一,赖道教仪式以生存,并从道教仪式中获得大量观众和市场,以求得自身的不断壮大和发展。
