Beryllium powders with the same particle size and various contents of beo were prepared by pre - sintering - acid washing processes initiatively and the influence of beo alone on o mys of beryllium was observed and some new results have been obtained - compared with the content of beo, the distribution of beo in beryllium has more critical influence on mys ; finely dispersed beo along the grain boundaries and in the matrix results in the dispersion strengthening of beryllium matrix and thereby the higher mys value ; on the contrary, the coarser beo particles clustering on the grain boundaries results in negative influence on o mys
開創性地用預燒結? ?酸洗工藝制備了相同粒度、不同beo含量的鈹粉,從而開展了beo含量單獨對鈹材_ ( mys )影響的研究,得出一些新的結果:與beo含量相比, beo在鈹中的分佈狀態對_ ( mys )的影響更大。沿晶界、晶內彌散分佈的較細小beo對基體鈹有彌散強化作用,使_ ( mys )即較高;如果beo較粗大地成簇狀聚集在晶界,反而對_ ( mys )有不良的影響。Comprehensive cellular responses was found in human amnion fl cells following exposure to low concentration of mnng, such as the lowering of dna replication fidelity resulted from alteration of dna polymerase profile ; activation of a lot of transcription factors, such as api, creb, nf - kb etc ; clustering of egfr ( epidermal growth factor receptor ) and tnfr ( tumor necrosis factor receptor ) and activation of camp - pka - creb and jnk / sapk signal pathways

本文將tspdr方法論應用於電力系統多擺失穩現象的研究,電力系統多擺失穩的根本原因在於主導映象系統的非哈密頓特性,經典模型下起主要作用的是互補簇簇內的不同調性,它綜合反映在不平衡功率位置量曲線的非周期程度上。The basic idea for hierarchy - based method is that creating and maintaining a tree of clusters and sub - clusters according to some kind of criterion to measure the distance of clusters, the procedure will be sloped until some terminal conditions are satisfied. hierarchical clustering method can be further classified into agglomerative and divisive hierarchical clustering, depending on whether the hierarchical decomposition is formed in a bottom - up or top - down fashion. most hierarchical clustering methods can produce the better results when the clusters are compact or spherical in shape. but they do not perform well if the clusters are any shape or there are outliers. a main reason is that the most hierarchical clustering methods employ medoid - based measurement as distance between clusters
基於層次方法的聚類的基本思想足:根據給定的簇間距離度量準則,構造利維護一棵由簇利子簇形成的聚類樹,直至滿足某個終結條件為止。根據層次分解是自底向上還是自頂向下形成,層次聚類方法可以分為凝聚的( agglomerative )和分裂的( divisive ) 。人多數層次聚類演算法在緊密簇或球形簇結構下能夠產生較好的聚類效果。The extremely high density of deposited energy of gev heavy ion can be reached with mev cluster beams. under this conditions new phenomena should be discovered
