evolutionary phenomena 中文意思是什麼
-
With the computing program, flow around the square cylinder is resolved at first, and the period of laminar flow is simulated successfully. during the period of vortex street ( re = 100 ), the periodically evolutionary phenomena of the flow behind the square cylinder can be seen
利用計算程序，本文首先對方柱繞流流動進行求解，成功模擬了方柱繞流層流階段的流動和渦街階段（ re = 100 ）方柱尾流的周期性變化現象。 -
The analysis of these two sequences and reported sequences ( three families, 15 sequences in total ) by nj method and the simplest principle shows, the evolutionary trees established by these two methods are consistent and the sequences of the same family constitute one group. the sequences of thaliana and the sequences of brassicaceae each makes up a sub - group in it. the sequences of violaceus distribute in brassicaceae sub - group and this phenomena shows that the relationship is very near
我們對這些序列與已發表的相應序列（合計3個科， 15個序列）用nj法和最簡約性分析，結果表明：由兩種方法構建的進化樹是一致的，同一科的序列形成一組:在十字花科組的分之圖中，來自於擬南芥屬的序列與來自於蕓墓屬的序列又各自形成亞組;來自於諸葛菜屬的序列分佈在蕓墓屬的分之圖中，揭示出諸葛菜屬與蕓矍屬有著極其近的親源關系。 -
The goal of introducing the concept of immunity into the canonical evolutionary algorithms is to utilize some characteristics and knowledge in the pending problems for restraining the degenerative phenomena during evolution, so as to improve the algorithmic efficiency
免疫運算元的作用是在解決工程實踐中一些難度較大的問題時，將有關先驗知識和背景理論與已有的一些智能演算法有機地結合起來，以提高演算法的整體性能。
