后张法预应力混凝土自复位墙是一种有效的可恢复功能结构。虽然自复位墙自身在地震中损伤较小,但其与周边构件的变形不协调可使结构损伤严重。为控制结构层面的损伤,设计了1个框架-自复位墙结构,对自复位墙底、梁柱节点、墙梁节点、墙-基础连接、柱-基础连接以及墙-板连接开展损伤控制设计,并对设计的结构进行足尺振动台试验。结构共经历了39次不同设计工况下不同烈度的地震激励,峰值加速度最大达1.0g,位移角最大达3.3%。对结构在历次地震作用下整体、局部构件和节点的损伤发展进行全过程定量分析,结果表明:自复位墙-开槽梁结构在地震作用下的损伤能够得到有效控制,其中多遇、设防地震作用下结构基本无损伤,罕遇地震作用下墙底损伤仅限角部剥落且面积仅为400 cm2,楼板有开裂且裂缝最大仅为1.2 mm,梁端剥落可忽略;自复位墙-开槽梁结构可使整个结构在不同设计位移角下实现多遇、设防地震不坏,罕遇地震小修甚至不修的抗震性能目标;设计的连接方式解决了结构中构件之间的变形不协调问题,提高了自复位墙结构层面的可修复性。

作者： Amelia henry Rice Breeding Innovations Department International Rice Research InstituteLos BanosLagunaPhilippines

Rice ratoon cropping,or the cultivation of tillers that have regrown from existing stem nodes of a harvested crop,is currently a hot topic in agriculture,and record-high ratoon crop yields have been achieved in China(Xu et al.,2021).Although rice ratoon cropping is most appropriate for certain agro-ecosystems with a suitable climate and cropping schedule,it is a promising strategy to simultaneously increase productivity while reducing inputs and *** ratoon cropping may thereby contribute to global food security and agro-ecosystem sustainability.

2205不锈钢作为第二代不锈钢已被广泛应用于耐蚀性高的石油管道、海洋平台等工业领域。定向凝固能够揭示不锈钢的凝固过程，并为研究凝固过程中溶质偏析提供基础。微区分析方法的种类可分为波谱及能谱两类，本文分别以电子探针（EPMA）配备的波谱仪（WDS）及能谱仪（EDS）对2205不锈钢材料固液界面的溶质偏析进行分析及对比，以研究不同仪器对于微观溶质偏析结果准确性的差异。结果表明，相对于能谱仪，电子探针配备的波谱仪能够更加直观地反映出固液界面元素的变化规律，其测定结果具有更高的精确性。

[1]时过境迁,我居住在更接近天下那些我最向往的地方,生活在更接近那些我最向往的历史时代。我的住地就像天文学家在夜间观测到的许多天体一样遥远。我们惯于想象在星系中某个遥远的天国的一角,在仙后星座的背后,有一些罕见的怡人之处,远离喧哗与骚动。我发现,我的房子实际上就位于宇宙间这样一个静的、但却永远新鲜、不染尘垢的地方。
