To overcome the problem of limited market data on forward credit spread quotes, and to increase the accuracy in estimation, we propose a multinomial tree model in this paper and apply it on both European and Bermudan CDSwaptions.

相较过去文献上建构多元树必须配适标的资产对数报酬率之分配的多阶动差，本文建构多元树的方法仅需配适较少的动差，即可建构出任意分枝个数的多元树模型。

The bottle tree, plump and leathery at its base, tapers to a sprout of twisting, hand-like little branches clutching bouquets of pink flowers.

圆鼓鼓的瓶树基部似皮革，向上逐渐变细，最后生出扭曲的细枝，形似手，紧紧抓着开出的一束束粉花。

To speed up the solution of the problem, a solution method that hybridizes heuristic algorithm with conventional branch and bound method is presented.

文中还讨论了采用启发式算法同传统的分枝定界法相结合以提高问题的求解速度，并给出了一个数值例子。

Moreover, if the optimization problem has certain special feature, the simpler relaxation methods can be provided. For example, considering a generalized geometric programming problem, relevant relaxation linear programming can be obtained using its special structure. Based on the branch and bound method, a linear relaxation algorithm of global optimization is presented for generalized geometric programming, and the convergence of the algorithm is also proven.

此外，当优化问题具有某种特殊性质时，我们能给出更加简便的松弛化方法，如考虑广义几何规划问题，能充分利用其特殊结构，建立了广义几何规划问题的松弛线性规划问题；在分枝定界技术的基础上，提出了一个求广义几何规划全局解的线性松弛算法；证明了算法的收敛性。

An advanced branch and bound method which reduces the computer resolving time enormously and leads the reliability research of large-scale spatial frame structural systems close to practical use is presented on condition that the same computation accuracy is ensured.

导出了大型空间刚架结构系统某梁元断面达到塑性屈服极限时的修正刚度矩阵和相应的等效节点力向量；提出了在保证同等计算精度的条件下，可成倍地减少运算时间的改进分枝限界方法，使大型空间刚架结构系统的可靠性研究向实用化迈进；本文开发出可自动生成失效衡准，自动选择主要失效形式，追踪失效过程的计算机程序。

I examed one of the pen closely and it looked certainly genuie.at the base of the gold cap,the words of 'made in america' was neatly inscribed.the man said that the pen was worth 50 pounds, but as a special favor he would like me have it for 3o pounds, i shaked my head and held up my five fingers indicating that i was willing to pay 5 pounds.gesticulating widely it is as if my offer outrageous,but he eventually ruduced the price to 10 pounds.shrugging my shoulds,i began to walk away .when a moment later,he run after me and thrusted the pen into my hands.though he kept throwing up his arms in despair, he readily accepted the price i gave him.i felt especially pleased with my wonderful bargarn until i got back in the ship.

我仔细察看了一枝钢笔，那看上去确实不假，金笔帽下方整齐地刻有&美国制造&字样。那人说那支笔值50英镑，作为特别优惠，他愿意让我出30英镑成交。我摇摇头，伸出5根手指表示我只愿出5镑钱。那人激动地打着手势，仿佛我的出价使他不能容忍。但他终于把价钱降到了10英镑。我耸耸肩膀掉头走开了。一会儿，他突然从后追了上来，把笔塞到我手里。虽然他绝望地举起双手，但他毫不迟疑地收下了我付给他的5镑钱。在回到船上之前，我一直为我的绝妙的讨价还价而洋洋得意。

By splicing in genes from other bugs, the company was able to engineer synthetic metabolic pathways—ones that do not exist in nature—that enable the bacteria to produce isoprene from the sugars found in plant materials such as sugar cane, corn cobs and switchgrass, a tall-growing variety native to North America.

Genencor的科学家们通过将大肠杆菌的基因与其它菌类基因接合，则能研发出前所未有的代谢合成途径，使细菌能从植物所含的糖类中制造出异戊二烯，这些含糖植物包括甘蔗、玉米棒和北美特有的变异品种柳枝稷等。
