记录和理解外界压力刺激对于人与周围环境交互的研究和智能机器人的开发具有重要意义.现有的压力传感设备多为刚性结构难以自然贴附于物体表面,且低密度传感单元使得物体压力特征信息的获取受到限制,一种可适形、全覆盖、高密度的压力传感与分析系统亟待研究.本文采用湿法纺丝工艺连续化制备了芯层为混纺导电芯材,包层为碳纳米管掺杂的聚氨酯的核壳结构压感纤维,通过缝纫、刺绣方式在织物表面构筑经纬结构的交叉点压力传感阵列.结合阵列数据采集实时捕获压力图谱帧,基于深度学习卷积神经网络驱动的算法模型,实现了物体轮廓识别垫对环境物体的轮廓精准分类识别.该识别系统准确率高达99.4%,证明了其在提取物体的压力信息和揭示物体的形态特征的应用潜能.

Ambient air quality trends and driving factor analysis in Beijing, 1983–2007

Journal of Environmental Sciences 2011年第12期23卷 2019-2028页

作者： ju Zhang Zhiyun ouyang Hong Miao Xiaoke Wang State Key Laboratory of Urban and Regional Ecology Research Center for Eco-Environmental Sciences Chinese Academy of Sciences Beijing 100085 China

The rapid development in Beijing, the capital of China, has resulted in serious air pollution problems. Meanwhile great efforts have been made to improve the air quality, especially since 1998. The variation in air quality under the interaction of pollution and control in this mega city has attracted much attention. We analyzed the changes in ambient air quality in Beijing since the 1980’s using the Daniel trend test based on data from long-term monitoring stations. The results showed that different pollutants displayed three trends： a decreasing trend, an increasing trend and a flat trend. SO2, dustfall, B[a]P, NO2 and PM10 fit decreasing trend pattern, while NOx showed an increasing trend, and CO, ozone pollution, total suspended particulate （TSP）, as well as Pb fit the flat trend. The cause of the general air pollution in Beijing has changed from being predominantly related to coal burning to mixed traffic exhaust and coal burning related pollution. Seasonally, the pollution level is typically higher during the heating season from November to the following March. The interaction between pollution sources change and implementation of air pollution control measures was the main driving factor that caused the variation in air quality. Changes of industrial structure and improved energy effciency, the use of clean energy and preferred use of clean coal, reduction in pollution sources, and implementation of advanced environmental standards have all contributed to the reduction in air pollution, particularly since 1998.

为了更好地解释落后或欠发达地区招商引资与环境保护“两难困境”产生的原因,通过对基于FCVL模型框架分析环境政策、企业区位变化以及环境污染的内在传导机制的分析,从微观角度较详细地刻画了异质性企业的区位转移活动,同时分析了在合作与非合作的环境规制政策情况下,相应的均衡区位的形成以及污染量的显性解,为进一步进行实证研究提供了直接的理论支撑。对于贸易成本这一环境污染区域传导机制中的关键因素,通过对2010—2018年中国工业制造业38个行业动态面板模型的广义矩估计。研究表明,企业拥有的总资本大小对环境规制具有直接正向的影响,又能够通过单位产品产生的污染量、消费者价格指数和总资本大小的中介效应间接影响环境规制。实证研究表明,在较高的贸易自由度下非合作的环境规制会增加总污染量,合作的环境规制可以降低总污染量。
