Effects of landscape fragmentation on floodplain fishes as revealed by species–habitat networks
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract How species interact with habitat patches is influenced primarily by habitat configuration (e.g., connectivity) and species’ functional traits. As levels of fragmentation increase, identifying the intricate connections between these components is crucial for biodiversity conservation.

Jianzhu Gangjiegou Jinzhan, 2010 目前组合"王"字形截面梁在钢结构建筑中经常用到,但对于其稳定计算现行钢结构规范还未有具体规定。本文通过将组合"王"字形截面梁的试验结果与参考文献[4]中的稳定计算方法得出的结果进行分析比较,得出试验的结果偏大,建议在稳定计算时对双力矩的数值进行适当的折减。

Jianzhu Gangjiegou Jinzhan, 2007 位于中国北京的中国国际贸易中心三期主塔楼高330米,包括一座五星级酒店和甲级写字楼。建筑物的高度和北京的高抗震烈度设计对于结构设计师都是一个挑战,特别是考虑到中国规范中各项严格的要求。在结构设计过程中,各种结构类型及不同材料的使用都经过讨论研究。最终的结构体系是一个组合支撑框架核心筒和组合周边刚性框架筒,在机电层再辅以伸臂桁架连接两个筒。由于塔楼外立面宽度逐渐收小,结构上采用了三层腰桁架,而在腰桁架之间柱子的数量逐渐减少。塔楼的底部是八层高带转换桁架的V型柱 ...
