查询词典 evolutionary tree

If you do use this method in learning how to kill a tree stump, set fire to some dry wood on the tree stump and let it keep burning down, and while the tree stump slowly catches alight, keep feeding the fire with dryer wood to keep the tree stump burning until it has burnt completely away.

如果您使用此方法在学习如何杀死树桩，放火焚烧一些干材的树桩让它保持烧毁，虽然树桩缓慢渔获下车，继续喂养消防干燥木材与保持燃烧的树桩，直到它已完全被烧毁了。

N AVL tree which is often used to store data is a height-balanced binary search tree.A historically popular alternative to the AVL tree is the red-black tree.

VL树是一种平衡二叉查找树，经常用来组织数据，红黑树是AVL树的有效替代者。

First a hierarchically structured genotype is applied to represent cycloid parameters, and selection and mutation operators with evolutionary art are used to generate diverse patterns. Those with higher user rating are stored into the pattern database. Then fractal theory is introduced to configure these patterns on the basis of two distinct methods-Pythagoras tree design and Curlicue Fractal design.

采用层次结构化基因型表示摆线参数，使用进化艺术思想进行选择、变异操作，生成造型各异的花形图案，将用户评分较高的图案存入图案数据库；引入分形理论将图案库中的元件进行组装，提出基于Pythagoras树和花体分形原理的2套组装方案。

Neighbor-Joining analyses of teleost hepcidins showed that the eelpout 4cys variant arose independently from the notothenioid version, which lends support to adaptive evolution of reduced cysteine hepcidin variants on cold selection. The NJ tree also showed taxonomic-specific expansions of hepcidin variants, indicating that duplication and diversification of hepcidin genes play important roles in evolutionary response to diverse ecological conditions.

另外我们在另一种生活于南极水域的eelpout中也发现了一种含有4个半胱氨酸残基的hepcidin，而eelpout和南极鱼notothenioid在分类学上分属于不同亚目，是一类相差较远的物种，利用Neighbor-Joining方法建树分析发现eelpout的hepcidin虽然同样仅含有4个半胱氨酸残基，但和notothenioid的4cys_hepcidin有着不同的起源，这也进一步说明了hepcidin中半胱氨酸残基数目的减少确实是对寒冷环境的一种适应性进化。

In an experiment of constructing a phylogeny of the Eutherian orders, its results not only support the Rodents,(Ferungulates, Primates grouping, but also give an evolutionary tree that is identical to the one constructed by the maximum likelihood method, which indicates that sequence distance defined is very effective to measure the relatedness between sequences.

在研究基于基因组序列的进化关系的实验中，不仅支持了哺乳类动物中（啮齿动物，（灵长类动物，Ferungulates））进化关系分类的结论，而且构造的进化树也与由最大似然方法构造的进化树完全一致。这充分说明了我们给出的序列距离对度量序列相似性是非常有效的。

The latest in a series of recent hominid discoveries provides another enigmatic branch in the human evolutionary tree.

一系列远古人类的最新发现在人类进化树上产生另一个难以理解的分支。

Currently, a rich variety of evolutionary tree reconstruction methods have been developed, which fall into three categories, distance based methods, maximum parsimony methods and approaches applying the maximum likelihood principle.

一个可靠的进化树推断不仅有助于了解生物的进化历史和进化机制，而且对生物医药学、计算分子生物学其他分支的研究具有重要意义。

However, for hill-climbing strategies to be guaranteed to find the global optimum the optimality landscape must be unimodal. Moreover, research has demonstrated that multiple maxima exist under the maximum likelihood principle. Therefore, hill climbing based evolutionary tree reconstruction methods often return local optima.

但是由于进化树的似然函数通常含有多个局部极优解，而爬山算法没有逃离局部极优的能力，因此基于爬山算法的进化树构建算法很容易陷入局部极优。

Inferring an accurate evolutionary tree of life requires high-quality alignments of molecular sequence data sets from large numbers of species.

推断生命的一个准确的系统发育树需要来自大量物种的分子序列数据集的高质量的比对。

According to the problem of game tree solution, the immune evolutionary algorithm was designed, the Bayesian Nash equilibrium was carried out, and the best strategy sequence was achieved.

以不完全信息动态博弈理论为基础，无人机攻防对抗问题为背景，建立无人机攻防对抗问题的不完全信息动态博弈模型；针对博弈树的求解问题，设计免疫进化算法，求解问题的贝叶斯纳什均衡解，得到无人机的最优策略序列。
