Abstract: A multi-scale aggregation pattern analysis method for a complex traffic network is provided, which belongs to the field of the highway traffic network. Firstly, an adjacency matrix, a position attribute matrix, a distance weight matrix, a road grade matrix, and a time-phased traffic congestion degree matrix of a highway traffic network are calculated; secondly, a weight influence factor of the road network is incorporated based on a PageRank algorithm to determine order of critical nodes; finally, a two-dimensional decision diagram is drawn by two indicators: order of critical nodes and a shortest path distance. A new weighting matrix which accords with the actual situation of the road network is obtained by incorporating a position weight matrix, a distance weight matrix, a road grade weight matrix and a dynamic traffic congestion degree weight matrix based on a similarity matrix of the spectral clustering.

Abstract: Disclosed are a method and device for evaluating damage caused by secondary stress to a vacuum vessel, a terminal device, and a medium, to perform following steps: obtaining secondary stress of a vacuum vessel that passes a primary-stress failure evaluation; obtaining structural damage parameters of the vacuum vessel when determining, based on evaluation parameters for the primary-stress failure evaluation of the vacuum vessel and the obtained secondary stress, that the vacuum vessel meets a precondition for a progressive deformation; and determining, based on the obtained structural damage parameters, whether the vacuum vessel meeting the precondition for the progressive deformation experiences structural damage due to the progressive deformation. In this way, a vacuum vessel of a nuclear fusion reactor can be evaluated based on damage caused by the secondary stress.

Abstract: The body of a herbaceous plant, Cistanche tubulosa (Schenk.) Wight, is used to make a medicinal preparation containing phenylethanoid glycosides and comprising 10-70% of echinacoside by weigh of the preparation and 1-40% of acteoside by weight of the preparation. The medicinal preparation is used as an active ingredient of medicinal composition for use in prevention of senile dementia, and inhibition of aggregation of blood platelets.
