4Based on a fact that the price formula of Asian options can be transformed into that of vanilla European option when the time to maturity is less than or equal to the length of average, we skillfully obtain the analytical price formula for the option on the minimum or the maximum of two geometric average prices and generalize it to obtain the price formula of several average prices for the first time. We also apply the method of [121], which approximates the arithmetic average by the geometric average, to the pricing of opitons on the minimum or the maximum of two arithmetic average prices to obtain Its approximated price formula. Numerical results show that the approximated price is relatively accurate when the riskless interest rate is large or the option is in the money and the volatility of two underlying assets are high and its accuracy is a little reduced but still good when the dividends are considered. However, it is hardly affected by the sampling number.
我们基于观察到的一个事实即当离到期时间小于或等于平均期间时亚洲期权的价格可变换成普通的欧式期权的价格,从而巧妙地得到了两个几何平均价格的最小或最大值期权价格的解析公式,通过简单地推广,首次得到了多个几何平均时的价格公式;将[121]用于算术平均亚洲期权的定价方法推广到两个算术平均价格的最小或最大值期权,从而得到它的渐进公式,数值结果表明:渐进价格的准确性在无风险利率较大或期权为实值且两标的资产的波动率较小时较好,抽样的个数对它没有影响,但考虑红利时它稍有下降但仍较好。

It showed that the halophile of Kenyu7 were better than Wuming-5;(2)the contents of proline of the two Zea mays varieties increased significantly,and under high NaCl stress(150mmol/L NaCl or above) the increasing amount of the contents of proline of Kenyu7 was higher than Wuming-5 ,so it showed that the injuries of Wuming-5 imposed by NaCl stress was greater than Kenyu7;(3)the activities of CAT of the two varieties were no obviously changed,while the activities of CAT of Wuming-5 were all higher than Kenyu7 under all concentrations of NaCl solution,which hadn't showed the correlation between the activity of CAT and salinity tolerance.
结果表明,随NaCl溶液浓度的增加:(1)两品种玉米生长均受到严重抑制,发芽势降低,芽和根的长度均呈减小的趋势,总体来看,杂交种垦玉7的发芽势、芽和根的长势均好于自交系无名-5;(2)两品种玉米体内Pro含量均增加,且在NaCl浓度超过150mmol/L时,杂交种垦玉7体内Pro含量增加的幅度明显大于自交系无名-5,而使垦玉7对盐的适应能力强于无名-5;(3)两品种的CAT活性变化幅度均不大,但无名-5的CAT活性在各NaCl浓度条件下均高于垦玉7,这可能是由品种间本身差异造成的,而与品种的耐盐性无直接关系。
