This paper will assume that there are effective stock market and effective executive market, and the basic hypothesises in Black-Scholes Stock Options Pricing Model are correct. We will discuss the optimal repricing scheme under three situations, one is that the board of the company considers repricing when the price declines straightly ; the second is at the beginning of stock life,the board promises to reprice under some conditions at a certain coming time; the third is when some condition happens at an uncertain coming time, the board promises to reprice the ESO.

本文在有有效的股票市场，也有有效的经理人市场，Black-Scholes期权定价模型中的基本假设是正确的条件下，分别讨论了公司的董事会在股价持续下跌时考虑重新定价、在授予经理人期权的时候就承诺在未来某一确定时刻一定条件下可以进行重新定价和未来不确定时刻一定条件下可以进行重新定价三种情况下的最优重新定价问题。

Three approximate methods (called as scaling, rectangle and trapezia methods respectively) for performance analysis of orthogonal space-time block code with M-ary phase shift keying and M-ary quadrature amplitude modulation over flat Rayleigh fading channels are proposed, and their approximate performance expressions are given.

在平坦瑞利衰落信道下，提出了3种正交空时分组码在MPSK和MQAM调制下的近似性能分析方法(分别称为放缩法、矩形法和梯形法)，并给出其近似表达式。

In this way,after the viscosity or apparent viscosity of virgin crude,corresponding unsheared PPD-beneficiated crude and the sheared PPD-beneficiated crude at a certain temperature are determined,the parameters in the model can be calculated.

按照此方法，只须测定一定温度下空白原油的粘度或表观粘度、未剪切时加剂原油的粘度或表观粘度，及在某一个剪切温度下及某一个粘性流动熵产条件下原油的粘度或表观粘度，即可近似确定该数学模型中的参数，从而预测在不同温度时剪切后的原油在该温度下的粘度或表观粘度。

The result shows that the hydrogen storage properties increase remarkably after pure magnesium ball-milled with 10% TiFe(subscript 1-x)Cr (x=0, 0.3). Moreover, the chromium content also influences the hydrogen storage characteristics. Furthermore, the ball-milled composite of Mg+10%TiFe0.7Cr0.3 has the best hydrogen storage properties with hydrogenation capacity of 7.14% and dehydrogenation capacity of 6.91% at 613 K. In addition, the lower temperature of 493-573 K, the Cr-contained composite exhibits the best dehydrogenating kinetics.

研究结果表明：在纯Mg中添加质量分数为10%的TiFe(下标 1-x)Cr(x=0， 0.3)进行复合球磨，可以明显提高其吸放氢性能；在相同温度条件下，x=0.3的含铬复相合金具有最佳的吸放氢性能，其中在613 K下的吸氢容量为7.14%，放氢容量为6.91%；在493~573 K的较低温度下，含铬复相合金表现出更好的放氢动力学性能。
