  1. Therefore , we need more concrete function to better discribe the variation of some biological populations in our real world . the two important indexes r ( t ) and k ( t ) of logistic equation are asmptotic periodic function , and discussed by author . the asmptotic solution of the asmptotic periodic logistic function is obtained
    因而，為了更好地刻劃客觀世界，我們需要用更加符合客觀實(shí)際的函數(shù)來(lái)描述生物種群的變化，于是作者對(duì)logistic方程的兩個(gè)重要的參數(shù)r ( t ) ， k ( t )分別是漸近周期函數(shù)時(shí)，研究漸近周期logistic方程的漸近周期解，并且得到了解的存在性，唯一性，全局吸引性等一些良好的性質(zhì)
  2. This paper begins with the restrictions of the - existent net - flow modelling methods . integrated with the characteristics of modern net - flow system and utilizing francesco luna ' s idea of pcrceptron and xor function , we express human ' s consciousness with logistic function of perceptron , and the uncertain relations among nodes are mapped to xor function . on the basis of these , a new modelling method of net - flow is offered
    本文從已有網(wǎng)流系統(tǒng)建模方法的局限性出發(fā)，結(jié)合現(xiàn)代網(wǎng)流系統(tǒng)的特征，利用francescoluna的感知器與異或問(wèn)題的思想，將人的意識(shí)用感知器對(duì)應(yīng)的邏輯函數(shù)進(jìn)行描述，節(jié)點(diǎn)之間連接關(guān)系的不可感知性映象為異或函數(shù)，提出網(wǎng)流系統(tǒng)的一種新的建模方法。
  3. The connecting states of nodes are uncertain and the linking relation between two adjacent nodes is unperceptible in advance , so this unperceptivity can be mapped to xor function ; when forming the access of flow , not all nodes can become the node on the access . to a certain degree , the form of access embodies intelligence of human , this ability of choice can be mapped to logistic function
    網(wǎng)流空間中各個(gè)節(jié)點(diǎn)的連接狀態(tài)是不確定的，節(jié)點(diǎn)與節(jié)點(diǎn)間的連接關(guān)系預(yù)先不可感知，這種不可知性可以映象為異或函數(shù)；節(jié)點(diǎn)在形成流的通路時(shí)，并不是所有節(jié)點(diǎn)都可以成為通路上的點(diǎn)，流質(zhì)通路的形成在一定程度上體現(xiàn)了人的“智能性” ，這種選擇能力用邏輯函數(shù)來(lái)映象。

百科釋義

    A logistic function or logistic curve is a common sigmoid function, given its name in 1844 or 1845 by Pierre Fran?ois Verhulst who studied it in relation to population growth. A generalized logistic curve can model the "S-shaped" behaviour (abbreviated S-curve) of growth of some population?P.
