Usually, it encounters dynamic group membership in practical multicast applications. Adopting the idea of Greedy algorithm, this thesis presents a delay constraint dynamic multicast routing algorithm DDMP, based on k-shortest paths, finds a path for the node which apply for join in the tree.
最后,由于在实际组播应用中,通常面临着组播成员的动态变化的问题,论文借鉴了贪婪算法的思想,提出一个基于K条最短路径算法的时延约束动态组播路由算法DDMP。
Total glycosides were extracted from soybean hypocotyl. The Group B saponin Ba and Bb, Group E saponin Bd and Be and DDMP saponin α g and β g were isolated and purified by C18 column chromatography and high-performance liquid chromatography ( HPLC).
从大豆胚轴提取总糖甙,以C18柱层析法和高效液相色谱法(HPLC)分离纯化B类皂甙Ba和Bb、E类皂甙Bd和Be、DDMP皂甙αg和βg。
