( ii ) this paper makes the annals data of the listed companies in 2004 as sample, and gets earnings per share and the regression equation of the four financial indexes which have noticeable effect on it via stepwise regression method. the four financial indexes which affect earnings per share are the net asset per share, unaccommodated profit per share, quick ratio and return on assets respectively. the equation provides a
（二） 、以河南省上市公司2004年年報數據作為樣本，應用逐步回歸方法，得到每股收益和對它有顯著影響的四個財務指標的回歸方程，影響每股收益的四個財務指標分別是:每股凈資產、每股未分配利潤、速動比率和總資產報酬率，為這些上市公司提高每股收益提供參考。 -
Using this estimating equation, the manager can predict what the annual profit will be from the amount budgeted for research.
用這個估計公式，經理就可以根據科研預算經費額測算出年利潤額。 -
The equation shows that 9 finance index have important relationship with default ratio, they are roe, debt ratio, asset turnover ratio, gross profit ratio, scale of assets, currency ratio ( [ currency + marketable securities ] / current liability ), debt structure ( current liability / total debts ), currency / daily revenues and quality of assets ( accounts receivable / total assets )
回歸方程表明，違約率與以下9個財務指標的組合密切相關：凈資產收益率、資產負債率、總資產周轉率、毛利率、資產規模（資產總額對數） 、現金比率（現金類資產流動負債） 、債務結構（短債總額債務總額） 、日銷現比（現金與有價證券日銷售額） 、資產質量（應收賬款資產總額） 。 -

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 ） 。 -
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。 -
An optimal model of pre - stress steel truss is presented based on reliability. the reliability index is replaced by subentry coefficient in optimal model restrict equation, and deal with corresponding restrict conditions with applied expressions. linear programming associated with full - constrained methods are used in this paper, which improve the profit of multi - pre - stress steel structure design and the reliability of structures as well as model and arithmetic
本文分析考慮可靠性的預應力鋼結構的優化理論，建立了基於可靠性的預應力鋼結構的優化模型，將可靠度指標以分項系數的形式引入優化模型的約束方程當中，以實用表達式形式處理相應的約束條件，並採用線性規劃和滿約束準則結合的方法進行優化，既提高了多次預應力鋼結構設計的效益，又保證了結構的可靠性，模型和演算法更加完善。
