On the introduction of the theorem, structure and optoelectronic digital implementation of PSNN, construct perfect shuffle type of interpattern association model applying IPA algorithm, simplifying the descriptions of both the interconnecting weight matrix and the patterns which makes it a more"optical"model. The associating capability is improved regarding to the classical IPA with advanced noise immunity and robustness, which further authenticates PS-IPA a desirable model for ONNs' study.(2) Generalize PSNN to α-shuffle type of neural networks to extend and optimize shuffle networks' applications.

第二部分以洗牌型光学神经网络的探讨为主题：（1）基于洗牌型光学神经网络的基本思想、构造原理和数字光电实现的特点，应用IPA算法构造了洗牌型图样间联想模型，使互连权矩阵和样本的描述更为简洁，更赋光学模型特色，并改善了原IPA模型的联想功能，识别抗噪性和鲁棒性都大有提高，从而可以作为ONN研究的理想模板。

In the empirical analysis part, statistical descriptions on the sample funds are made firstly, which show that the actual distribution of each sample fund"s daily net value return possesses the characteristic of leptokurtosis. So it is necessary to add student T distribution and GED to capture such leptokurtosis characteristic other than normal distribution. Secondly, ARCH test shows that there exists volatility clustering in each sample fund"s daily net value return, so GARCH related models should be used to describe such volatility clustering characteristic.

实证分析部分首先对样本基金进行统计描述，得出其收益序列均存在尖峰厚尾特征，不服从正态分布，因此有必要在下面的VaR计算中加入T分布和GED分布来捕捉这种尖峰厚尾特征；并且经ARCH检验后得出收益序列存在明显的波动聚集性的特征，因此可以选择GARCH类模型来描述这种特性，经过模型筛选，得出最适合我国开放式股票型基金的收益波动性模型为GARCH(1，1)模型。
