混沌初開 的英文怎麼說
中文拼音 [húndùnchūkāi]
混沌初開
英文
the dawn of civilization-
The control of beam halo - chaos becomes a critical problem in the development of high intensity accelerator. efforts to remove the halo by collimation have been largely unsuccessful since the halos almost always regenerate. the mechanisms of halos are complex, such as nonlinear resonances and chaotic behavior etc. considering this, professor fang jin - qing who works in china institute of atomic energy pointed out that the theory of chaos control can be used to control beam halos. he presented the method to control halos by using nonlinear functions, which means nonlinear function g is added to the right of ion radial self - edlctric force equation and some nonlinear function are selected to control beam halos in simulations. in paper [ 69 ], controllerg = - 0. 15sin ( rmax - am ) 2 was used and the halo intensity was decreased to 0. 1078, the halos are removed partly
束暈?混沌的控制是新一代強流加速器研製的關鍵問題,隨著強流離子束應用前景的日趨廣闊而日益成為研究的熱點。傳統機械限束器因無法解決束暈的再生而收效甚微,因為束暈的形成有著其內在動力學機制?非線性共振以及混沌等。基於此,中國原子能科學院研究員方錦清將混沌控制的理論和方法開創性的運用於束暈?混沌的控制上,提出了控制束暈?混沌的非線性控制策略,即在粒子徑向所受束自生場力方程的右邊加上非線性控制函數g :並選取一些非線性函數如等進行了控制的模擬研究,將束暈強度控制在0 . 1078左右,取得了初步的控制效果。The sky and the earth were at first one blurred entity like an egg
最初,天地混沌未開,像一個大雞蛋,盤古就生在其中。By combining chaotic dynamics and converging dynamics together, the neural network transit gradually to hopfield neural network is made. by introducing converging factor, the aim of controlling chaos is attained, which provides initial value of hopfield neural network that is near to the global optimal solutions, and solve the problem of local minimum. the principle of genetic algorithm is analyzed, and the design and of genetic algorithm are studied
通過把混沌動力學與收斂動力學相結合,使網路逐漸由混沌神經網路向hopfield網路過渡,達到控制混沌的目的,並且提供了一個在全局最優解附近的初值,避開了神經網路權值初始化沒有理論依據的難題,無須確定連接權值和閾值,使神經網路具有物理意義明確、便於與工程應用相結合的特點。
