在位处我国中部的湖北省,选取典型农业型村镇开展了为期1年的生活垃圾采样,分析其物理组分、理化性质及重金属含量。研究发现:中部典型农业型村镇生活垃圾中灰土类含量最大,其次是厨余类;春冬季,生活垃圾的含水率、湿基低位热值和VS含量略高于夏秋季,容重的变化规律恰好相反;生活垃圾中重金属Cd和Cr超标的现象较严重,存在污染土壤的风险。相关性分析发现,重金属Cd和Cr含量与垃圾中砖瓦陶瓷类、金属类含量呈显著正相关。

Group data sharing enables information sharing between multiple parties for cooperative purposes. However, the existing schemes only consider scenarios in which all parties in the same organization want to share data. Achieving secure data sharing between users of different groups is also a relevant research issue. In this paper, we propose a blockchain-based data sharing scheme for multiple groups with anonymity and traceability. Owing to the consortium blockchain technique, any user in the system can easily verify the validity of the shared data without interacting with a third-party auditor. Additionally, the proposed scheme can not only enable data sharing between different groups with enhanced security anonymously but also achieve traceability and non-frameability.

ymmetry of the world trade network provides a novel perspective to understand the world-wide trading system. However, symmetry in the world trade network （WTN） has been rarely studied so far. In this paper, the authors systematically explore the symmetry in WTN. The authors construct WTN in 2005 and explore the size and structure of its automorphism group, through which the authors find that WTN is symmetric, particularly, locally symmetric to a certain degree. Furthermore, the authors work out the symmetric motifs of WTN and investigate the structure and function of the symmetric motifs, coming to the conclusion that local symmetry will have great effect on the stability of the WTN and that continuous symmetry-breakings will generate complexity and diversity of the trade network. Finally, utilizing the local symmetry of the network, the authors work out the quotient of WTN, which is the structural skeleton dominating stability and evolution of WTN.
