针对区块链游戏生态的复杂性,提出一种基于时序有向加权网络的新型角色识别方法。该方法首先设计了节点投票算法ChainVoteRank以识别出关键基础角色,然后结合多特征融合的层次聚类算法挖掘潜在的隐蔽角色。以play-to-earn(P2E)模式区块链游戏Axie Infinity为对象进行研究,结果表明该P2E模式区块链游戏生态中存在6种基本角色:劳工、正常玩家、经理、繁育商、交易商和机构组织。相较于传统角色识别方法,该方法不仅可以更好地识别出区块链游戏生态中的主要用户角色,而且还揭示了P2E模式区块链游戏生态的角色演化过程、不同阶段中各角色发挥的作用,以及P2E生态日益严重的贫富差距。

Inspired by previous resistance models for porous media, a resistance expression of gas migration within coal seams based on the ideal matchstick geometry, combined with the Darcy equation and the modified Poiseuille equation is proposed. The resistance to gas migration is generally dynamic because of the variations in adsorption swelling and matrix shrinkage. Due to the limitations of experimental conditions,only a theoretical expression of resistance to gas migration in coal is deduced, and the impacts of tortuosity, effective stress and pore pressure on the resistance are then considered. To validate the proposed expression, previous data from other researchers are adopted for the history matching exercise, and the agreement between the two is good.

基于VOF方法追踪水气界面,利用不可压缩流体连续方程和运动方程对流体进行描述,通过嵌套网格技术建立三维数值水槽,湍流采用RNG k–ε模型,泥沙运动基于Van Rijn方法。基于验证后的数值水槽模型,开展水流作用下高桩承台结构局部水动力和冲刷规律研究,讨论不同来流条件下桩基桩周流场分布、泥沙输运和床面局部冲刷特征。结果表明,桩基冲刷特征受冲刷时间、流速、水位、水流攻角等来流条件的影响,同时也受桩间距的影响。当流速较小时,高桩承台桩基各桩之间相互作用较小,泥沙冲淤形态彼此独立,与单桩冲刷特征相似。流速较大时,前桩对后桩出现较为明显的遮蔽作用,前桩水流涡旋影响后桩,后桩周围流速明显降低,此时泥沙冲刷坑彼此相连构成群桩整体冲刷坑,且在最后排桩桩间形成条状冲刷坑,冲刷深度最大。
