举重若"轻"——当代轻型建构的适应生成之路

"轻"在当代建构发展中是一个具有深远意义的话题.通过对轻型建构理念溯源与概念解析,从材料改良、力学探索与环境响应三个方面对轻型建构在当代的适应发展进行了讨论,总结出当下轻型建构组织生成的三种特点.阐释了轻型建构表象之后的仿生学与结构学逻辑.指出面向环境调控的轻型建构作为核心议题将借助智能工具、自组建造等前沿技术成为解决能源与环境危机的重要手段.

Xanthium Suppression Under Maize||Sunflower Intercropping System

Weed control is one of the major constraint factors in crop production around the world. Field experiments were conducted during 2008-2009 under intercropping systems involving alfalfa （Medicago sativa L.）, sweet potato （lpomoea batatas [L.] Lain.）, peanut （Arachis hypogaea L.）, and sunflower （Helianthus annuus L.） in maize （Zea mays L.） without any weeds control methods taken. The results demonstrate that maizellsunflower is most effective on weed suppression and that it also has a more competitively inhibitory effect on Xanthium compared with the other patterns by evaluating the Xanthium density and dry weight under different intercropping systems with maize. Maizellpeanut, maizellalfalfa and maizel]sweet potato intercrops have no apparent inhibitory effect on weeds. To further investigate the effect of maize]lsunflower on weed control, indoor pot experiments were conducted by determining the effect of extractions on germination rate （GR）, root vigor, MDA （malondialdehyde）, SOD （superoxide dismutase） and POD （peroxidase） content of Xanthium. The results better prove that maizellsunflower extractions have more significant inhibitory effect on GR and young root vigor of Xanthium than maize monocrop extractions.

手臂部烧伤整形植皮术后的综合康复护理

目的探究手臂部烧伤整形植皮患者的综合康复护理方法及效果。方法采用回顾性分析方法,选取于2018年8月份至2019年8月份在医院中进行手臂部烧伤整形植皮治疗的患者64例,均采用压迫疗法、温水浸浴、局部按摩、肌力训练、康复指导对其进行综合康复护理3个月,并比较患者在术前与康复护理3个月后的MHQ评分、DASH评分、VAS评分以及护理满意度。结果康复护理3个月后,患者的手部功能评分低于术前(P<0.05)。与术前比较,康复护理3个月后患者的DASH、VAS评分均降低(均P<0.01)。术前、康复护理3个月后的护理满意度分别为87.50%、96.88%,康复护理3个月后的护理满意度高于术前(P<0.05)。结论多种方法形成的综合康复护理方法可以促进上肢烧伤后植皮术患者上肢功能的恢复,减轻术后疼痛,值得在患者护理工作中大力推广使用。
