精细化治理空气污染正成为改善城市环境品质的重要方向,街道绿化与街道PM_(2.5)浓度相关性的研究有助于为城市设计与更新提供科学依据。然而,街道绿化对空气质量的影响是复杂的,仍需进一步研究。以武汉街区为研究对象,通过Python软件爬取百度地图街景图像,利用视觉图像语义分割软件获得街道绿视率(GVI)并将其作为量化街道绿化的指标。基于移动观测数据,采用相关性分析探究GVI对PM_(2.5)浓度的影响。研究表明,GVI与街道PM_(2.5)浓度整体上呈正相关关系,上下午存在差异性:与上午PM_(2.5)浓度的关系并不明显,但与下午PM_(2.5)浓度呈显著正相关关系(P<0.05);不同缓冲区GVI呈现相似的影响趋势,但实测街道GVI对PM_(2.5)浓度的影响效果相比于周边道路GVI更强,影响的缓冲区也更大。

黄斑裂孔主流术式玻璃体切除联合内界膜剥除及玻璃体腔气体填充术对患者术后体位有所要求,如面朝下体位(face-down position,FDP)等特殊体位。对术后体位的选择及监测方式的研究有助于患者提高依从性,增加正确体位时间,减少不良体位时间。如何在保证黄斑裂孔闭合率的前提下减少FDP时间或其他可代替FDP的体位与术式是研究的重点。裂孔>400μm的特发性黄斑裂孔患者术后严格保持一定时间的FDP是术后标准的护理过程。裂孔<400μm时术后非仰卧位与FDP相比对裂孔闭合率的影响尚无明确结论。目前FDP体位监测仪包括Maculog电子设备、连接耳机的弧形夹具头位监测仪、头部固定式传感器、带传感器的粘贴式眼罩等;对于非仰卧位监测有滚球型传感器与倾斜开关式头位监测装置、可实时视听反馈的可穿戴无线定位传感器等,可对患者术后体位起到提醒与记录作用。一些研究采用术中及术后OCT检查指导FDP的持续时间。

为优化支架固定馆藏人物俑文物的抗震效果,选取不同尺寸和体态的典型地震易损人物俑文物复制品(武士俑和唐三彩人物俑),开展文物复制品-优化组合措施(支架和卡固件)抗震系统振动台试验,获得影响文物复制品运动状态的关键优化参数、文物复制品与支架相互作用规律,并检验组合措施对较大体积人物俑文物的抗震固定效果。建立文物复制品-组合措施相互作用系统数值分析模型,通过参数分析,获得支架与文物间安装缝隙、在安装缝隙内填充不同种类隔震垫对文物动力响应的影响、文物复制品与固定措施相互作用规律及采用独立支架/组合措施有效固定人物俑的最小支架尺寸,为兼顾安全性及最小干预原则的固定措施优化设计提供必要依据。结果表明:相比独立支架,组合措施能够有效降低人物俑文物动力响应,有效提高固定效果;为保证人物俑文物安全,建议支架与文物间安装缝隙不大于5 mm;在缝隙中填充橡胶垫及硅胶垫可使文物与支架间相互作用力降低50%~75%,有效防止文物局部损伤;当人物俑文物体型超过一定限值,独立支架不再适用,建议选择支架和随形卡固件组合措施。
