  1. It showed that activated inhibition by weak noise could be gabaergic inhibition. from above the findings, we could give a hypothesis that the input of random oscillation induced by noise in the cochlea to central auditory system could be integrated in the central auditory nucleus and the response of sound - sensitive neuron to sound stimuli could be adjusted to an optimum state for signal intensity coding

    根據這些變化可以推測,這種背景噪聲的生物學作用可能是通過弱噪聲所引起的耳蝸共振的輸入,在上行過程中經各級聽覺核團的整合,將中樞聲敏感神經元調定在一種準備狀態,並定型放電率和調神經元對聲馨碩士學位論文master 』 st砰iesis的編碼。
  2. 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?混沌的控是新一代流加速器研製的關鍵問題,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?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的理論和方法開創性的運用於束暈?混沌的控上,提出了控束暈?混沌的非線性控策略,即在粒子徑向所受束自生場力方程的右邊加上非線性控g :並選取一些非線性如等進行了控的模擬研究,將束暈度控在0 . 1078左右,取得了初步的控效果。
  3. Based on the study of strength degradation of material in the fatigue process, a strength degradation model is proposed. a stochastic differential equation, which controls strength degradation, is obtained from the model randomized by markov process. by using the theory of stochastic, the distributions of residual strength at any given lifetime and lifetime of any given residual strength are attained. under a few suitable hypotheses, inverse gaussian distribution of fatigue life is derived, and verified by means of experimental data. the result shows that the model and the method are reasonable

  5. The problem has been studied from two sides, firstly, from the viewpoint of applicability, based on the development strategic objectives of the oil company, with the aim to unify the exploration and extraction decisions of the resources in an integrated framework, and integrate the macro economic and technical objectives with micro economic and technical models of an oil well, an integrated non - linear dynamic optimal control model has been constructed, the objective is the benefit maximum of the exploration and extraction of the resources, and the optimal strategies are obtained by changing the problem into a non - linear mathematical programming problem, on the other hand, from the more macro level, based on the analysis of the characteristics of the exploration and extraction activities of oil and gas resources, a conclusion is easily deduced that the procedure is full of randomicity, then discovering procedure of oil deposit is proved to be a poisson process, and the reserves process is a supermartingale process, so the model of exploration discovery rate and the reserves model could be constructed

    本文從兩個側面對此問題進行了研究,首先從實用性出發,以公司層次的戰略性規劃目標為基礎,將勘探階段與開發階段的工程技術及經濟方面的決策整合在一個模型框架內,同時將宏觀層次的經濟技術目標與單個油氣井生產的微觀技術經濟模型相結合,以油氣資源勘探與開發的經營效益最大化為目標,建立了一個非線性確定型綜合動態優化模型,通過將原非線性最優控問題轉化為一非線性學規劃問題進行了求解。其次從相對更宏觀的層次上,通過對油氣資源勘探與開發的特點分析,認為具有很性,證明了勘探活動發現油氣藏的過程為一泊松過程,所發現的油氣藏儲量為一上鞅過程,在此基礎上,建立了油氣藏勘探發現率模型及儲量模型,在油氣價格服從幾何布朗運動條件下,以油氣開採收益最大化為目標,建立了一個油氣資源勘探與開發的最優控模型,採用動態規劃方法得到了值的hjb方程,並針對方程的特點,以及方程及其變量所對應的經濟學意義,對最優策略的求解進行了一些討論。
