The relaxation iterative method of branch flow in tree - type river systems is extended to the loop - type river networks, which can turn the problem of any complex river networks hydraulics into the problem of a series of single river hydraulics ; 4
將樹狀河系支流流量的鬆弛迭代方法推廣為環狀河網支流流量的鬆弛迭代方法,從而實現了對于任意形式河網的復雜水力計算問題都化為一系列的單一河道的簡單水力計算問題。 -
The data matrix for the 37 taxon contained 553 variable sites ( 57. 6 % ), of which 336 were phylogenetically informative. the phylogenetic relationships were inferred using the neighbor - joining and maximum - parsimony methods. in mp method, the heuristic search generated two single most parmonious tree
雙蓋藏屬diplazium 、菜蔽屬c公刀ipteris 、短腸蔗屬allantodia和腸獲屬diplaziopsis構成單系起源,在兩種系統樹中分別得到98 % ( mp )和100 % ( nj )的支持率。 -
The creativity of the work in the paper can be shown as the following four aspects : ( 1 ) for single subnet, the condition of simple link judgement is added into the ptda, so the algorithm is improved well ; ( 2 ) for multiple subnets, the ptda becomes more effective, benefited from use of breadth - first - search algorithm of graph, port - deletion method etc ; ( 3 ) due to suitable adoption of the three protocols stp, snmp and arp, the ptda based on spanning tree protocol can get very effective and correct ; ( 4 ) owing to the employment of ieee802. 1 q, the ptda of vlan is all - purpose to some extent
本文的創新之處主要體現在以下四個方面:在單子網物理拓撲發現演算法中,增加了判斷簡單連接的條件,使演算法更加完善;在多子網物理拓撲發現演算法中採用圖的廣度優先遍歷方法、埠刪除方法等,該演算法更加有效;在生成樹協議物理拓撲發現演算法中,正確使用stp 、 snmp和arp三種協議,物理拓撲發現非常準確;在vlan物理拓撲發現演算法中,正確運用了ieee802 . 1q協議,該演算法具有通用性。
