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。

The players in different positions have different action combinations in the match. The action combination group is made of different action combination. The players, body action in the match is mostly reflected by action combinations.3. The setter has the most average HR among the match in our excellent men volleyball players. The HR is 143 times every minutes; the assistant spikier,s HR is 136.5 times every minutes; the spikier,s HR is 127 times every minutes; the assistant setters HR is 121.5 times every minutes; and the libero,s HR is 136.5 times every minutes.4. There are some questions in the exercise on specialized physical constitution of our men and women volleyball players. The questions are: the principle about the wholly exercise is not clearly bodied; the exercises are not perfectly coincided the position distinguishing; the exercises of specialized physical constitution are not prominent; the content about the exercises of specialized physical constitution is not like the match.5.

The results show that a the variation of annual mean runoff of Huayuankou section exist an intrinsic dynamic mechanism, which is the results of joint action of affecting factor of periodicity and non-periodicity, having obvious chaos characteristic; b the correlation dimension of attractor of phase space is 5.09 and saturation inserted dimension is 14. It shows that to establish a mathematical model of the annual mean runoff system of Huayuankou at least requires 6 independent variables and the required saturation inserted dimension for rebuilding phase space is 14; c the steady estimate of Kolmogorov entropy is 0.14, showing the average predictable time of the annual mean runoff variation of Huayuankou is about 7 years and; d using nonlinear deterministic chaos model is more suitable to describe the variation of annual mean runoff of Huayuankou.

结果表明：①花园口年平均径流量变化存在着内在动力学机制，是由周期性和非周期性影响因子共同作用的结果，具有明显的混沌特性；②相空间吸引子的关联维为5.09，饱和嵌入维数为14，这说明要建立花园口年平均径流系统的数学模型，至少需要6个独立变量，重构相空间所需要的饱和嵌入维数为14；③Kolmogorov熵的稳定估计为0.14，说明花园口年平均径流量变化的平均可预报时间大约为7年；④用非线性确定性的混沌模型比完全的随机模型更适于描述黄河花园口年平均径流量的变化。

Of 12 tomato lines, the analysis on the 4 fruit nourishment quality traits (the contents of vitamin C, total soluble solids and dry matter and ratio of sugar-acid ) was carried out to study the four kinds of disparities, which included the interspecific one, the one between two varieties in the same species , the one between the lines bred by different means in the same variety ,and the one between the different fruit-shaped lines in the same variety .The analytic method of orthogonal comparison of single degree of freedom was applied. The results showed that the line of Lycopersicum pimpinellifolium was better than the average of the lines of L.esculentum in the 4 traits at significant level of 1%, the average of the lines of var.cerasiforme was better than the average of the lines of var.vulgare in the 4 traits at significant level of 5% or 1%,and the two space mutation line(YH02-2 or YH02-6) was better than the average of the other lines of the same variation in the 4 trait, respectively, at significant level of 1%. Of the lines of var.cerasiforme , the lines with pear fruit were lower than the average of the lines with round-shaped or plum-shaped fruits in the 2traits(the contents of vitamin C and total soluble solids), at significant level of 1%,the lines with plum-shaped fruits were higher than the average of the lines with round-shaped fruits, at significant level of 1%,and the lines with yellow-colored fruits(YH02-11) was lower than the average of the lines with red-colored fruits(YH02-1and YH02-7) in the trait of the contents of vitamin C.
