查询词典 evolutionary tree

In this implementation, the evolutionary algorithm is hybridized with the simulated annealing algorithm and the hill climbing heuristic. The main aspects are as follows. The Metropolis criterion of the simulated annealing algorithm is introduced to select the offspring in order to make the algorithm more effective to escape the local optimum. In terms of the hill climbing heuristic, the local normal perturbing mutation operator based probability selecting is developed to enhance the local searching of the algorithm.

其主要工作是将进化算法与模拟退火算法及爬山方法相组合，引入模拟退火算法中Metropolis接受准则选择子代，提高算法跳出局部最优解的能力：借鉴爬山方法思想，构造了基于概率选择的局部正态摄动变异算子，以强化进化算法局部细搜索能力；同时进化算法以多种群方式实现，在降低计算时间的同时提高算法收敛到全局最优解的概率。

The term evolutionary creationism is used in particular for beliefs in which God transcends normal time and space, with nature having no existence independent of His will.

术语进化创造说被用于特定的信仰，在此信仰里上帝超越了正常的时空，不依赖他的意志自然存在。

The main conclusions from the works presented in this thesis can be as this: for the Galactic OH 1612MHz masers, the radiative pumping mechanism coexists with other mechanisms while some other unresolved problems need to be solved after the launch of more advanced space infrared spectrometer and the more reliable identification of the evolutionary status of the maser bearing infrared sources;the asymmetrical 53.3μm absorption line profile could become a powerful tool to assist us to observationally discriminate the radiative pumping mechanism from other pumping mechanisms in the OH masers.This is the English version of my PhD thesis.

通过本论文的研究工作，我们可以得到这样的结论：在银河系内的OH 1612MHz脉泽中，辐射抽运机制与其它抽运机制并存，而还有一些未解决的问题需要等待更先进的空间红外光谱观测设备的使用并与天体类型证认工作相配合加以解决；不对称的53.3微米吸收线轮廓特征有可能成为帮助我们从观测上对OH脉泽的辐射抽运机制加以鉴别的有力工具。

By helping mammals remember where and when they have eaten a fatty meal, OEA's memory-enhancing activity seems to have been an important evolutionary tool for early humans and other mammals.

那些吃了脂肪膳食的哺乳动物可以帮助促进其记忆，OEA这种记忆促进功能似乎是早期人类和其他哺乳类的一种重要的进化工具。
