农村环境治理现代化是中国式现代化的重要组成部分。我国农村环境治理面临“共同生态利益”维护的共识未形成、多元主体协同的互信机制不健全、平台化治理数据安全保障不充分等诸多制约因素,需要区块链技术予以赋能和化解。区块链的去中心化和集体维护优势,能够实现农村环境治理的规范有序和治理主体的多元互信,为我国农村环境治理构建全新的理论架构、技术思路和价值基础。区块链应用于农村环境治理也存在诸多挑战,包括区块链去中心化对农村环境治理公共性维护的挑战、区块链工具理性对农村环境治理中权利保障的挑战、区块链快速迭代对农村环境治理规则体系的挑战等。有必要坚持农村环境治理公共性优先的价值共识,构建技术治理与法律治理协同的权力限制与权利保障新架构,同时不断完善农村环境治理中区块链风险的技术规制制度。

为了有效分离软锰矿浸出液的镍离子,研究采用离子印迹技术,以壳聚糖为基体,制备了镍印迹壳聚糖珠体(Ni2+-imprinted Chitosan Beads, Ni-CTS)。采用傅里叶变换红外光谱(Fourier Transform Infrared Spectroscopy, FT-IR)对Ni-CTS进行了表征,考察了不同锰离子质量浓度背景及实际软锰矿浸出液中Ni-CTS对镍离子的选择性分离效果,以乙二胺四乙酸二钠(Ethylene Diamine Tetra-acetic Acid, EDTA)为解吸液对吸附剂的再生性能进行了研究。试验结果显示:在高质量浓度锰离子背景下,Ni-CTS对镍离子显示了较高的选择性,且先被吸附的锰离子会被后面吸附的镍离子取代,在Ni-CTS上存在对镍离子特异性吸附的活性位点。经过5次再生试验后,Ni-CTS对镍离子吸附质量比约为12.1 mg/g,仍表现出良好的吸附性能。在实际软锰矿浸出液中,吸附反应后浸出液中的锰镍质量浓度的比值由3 020提高到了8 635。

多层复合材料筒状结构的残余应力可造成内部分层、结构失稳等,有必要结合理论和实验等研究其内部应力形成机制。基于各向异性线弹性本构和平面应力假设,建立了温度载荷作用下多层复合材料筒状结构内部应力的预测模型,并通过有限元仿真和热膨胀变形测试对模型有效性进行了校核和验证。结果表明:筒状结构环向的热膨胀变形从内层到外层逐渐增大,其中内层附近环向热膨胀系数低于面内热膨胀系数、外层附近环向热膨胀系数则高于面内热膨胀系数。在此基础上,结合模型理论分析揭示了层间应力对多层复合材料筒状结构的热膨胀变形行为的影响机制。在筒状结构形式下,温度加载引起的层间应力由一个涉及热膨胀系数和弹性参数的热力耦合项决定;由于多层复合材料面内与面外热膨胀系数存在差异,该应力耦合项不为0,从而在温度加载下形成了层间应力并影响了环向膨胀变形行为。基于上述认识,提出了调控多层复合材料筒状结构层间应力的有效措施。本文对揭示多层复合材料筒状结构的层间开裂物理机制、优化其热力匹配设计等具有重要意义。

The tile-based multiplayer game Mahjong is widely played in Asia and has also become increasingly popular worldwide. Face-to-face or online, each player begins with a hand of 13 tiles and players draw and discard tiles in turn until they complete a winning hand. An important notion in Mahjong is the deficiency number(*** number in Japanese Mahjong) of a hand, which estimates how many tile changes are necessary to complete the hand into a winning hand. The deficiency number plays an essential role in major decision-making tasks such as selecting a tile to discard. This paper proposes a fast algorithm for computing the deficiency number of a Mahjong hand. Compared with the baseline algorithm, the new algorithm is usually 100 times faster and, more importantly,respects the agent's knowledge about available tiles. The algorithm can be used as a basic procedure in all Mahjong variants by both rule-based and machine learning-based Mahjong AI.
