A new crossover operator is proposed to keep goad genes and enhance the search performance. Local search mechanism is added into GA to find solutions for TA problems with a more rapid convergence speed. Simulated annealing is used to overcome the problem of local optimum. A heuristically greedy local search is also proposed to improve the search efficiency. The simulation results show that the improved algorithm can improve the search efficiency of GA.

构造了适合于目标分配问题的染色体；设计了搜索性能较好且能够保留优秀基因的交叉操作方法；将局部搜索机制引入标准遗传算法，提高了目标分配算法的收敛速度；把模拟退火算法引入局部搜索问题，在一定程度上避免了局部最优问题；将贪婪算法应用于局部搜索提高了最优分配方案的搜索效率。

World-reknowned naturopathic physician Dr. Theresa Dale explains that, no matter what your age, your body already knows how to produce optimal amounts of hormones—it's all a matter of stimulating it to do so.

世界知名的自然疗法医师Theresa Dale博士解释说，无论你的年龄是多少，你的身体自己知道怎样分泌最适合的荷尔蒙数量----它取决於刺激的程度。

And as different degrees of industry were apt to give men possessions in different proportions, so this invention of money gave them the opportunity to continue and enlarge them: for supposing an island, separate from all possible commerce with the rest of the world, wherein there were but an hundred families, but there were sheep, horses and cows, with other useful animals, wholesome fruits, and land enough for corn for a hundred thousand times as many, but nothing in the island, either because of its commonness, or perishableness, fit to supply the place of money; what reason could any one have there to enlarge his possessions beyond the use of his family, and a plentiful supply to its consumption, either in what their own industry produced, or they could barter for like perishable, useful commodities, with others?

就像不同程度的勤劳会给人们不同数量的财产，货币的发明也给予了他们机会去保存和扩大货币。想象有这么一个岛屿，与世界其它地方的贸易完全隔绝，在那里只有一百户家庭，但是有绵羊，马和奶牛，和其它一些有用的兽禽和有益健康的果实，以及足够生产十万倍谷物的土地，可是，由于这些物品不是太过普遍就是易于腐烂，岛上竟没有一样东西适合做货币；在这种情况下，那里的任何人在超过他的家庭所需，以及通过自身的劳动生产或与他人物物交换一些类似的易腐的有用的日用品之外又有什么理性去扩充他的财产呢？

Through a series of quenching, tempering, tensile testing, low-temperature impact test and metallographic analysis, we ultimately came to the following conclusions:(1) low-carbon alloyed steel 20CrMn2NiMoV quenching at 870℃ and tempering at 200℃, whose structure contains tempered dislocation lath martensite and few small bainite under mixed, has the best obdurability;(2) Carbon Steel 45CrMn2NiMoV quenching at 850℃ and tempering at 620℃, whose structure is sorbitic, has a performance less than that of low-carbon Alloyed steel, but it can also meet the basic design requirements.(3) Mn can substitute for the role of Ni within limited extent.

通过一系列淬火、回火、拉伸试验、低温冲击试验以及金相分析，最终得出以下主要结论：（1）低碳合金钢20CrMn2NiMoV经870℃淬火+200℃回火，得到回火位错型板条马氏体+少量细小下贝氏体的混合组织，具有最佳的强韧性配合；（2）中碳合金钢45CrMn2NiMoV经850℃淬火+620℃回火，得到回火索氏体组织，综合性能虽然不及低碳合金钢，但也能基本满足设计要求；（3）Mn在一定程度上能够替代Ni的作用，适量的Mn和Ni相互配合可以得到最佳的低温韧性，因此&以Mn代Ni&是低温钢材料研究开发中一条可行的适合我国资源状况的合金化思路。

Therefore, it can be regarded as a great improvement of the investment decision-making theory and methods .This article makes a systematic research on real options theory and method and its application, including the following several main aspects:Firstly, it makes a detailed discussion about the common theoretical basis of financial options and real options, including no-arbitrage equilibrium principle, risk-neutral definition, complete market and dynamic tracking.Secondly, it analyze three basic characteristic of investment decision-making in modern market economic system: irreversibility, uncertainty and flexibility, and from the angle of their mutual quantitative and qualitative interactions, it makes a comparison between the traditional NPV methods and real options methods and makes a summary of the general analytical methods of real options.Thirdly, it discusses the all elements in the application of real options such as the ^leakages in value of real assets, basis risk, and private risk, and furthermore, it attempts to put forth a normalized strategy of its application and construct a basic framework of its application.Fourthly, it applies real options theory to strategetic investment of enterprises and the buy-out of company, putting forth a value model for strategetic investment program and making a concrete analysis of its application to buy-out. Furthermore, it advocates that a flexible investment decision-making system should be setup according to real options theory in our country.

本文对实物期权理论和方法及其应用进行了系统研究，主要内容包括如下几个方面：(1)详细讨论了金融期权和实物期权共同的理论基础，主要包括无套利均衡原理、风险中性定义、完全市场以及动态复制方法，对这些理论方法的探讨既是本文的出发点和基础，它们提供了研究实际应用实物期权的一个基准点，也是贯穿全文的线索和灵魂；(2)分析了现代市场经济体系中投资决策的三个基本特征即不可逆性、不确定性和时机选择，并从它们数量上和质量上相互作用的重要意义的角度，分析了传统的净现值法与实物期权方法的差异，指出了净现值法在不确定环境中存在的缺陷及实物期权处理投资灵活性的价值，并将净现值法纳入实物期权投资分析决策体系当中，总结了企业投资决策实物期权的一般分析方法；(3)探讨了实物期权应用中要考虑的各种要素，如实物资产的价值漏损、基差风险和非市场风险等，并进一步提出了实物期权应用的规范化策略和构建了一个实际应用实物期权方法的基本框架，尝试将期权的基本原理与企业在现实经济环境中投资决策的要素结合起来，从而可以在一定程度上超越期权的复杂的数学计算而汲取期权思想的精华，从而促进期权决策方法在实际投资决策中的应用；(4)将实物期权方法应用于企业战略投资，得出了战略投资项目的价值模型，指出可以将实物期权理论和方法应用于企业并购，分析了应用的具体方面，并提出应根据实物期权理论建立一套适合我国企业的灵活的投资决策系统。
