In the context of global warming and intensified human activities,glacier instability in plateau regions has increased,and glacier debris flows have become active,which poses a significant threat to the lives and property of people and socioeconomic *** mass movement process of glacier debris flows is extremely complex,so this paper uses the 2018 Sedongpu glacier debris flow event on the Qinghai-Tibet Plateau as an example and applies a numerical simulation method to invert the whole process of mass *** view of the interaction between phases in the process of motion,we use the fluid-solid coupling method to describe the mass *** granular-flow model and drift-flux model are employed in FLOW3D software to study the mass movement process of glacier debris flows and explore their dynamic *** results indicate that the glacier debris flow lasted for 700 s,and the movement process was roughly divided into four stages,including initiation,scraping,surging and deposition;the depositional characteristics calculated by the fluid-solid coupling model are consistent with the actual survey results and have good reliability;strong erosion occurs during the mass movement,the clear volume amplification effect,and the first wave climbs 17.8 m across the *** fluid-solid coupling method can better simulate glacier debris flows in plateau regions,which is helpful for the study of the mechanism and dynamic characteristics of such disasters.

城市管理综合执法,是以相对集中行政处罚权为主要内容的,以实现行政规范、运转协调、公正透明、廉洁高效、权责明确、监督有效、保障有力为目标的行政执法。几年来,兰州市城市管理综合执法进展顺利,取得了一定的实效,但也存在着对行政综合执法认识上的不足;执法理念上偏离;执法机制上混乱和执法规范上缺失;执法方式简单化、运动化、趋利化等问题。为此,加强行政综合执法改革理论研究;改造职权分配体制,注重发挥市场、社会调整机能;坚持依法执法,加强行政执法立法;树立执法为民的思想观念,提高执法人员素质是当务之急。

已有的用户角色研究中,不少学者定义了角色的数目和特征,对特定数据集取得了较好的效果,但存在的两个问题:1)通用性较差,若更换数据集必须重新分析;2)现实世界中用户行为和关系纷繁复杂,用户角色多种多样,难以通过人为的定义去描述和识别.因此,本文基于张量分解模型提出了一种用户角色发现算法,它不仅能自动设定角色数量,而且能反映角色在指定时间段的行为特征.进一步将用户角色延伸到社团角色,提出基于社团角色距离和节点重叠的社团演化分析方法.实验结果表明,识别出的用户角色其行为特征与实际情况吻合,提出的社团演化分析方法其效果也高于对比算法.
