  1. This thesis has studied the dynamic features of a class of the discrete - time neural network model of two neurons, such as the convergence and periodicity and etc. the function of the neuron signal transmission in this model, which belongs to three piecewise constant argument, indicates the following charactersif the signal of one neuron on the network is active between a and b, it will produce invariable encouragement effect on another neuron ; if the signal of one neuron is lower than a, it will produce invariable restrain effect on another one, if the signal of one neuron is higher than b, it will produce no effect on another one

    本文研究了一類二元離散人工神經網路模型的解的收斂性及周期解的存在性等動力學特徵。該模型的神經元信號傳遞函數是三段常數不連續函數。這種信號傳遞函數表明如果某神經元的信號在a與b之間活躍，則它對另一個神經元產生恆定的激勵效果，如果某神經元的信號低於a ，則它對另一個神經元產生恆定的抑制效果，如果某神經元的信號高於b ，則它對另一個神經元不產生作用。

  3. After analyzing and testifying, researching and discussing character and connotation of economic entropy indicates that it conforms with the basic rules of the systematic science, reflects subjective basis ? prime contents ? periodicity and fluctuation of regional economic growth ; above all, providing subjective basis is a basic connotation of economic entropy, for function provides more solid micro - basis and new theoretical method for researching and exploring regional economics though it is a applied economics

    在數學分析和理論驗證后，論文對經濟熵的性質和內涵進行了理論研究，指出，應用經濟熵對區域經濟的研究符合系統科學的基本原則，經濟熵反映了區域經濟發展的主觀基礎、基本內涵、波動性和周期性。其中，提供區域經濟發展的主觀基礎是經濟熵的基本意義之一，這為研究區域經濟這門應用經濟學提供了更堅實的微觀基礎和新的理論方法;接下來，應用經濟熵分析了區域存在的主觀性和客觀性、區域的本質、區域差異的演化過程。
  4. The analysis shows that by using correction function processing to the collected signals, the periodicity of the signal can be checked conveniently, the frequency - domain response of linear systems with uncertain parameters can be identified, useful signals can be checked out and extracted from the noise

    由分析可知，對採集到的信號做相關函數的處理可以方便地對信號的周期性進行檢測，確定未知參數的線性系統的頻域響應，檢測噪聲中有用信號，並對噪聲中的信號進行提取。
  5. The correlation detection using the periodicity of the direct sequence autocorrelation function can estimate the symbol period at intermediate frequency or at baseband. simulation results indicate that the former is superior to the latter when the demodulated frequency is unequal to the carrier frequency

    時域相關檢測方法利用擴頻信號的周期自相關特性，能在中頻和基帶對擴頻碼周期進行估計，模擬結果表明中頻檢測時性能較好。
  6. The whole paper consists of three parts : part is about general theory of the least positive period, which argues the necessary and sufficient condition for the existence of the least positive period for a periodic function, and concludes " the existence of the least positive period for that periodic function, which is continuous at least one point and not equal ever to a constant " ; part researches the least positive period for the sum of two periodic functions, followed its general expression ; part discusses non - periodicity for the compound function constructed by a periodic function and a non - periodic function, and the corresponding results

    全文分為三部份：第一部份是關于最小正周期的一般理論，得到了周期函數有最小正周期的充分必要條件，也獲得了「至少在一個點連續且不恆等於常數的周期函數必有最小正周期」的結論；第二部份分析了兩個周期函數之和的最小正周期的問題，給出了其一般表達式；第三部份討論了周期函數與某些類型的非周期函數構成的復合函數的非周期性問題，並得出相應結論。
  7. [ 3 ] the vowel ' s self - correlation function has periodicity and the period of this function is the fundamental sound period of this speech. according to this, we propose a method of adjusting the tone in temporal field by adding or deleting the sampling points in the waveform with the whole speech waveform unchanged

    （ 3 ）根據母音自關函數具有周期性並且其周期就是語音基音周期這一特性，提出在保持語音波形總體不變的前提下，在語音時域上對語音進行插值或刪值的方法來調整音調。
