We introduce convex,and in particular semidefinite,optimization methods,duality and complexity theory to shed new light to this relation for the single stock problem, given moments of the prices of the underlying assets,we show that we can find best possible bounds on option prices with general payoff funcations efficiently,either algorithmically(solving a semidefinite optimization problem)or in closed form, conversely,given observable option prices,we provide best possible bounds on moments of the prices of the underlying assets,as well as on the prices of the other options on the same asset by sovling linear optimization problems for options that are affected by multiple stocks either directly(the payoff of the option depends on multiple stocks)or indirectly(we have information on correlations between stock prices),we find on-optimal bounds using convex optimization methods,however,we show that it is NP-hard to find best possible bounds in multiple dimensions,we extend our results to incorporate transactions costs,this paper,in theory and practice can provide a reference to researchers and designers about Chinese financial derivative products,the full text is divided into six chapters as follows: ChapterⅠ:Papers on the background and significance of the subjects on a number of option pricing models as well as their advantages and shortcomings of the model and describes the status of research and writing papers and the main contents of the basic idea.

相应地，给定期权价格，也能够出标的资产瞬时价格的最有可能的最好的界。还有通过解决一个线性最优化问题，根据同一标的资产的其他期权的价格来找到这个期权的界值，对于期权受到多种股票价格直接影响(期权的收益依赖于多种股票)或者间接影响(我们有股票之间联系的有用信息)，如果使用凸规划方法我们就会发现没有最优的界，也能够证明对于多维情形确实是很难找到最优的最有可能的界值，最后将这一结论推广到考虑交易成本的情况。本文在理论和实践上给我国金融衍生产品研究者和设计者提供一定的参考。全文共分为六章，具体安排如下：第一章：阐述论文的选题背景和意义，介绍期权定价的一些模型以及这些模型的优点与缺点，并介绍国内外研究的现状以及论文的写作基本思路与主要内容。

At least, that's what I understood by the remark and I think that it is valid.

Although this is meant,should browse by tens of thousands mailbox address, but this kind of painstaking work is necessary really, because,this is: You can be clear about 1 your user people can choose what mailbox, will adopt a few measure to avoid to be regarded as with this rubbish mail is deleted directly, what perhaps differ according to each mailbox is characteristic, will be behaved more markedly. 2 if what a few people use is company mailbox, then you can understand the trade that they pursue roughly, will provide the service that has specific aim more with this. 3 can correct a few apparent spelling mistake. If 4 has a competitor jumbly inside, can will delete.

尽管这意味着要浏览成千上万的邮箱地址，但是这种费力的工作确实是必要的，这是因为：1你会清楚你的用户们会选择哪些邮箱，以此来采取一些措施避免被当作垃圾邮件直接删除，或者是根据各个邮箱不同的特性，来表现得更为醒目。2如果一些人使用的是公司邮箱，那你就能大致了解他们所从事的行业，以此来提供更有针对性的服务。3能够修正一些明显的拼写错误。4如果有竞争对手混杂在里面，可以将之删除。

But in practical operating, overvoltage caused by reignition of the vacuum switching device frequently appears, and it result in damage of the capacitor bank or the switchgear itself. Ensuring the switchgear against reignition and installing a protective device are two main approaches to avoid the phenomenon. In this paper, a study on overvoltage caused by reignition due to capacitor bank switching with the vacuum switching device and its preventive measures are carried out. The main work which has been done and researches are as follows: 1. The producing mechanism of overvoltage and its influence factor are analyzed. It is pointed out that single-phase reignition is the main reason for damage of the switchgear and two-phase reignition is the main reason for damage of the capacitor bank,so overvoltage of single-phase reignition and two-phase reignition are the emphases of prevention. 2. Analysis of the special working condition of the operating switch for capacitor bank is carried out. It indicates that the vacuum switching device is difficult to realize no-reignition under this operation condition, so it is more practical to adopt protection devices. 3. Analyses of protection effect of RC and MOA and their shortages are carried out. It shows that the two methods can only restrain effectively overvoltage caused by single-phase reignition, and they cannot protect the capacitor bank when reignition of two-phase occurs. 4. The operation principle of G-R damping device is analyzed and discussed emphatically.

本文针对真空开关投切电容器组时因重燃而产生的过电压及其防治措施进行了研究，所开展的主要工作和研究结果如下： 1、对过电压的产生机理及其影响因素进行了分析，指出单相重燃是导致开关设备损坏的主要原因，而两相重燃则是导致电容器组损坏的主要原因，因此单相重燃和两相重燃过电压是防护的重点； 2、对电容器组操作开关的特殊运行条件进行了分析，指出在这种运行条件真空开关难于实现不重燃，因此采用保护装置更具有现实意义； 3、对RC与MOA的保护效果和存在的不足进行了分析，指出这两种方法均只能有效抑制单相重燃过电压，而不能在发生两相重燃时保护电容器组； 4、重点对G-R阻尼装置的工作原理进行了分析和讨论，指出该装置接入后线路中将会出现两种频率的高频振荡，而电容器组上的过电压是由这两种振荡共同决定的； 5、根据对上述两种振荡的分析指出存在一个最佳电阻值使得过电压最低，并提出了电容器组电压和最佳电阻值的近似求解方法； 6、使用电气暂态分析软件MATLAB对G-R装置的保护效果进行了仿真计算，证实该装置确实可以有效抑制重燃时的电容器组过电压； 7、根据仿真与近似计算结果的偏差提出了近似计算的修正方法，经过修正后的过电压计算结果与仿真结果吻合较好； 8、对G-R装置中放电装置G与阻尼电阻R的要求进行了分析，指出采用编织电阻和真空间隙可能是最佳选择。

"Well I think we have a corporate responsibility but also customers are actually interested to lower their fuel bills and increasingly we see that taxation is based on CO2, so to keep the motoring cost low we need to get on the band wagon."

我觉得我们公司有责任，顾客也确实希望能减低油费，而且课税是根据二氧化碳，所以为了降低汽车的花费，我们需要跟上潮流。

For example, when meeting customers who are not contented with the food, if the employee thinks the guest has reason to be discontented, he has the right to let them eating for free. And if guest is not satisfied with the service, the employee can make a certain derating or give him some presents and so on based on the reasonable fact.

在餐厅里遇到顾客对饭菜不满意时，如果员工觉得客人确实有理由不满意，那么他有权决定是否给客人免单；如果客人对客房服务感到不满意，那么员工也可以根据实际情况给予一定的减免或者送一些礼物等。

There indeed are an abundant amount of anonymous ad hominem attacks from kobe lovers who don't corroborate their opinions, but if you ignore those and look at the rational posts, you'd understand too why the author's piece is also an unsubstantiated, undeveloped, and dishonest analysis- the only difference between the author's article and these anonymous posts you refer to is that the author's is 10 times longer and without the invectives.

这确实有很多匿名的带个人偏好色彩的攻击，这些言论来自科比的拥护者们，他们并不能说清自己的观点，但是如果你跳过这些去看那些理性的发言，你会明白为什么那个作者的文章是如此的五根据，未开化和分析多么不诚实——也许在作者和那些你所说匿名发言的的区别就在于，作者的言论是10倍的长，并且没有恶言。
