摘要推導出在近親交配下一對等位基因群體母子間的基因型聯合概率分佈列；定義了在近親交配下母子間的基因型聯合信息熵；討論了在世代交替中母子間的基因型聯合信息熵的性質及其信息學解釋；並用計算機模擬驗證。Combined with the practical program, the problems of united dispatching of reservoir system in yeerqiang river basin is studied deeply in this paper by using the theory and method of system science, the model of operation of reservoir system is purposed, the characteristic water level of aertashi reservoir are selected, the operation function of aertashi reservoir is established to direct the operation in the future
論文結合生產實際，採用系統科學的理論與方法對葉爾羌河流域水庫群調度問題進行了研究，提出了葉爾羌河流域水庫群調度的模型，優選了阿爾塔什水庫的特徵水位，並根據長系列結果建立了阿爾塔什水庫調度函數以指導水庫將來的運行。The interaction of wave with multiple porous circular cylinders is analyzed also. the approximate value of the hydrodynamic force act on each porous cylinder can be calculated
在此基礎上進而分析了波浪對可滲透圓柱群的相互作用，推導出了作用於直線排列的群柱中單一柱體上的波浪力的近似解。A perturbation method by tight - binding approximation which provide the relation of phase constant and angular spectrum of fields of in - waveguide is presented. the strip width of phase constant can be given. on the other hand, the group delay - time due to the k dispersion in single - mode transmission can also be estimated
提出一種利用緊束縛近似的微擾法計算陣列波導的相位常數與輸入光角譜的關系，由此算出相位常數的帶寬，並利用衍射方法估算單模傳輸中k色散引起的群延時。In this essay, firstly the author analyzes the predictability of time series from china ' s stock exchange using three kinds of methods : arma model, neural network model and non - parametric estimation and gives evaluation on their performances while at the same time puts forward some conclusions deserving attention from both stock exchange supervising department and stock traders. secondly, the author examines the assumptions closely on which the above - said methods base and gives a detailed discussion on them, especially using garch model to test quantitatively the stability of china ' s stock exchange, afterwards drawing the conclusion that it is hard to make accurate prediction of price or return rate of china ' s stocks for none of the assumptions fully holds ground. thirdly, taking account of the difference between chinese stock traders as a whole and that of developed countries, the author gives a thorough analysis on the complexity and volatility of its ( traders " ) reaction to information and points out that the intrinsic heterogeneous and volatile reaction to information is an important reason for the almost unpredictability of the price or return rate in china ' s stock exchange
本文首先採用arma模型、非參數模型以及神經網路模型對我國股市時間序列進行研究，對三種方法在分析我國股市時間序列的表現進行評價，並得出了一些對監管部門以及股票交易者有借鑒意義的結論；其次作者對三種模型分析我國股市時間序列的前提進行了討論，特別是利用garch模型對我國股市的系統穩定性進行了量化檢驗，得出了前提難以滿足導致準確預測我國股市價格或收益率困難的結論；第三，考慮到中國股市股票交易者群體與發達國家股市股票交易者群體之間的差異，作者借用行為金融學的理論成果對我國股票交易者對信息反應的復雜性和易變性進行了詳細分析，指出股票交易者對信息反應的異質性和易變性是造成難以準確預測我國股市的一個重要原因，考慮到我國股市以散戶為主導的特性將長期存在，因此將行為金融學的研究結論納入對我國股市時間序列的量化研究具有重要的意義；最後，作者從唯理預測與唯象預測之間差異的角度出發，指出了唯象預測的缺點並對我國股市時間序列的研究方向進行了展望。The pile group and the surrounding soil are discretized into horizontal layers, which meets a plane strain assumption. by means of that the single pile dynamic impedance is developed with a transfer matrix method, the pile - to - pile dynamic interaction factor is derived. then, the dynamic impedances of rigidly - capped pile groups with due consideration to pile - soil - pile interaction for vertical oscillations are produced
本論文充分考慮土的成層性和沿深度有變化的特性，將土層沿深度離散形成一系列均質的土層，各土層視為滿足平面應變假定，應用傳遞矩陣法推導出單樁在成層地基中的動力阻抗；並據此研究了在成層地基中的樁-樁動力相互作用因子，然後推導了群樁剛性承臺豎向動力阻抗。分享友人
