The mechanism of photosensitivity and phototaxis was studied with optical andelectrophysiological method. The results are as follows:1 among three kinds of Chysopa peral. of the compound eyes show little daily change in Chrysopa sinica Tjedar .The model and color of psesudpopupil show significant daily change in Chrysopa septempzhbybimctata Wesmacl and Chrysopa formosa Brauer, color and diameter of the psesudpopupil of the compound eyes in Chrysopa septempunctata Wesmacl make rapid change at noon, afternoon ,night are similar ,but make little change in the morning and the next morning. Diameter of psesudpopupil of compound eyes is the biggest in the afternoon, which of Chrysopa formosa Brauer, is the biggest at noon.

本文应用光学及电生理学方法对棉铃虫优势种天敌—中华草蛉、大草蛉和丽草蛉3种草蛉的感光和趋光机制进行了研究，主要研究结果如下： 1、中华草蛉、大草蛉、丽草蛉复眼伪瞳孔大小、颜色昼夜间有节律性变化，且种间具有不同的变化模式。3种草蛉中，中华草蛉复伪瞳孔大小昼夜节律变化不明显，其模式和颜色上亦基本无变化，中间为一小黑点，其外围是绿色，最外层为红色，形状为正六边形：大草蛉、丽草蛉的复眼伪瞳孔大小昼夜间不同，大草蛉的复眼伪瞳孔在中午、下午、晚上变大，早晨和次日早晨基本一致，但次日早晨稍小些。

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。
