This old tree, not suitable for students in the Royal gardens, officials are not suitable for long in other people's yard, it is left to the tree's effemination it like growing up in a remote mountainous area of Henan province in a corner and there is It's paradise - a ruminant of cattle, two quiet farmhouse in the village, in Montreal, the new green shoots of.

这样的老槐树，不适合生在皇家园林，也不适合长在官宦人家的庭院里，那是留给娇气的树们的，它喜欢生长在豫南山区某个偏僻的角落里，那里是它的天堂——一头反刍的黄牛，两座寂静的农舍，在村口，在满地嫩芽的新绿之中。

The phylogenetic tree of fish IgH conserved region contains two major branches of teleost and elasmobranch, and snakehead IgH is most closely related to pufferfish. The phylogenetic tree of IgL conserved region shows three major branches, and snakehead IgL locate as a branch of IgL1A.

根据IgH和IgL恒定区氨基酸序列构建系统进化树，鱼类IgH形成硬骨鱼和软骨鱼两大分支，其中乌鳢IgH与河豚IgH的亲缘关系较近；硬骨鱼IgL系统树显示3个主要的分支：L1、L2和L3，乌鳢IgL位于L1分支的L1 A亚类。

To solve QoS-constrained routing problem and the problem of balancing network load, an algorithm based on tabu search is proposed, which has a better ability of balancing the cost of the multicast tree and the network load; upon this algorithm, a new algorithm based on degree-constrained and load-balance is proposed, which has a nicer integrative performance on equipoise the cost of multicast tree and the load of links and nodes.

2针对网络负载均衡的QoS问题，提出基于禁忌搜索的负载均衡QoS组播路由算法，算法能平衡组播树代价和网络链路负载均衡状况；在此基础上提出了基于度约束和负载均衡的QoS组播路由算法，算法在满足QoS约束的基础上，均衡了组播树代价、网络链路负载和节点负载三者之间的关系，综合性能良好。

In addition, several RC tree modals about delay of transmission line are compared and analyzed. A new method using Euler formula is brought forward to solve the RC tree, which leads to higher efficiency with the same accuracy.

同时，还对关于传输线延迟的几种RC树模型进行了比较分析，并提出了一种新的Euler方法，仿真表明，这种方法速度更快，效率更高。
