  3. 4. after changing the short - term profit function to possion jump process, in the view of that the derivated partial differential equation of the option pricing which different from black - scholes partial differential equation still is that interest rate is constant ( 4. 2 ), the model which does not accord with the real market under the assumption. at last, we derivat a new model of option pricing whoso profit rate is possion jump process under stochastic interest rate ( 5. 13 ), this model not only changes the form of the short - term profit function of the stock price model and avaids the simplization of the profit rate function the unusual flunction sources bring about, but also relaxes the basis assumption of black - scholes option pricing model and makes that the partial differential equation builds the foundation which even approaches the actual market

    4 、將短期收益率函數由確定函數修改為possion跳躍過程后，文[ 15 ]推導出的期權定價偏微分方程（見方程4 . 2 ）雖然推廣了black - scholes期權定價偏微分方程，但此時依舊假設利率是常數，這與實際生活中的不符，我們研究了一個隨機利率下短期收益率函數是possion跳躍過程的期權定價模型（見5 . 13 ） ，該模型既改變了股票價格波動源模型中短期收益率函數的形式，避免了異常波動源帶來的收益率函數的簡單化。
