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。

The hypermethylation of 5 CpG in promoter region serves as a mechanism of the inactivation of RASSF1A gene. This mechanism has been widely confirmed in multiple tumorgenesis including prostate carcinoma cell line DU145. Object Our study is to disclose the epigenic mechanism of the carcinogenesis of prostate cancer. Including: 1. We use demethylation agents in combination with chemotherapeutic drugs, to disclose whether demethylation agents can enhance the anticancer effect of chemotherapeutic drugs. 2. to study whether demethylation drugs can affect the methylation level of RASSF1A gene in.
目的 本研究旨在探讨前列腺癌的表遗传学发生发展机制,包括: 1、甲基化抑制剂与多种化疗药物联合应用,探讨二者间的协同作用,增强化疗药物疗效; 2、体外应用甲基化抑制剂对前列腺癌细胞DU145的RASSF1A基因甲基化水平的影响; 3、体外应用甲基化抑制剂对前列腺癌细胞DU145的RASSF1A基因及蛋白表达的影响,以期为进一步深入探索通过改变抑癌基因的甲基化而为前列腺癌发生机制和基因治疗提供有意义的数据和理论依据。

And the scientific research showed that they are medicable to insomnia, anxiety and other diseases that found in modern people. 4 The regression models of biomass were used to calculate the total cumulative biomass. Average biomass of six samples was 62.88 t·hm-2 after cutting 3 years, which was higher than that of tropical secondary forests with 5 years succession. It can be concluded that traditional fuel woods had played an important role in conservation of tropical forest in the area. Caloric values were not different in major fuel species (Coefficient of variation was only 1.1%). The similar result was found in stems of C. siamea after growing different years. The main reason of C. siamea cultivation was that it had the character of hardwood, easy collecting, little ash, and so on.
铁刀木的各个部位都作药用,资源量大的树叶和心材使用最多,并且现有的研究成果表明它们具有多种活性成分,针对现代人常患的失眠、焦虑等疾病具有较好疗效。4)通过收获法拟合的生物量回归模型对推测西双版纳地区铁刀木林薪柴蓄积量有较高的参考价值,砍伐3年后的六个样方中铁刀木的平均生物量为62.878 t.hm-2,高于5年林龄的热带次生林(16.35t·hm-2),对西双版纳热带雨林的保护有着重要意义。5)几个村寨最主要的薪材树种热值研究结果变异系数仅为1.1%,各薪材树种之间热值相差不大,铁刀木被选择为传统薪炭林更多是因为材质坚硬、收获运输方便、燃烧完全等特点。

Moreover, supersensitization as well as its mechanism by stabilizers is studied in spectral-sensitized AgCl emulsion Results indicate that the adding order of stabilizer and sensitizing dye has great influence on the sensitivity of emulsion and only stabilizer added after sensitizing dye can supersensitization be obtained Apart from supersensitization and fog-inhibition by stabilizers, it is also significant to spread the amount of addition of dye, which can lead the further improvement of sensitivity of emulsion.
本文还研究了稳定剂在氯化银乳剂中的超增感作用并应用多种手段研究了其超增感作用机理。结果说明,稳定剂与增感染料的添加次序对乳剂感光度有非常重要的影响,只有在增感染料之后加才可能产生增感作用。在一定的稳定剂添加范围内,它不仅可以提高氯化银乳剂的感光度、降低灰雾,而且还能加大增感染料的用量,进一步提高乳剂的感光度。这对乳剂的光谱增感来说具有重要意义。
