无人机(UAV)产业自兴起以来在国内外快速发展,广泛应用于多个领域,但是有些不恰当的利用对公共安全和法律秩序构成了挑战。为完善高速铁路沿线的UAV安全管理立法,分析UAV安全管理立法现状;综述国内现有法规对UAV安全管理相关规定;探讨高速铁路沿线UAV安全管理立法及立法三要素内容。研究结果表明:高速铁路沿线无人机安全管理立法应具备无人机禁止飞行范围、监督管理部门和法律责任三要素;出台高速铁路安全相
通过对海绵常用监测设备进行实测对比,分析了影响数据准确性的原因,从设备适用性、设备量程、设备精度、设备安装条件、数据获取等方面阐述了影响设备选择的因素。对适合海绵城市监测的常用监测设备提出了选择建议,应考虑监测周期、数据获取便利性、成本等综合因素选择适合的监测设备。
本文采用连续流动分析法和4-氨基安替比林分光光度法分别测定水中的挥发酚含量,讨论两种检测方法的准确度、精密度及线性。结果表明两种方法测得结果、各项指标均符合标准要求,而连续流动分析法操作简单、受到干扰较小、无须接触对人体有毒有害的三氯甲烷,且能满足大批量的环境样品快速分析,极大地提升了当前环境监测实验分析的便捷性和安全性。
