  8. Underlying the assumption that the stock price accords with the model of the stock price fluctuating sources, by comprehensivily applying the stochasitic differential theory and no - arbitriagc thcory, this paper, under the conditions that the risk - free rate r is constant or ito stochasitic process, successively works out the option pricing about the stock price model with that the short - term profit function is piecewise lecture function arid that one with that the short - term profit function is possion jump process, derivats counterpart partial differential equation of option pricing. the outcome states : 1. when the short - term profit function is unusual flunctuating sources bring out a piecewise lecture function, this amendment on the lognormal distribution model does not improve the option price, because this partial differential equation of option pricing is the same one underlying the lognormal distribution model ( see equation 2. 14 )

    本文基於股價符合波動源模型的假設，綜合運用隨機微分理論等數學原理和無套利理論等金融理論，依此對短期收益率函數為分段階梯函數和possion跳躍過程的股價波動源模型分別在無風險利率是常數和隨機過程的條件下作了期權定價，推導出了相應的期權定價偏微分方程，結果表明： 1 、由異常波動源帶來的短期收益率函數是分段階梯函數時，這種對股價對數正態分佈模型的修正不能改善期權價格，因為基於這種模型的期權定價偏微分方程與基於股價對數正態分佈模型的期權定價偏微分方程完全相同（見方程2 . 14 ） 。
  9. It seems that the strong interest in the differential equations with piecewise constant argument is motivated by the fact that they describe hybrid dynamical systems which is a combination of the properties of both differential and difference equations. there have been many pa - pers ( such as [ 7 ] ~ [ 15 ] ) concerning these equations

    由於具逐段常變量的微分方程是連續和離散動力系統的混合形式，它既具有微分方程的性質也具有差分方程的性質，從而引起廣泛的興趣，研究此類方程的文獻並不少見，如[ 7 ] [ 15 ] 。

    張傳義在文[ 20 ]中推廣了概周期函數的概念，引進了偽概周期函數的概念，之後有些文獻研究了具逐段常變量微分方程的偽概周期的存在性[ 21 ] [ 25 ] 。
