A sort of autonomous agent construction method based on adaptive symbiotic evolutionary model was proposed,and by using adaptive symbiotic evolution algorithmas an evolutionary reinforcement learning method,Which can design neural network decision making systems effectively. while at the same time this method can accelerate the learning and convergence speed in the behavior evolution problem of multi agent autonomous system,and it also prevents premature convergence and promotes population diversity.

文章研究了一类基于自适应共生进化模型的自主体构造方法，提出了基于自适应共生进化算法的一种进化强化学习方法，该方法不仅可以高效地进行神经网络决策系统的设计，而且在多自主体组成的自律系统的群体行为进化中可快速学习而收敛，并且通过多样度调节维持了群体多样性，克服了未成熟收敛现象。

Apparently, the evolution have generated the situation of the separation of monosyllabic form and disyllabic form, and thus generated the form system of direction words. The totally different paralleling dual system is the basis of the later evolution. The monosyllabic and disyllabic direction words has gradually come into the weakened meaning or morpheme,while disyllabic direction words has more substantive nature,with more freedom in the sentences.

可见，语义的发展变化最终导致了汉语方位词形式系统单双音节两分的局面，这两种形式方位词的不同语义特点也是后来发展演变的基础，单音节方位词逐渐走向虚词性或词法平面，而双音节方位词则具有更多的实词性，更为自由地出现在句子中。

Taking the symbolic evolution of the fish pattern as the foundation, this article expounds the evolutional course of the model of the fish emblazonment from the originally natural form to the abstract form and the evolution from the originally emblematic meaning to decorative meaning, which mark the gradual progress of the way of thought in the traditional design from the elementary stage to the advanced stage.

本文以鱼形纹饰的象征性流变为理论基础，论述了鱼纹的造型从最初的象征意义到现代的装饰意义的流变，在此流变过程中体现了传统设计思维方式从低级阶段向高级阶段发展的渐进过程。

The result suggested that different genomes had different genetic speed or stability during evolution.3 The similarities co-efficiency between wild emmer and hexaploid synthetic was higher than that between wild emmer and common wheat. So that crossing among species is not a simple combination of genomes, but involve introgression of chromosomes, and the evolution made by this action was bigger than that made by environment.4 According to the results of salt tolerance identification, the salt tolerance of wild emmer is lower than that of common wheat in the whole.
