查询词典 two-time

It is shown that two-component Wadati-Konno-Ichikawa equation, i.e. a generalization of the wellknown WKI equation is obtained from the motion of space curves in Euclidean geometry, and it is exactly a system for the graph of the curves when the curve motion is governed by the two-component modified Korteweg-de Vries flow. At the same time, a n-component generalization to the WKI equation is obtained. Also, starting from the motion of curves, mKdV and its symmetry recursion operator is exhibited explicitly; two- and n-component mKdV systems are obtained. It is shown that WKI systems are gauge equivalent to mKdV systems. The two-component WKI equation admits an infinity number of conservation laws and a recursion formula for the conserved densities is given by considering an eigenvalue problem together with introducing an appropriate transformation.

在二维和三维欧氏空间上，我们从空间曲线运动出发，推导出了mKdV方程以及它的用以生成高阶对称的递归算子；推导出了多元mKdV方程以及二元和多元WKI方程，并证明了WKI系统和mKdV系统的规范等价性；尔后，通过考虑特征值问题，并引入一个恰当变换，给出了二元WKI方程的用以计算无穷多守恒密度的递归公式，从而证明了二元WKI方程的守恒可积性；系统地分析了两种mKdV方程的Painleve性质，并分别给出了两种不同形式的二元和n元mKdV方程的共振点出现的规律。

By the numerical analysis of the ultimate bearing capacity of two- and three-dimensional footing under combined loading mode, the results show that the effect of alteration of underground water lever on bearing capacity of three-dimensional foundation is more than on that of two-dimensional foundation, the effect of soil gravity on bearing capacity of three-dimensional foundation is more than that of two-dimensional foundation. At the same time, the numerical calculation process of ABAQUS indicates that whether the geostatic stress is balanced or not has great effect on the numerical convergence. In view of the effect extent of dilation angle of soil on the ultimate bearing capacity and the failure pattern of foundation, the condition of two-dimensional plane strain is higher than that of the three-dimensional foundation.

复合加载模式下，通过对三维矩形基础和二维条形基础进行数值分析，结果表明：黏性土地基中地下水位的变化，对三维矩形基础极限承载力的影响程度高于对二维条形基础的影响；在求解地基极限承载力的过程中，土体重度对三维矩形基础的影响明显高于对二维条形基础的影响，同时ABAQUS数值计算过程表明，地基土体地应力能否合理平衡，对数值求解过程中是否收敛有很大的影响；就土体剪胀角对地基极限承载力的影响程度而言，二维平面应变情况下土体剪胀角对极限承载力的影响比三维情况下的影响更明显，即土体剪胀角对条形基础极限承载力的影响高于三维矩形基础。

The natural enemies group, neutral arthropod group and phytophagy arthropod group of the two sub-systems were respectively analyzed and have found that all types of arthropods of the two sub-systems can be divided into three different types of groups. The first group is which living in two habitats and the species current is few impacted by the changes of habitats; The second group is which can living in two habitats in turn ,but can transfer to another in the time the habitats was deeply disturbed ;The third one can only living in one habitats and can make the another habitats as a temporary habitats.

Through the comparison of calculation results of two methods in the uniform and the non-uniform inflow, it is found that the results by two methods are very close. The calculation results by two methods are compared with open water test, and the agreement is well. The two methods can both perfectly simulate the hydrodynamics performance of podded propeller, and the method of induced potential needs less program work and can save a great deal of calculation time and memory space. It is a simpler and effective method to calculate hydrodynamics performance of podded propellers and other combined propulsions.

第一次是在市场买了3.3斤的竹蛏，学校有一个公平的平衡，而不是缺乏重量（轻松了手中的规模，小贩都缺乏基本的重量），送往168前4： 30日， LG电子表示，让我内，因此，他走到外面看到168售价海鲜，年轻姑娘走出去的同时，我们买的女子竹外洗（后来知道她的作为年轻的姑娘接近结帐她交出钱），我嫁给了一个奇怪的外观外洗她，没想到看到他们送到清洗和烧伤的全过程，他们的客人的竹蛏购买Taipen在一起，与其他组合，一个又一个的水清洗后，到另一个Dapen个月，然后看看名单重量，您删除一些尺度的两个，这是竹蛏，后客人，因为她是我们的竹蛏，她没有看见我站在后面LG电子，当我们提出异议，她说，数额大致相同，你现在都7月2日， 6日，是两个肠子，好同志， 3.3竹两个她最后与水规模只有两个是2月7日，我们到达胃部，有多少啊！

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。

From distributor's feedback, Areil had gotten sex bribe from DONGGUANG DONGFU two time form Feb to April 2007, our distributor has paid about more than 2400 RMB for his funcking and sex relationship with prostitutors , He had sex relationship with two prostitutors at the same room and at the same time, that called " one fuck two ",that clearlly showed he is a whoremaster and always asked our distributor provide this kind of bribe while he went to field.

客户讲，Areil Concejero 在2007年2月份到4月份期间，曾经2次在东莞接受东莞东福经销商的性贿赂，其中有一次要求客户一次性提供2个妓女供其嫖娼，江湖上说的"一拖二"或者"双飞"就是同时和两个妓女发生性关系，客户总共为他的嫖娼付出2400元的嫖资。可见他是一个贯犯，是个恶劣的嫖客。性质非常恶劣，及其下流，影响非常严重。
