A systematic study of correlation between nose disturbances and evoluted behaviors of asymmetric vortices over slender body models has been conducted. The new flow phenomena have been revealed in which the two-cycle behavior of Cy vs.γ curve for asymmetric vortices flow is continuously changed into one-cycle behavior with increasing of disturbance strength on the model nose tip. This newly found flow phenomenon is important and it provides a physical flow base to the perturbation active control of forebody asymmetric vortices flow.

Since Leptokurtosis, skewness and fat-tail are always used to depict market risk, this paper introduces the improved Laplace distribution to risk management of stock portfolio. Empirical results show, improved Laplace distribution and asymmetric Laplace distribution are similar for estimating Leptokurtosis, while improved Laplace distribution is better for estimating skewness.In order to analyze the correlation between return distribution and volatility, the thesis uses ARCH-M Models to simulate the return series of China's Stock Market and developed markets ao as to discover the relation between investment return and time-varying risk.

对尖峰、厚尾、偏态的刻画有助于正确估计市场风险，本文将改进型Laplace分布引入到股票组合的风险管理中，实证结果发现，改进型Laplace分布和非对称Laplace分布对尖峰、厚尾的刻画效果接近；而非对称Laplace分布对负偏性考察不足，改进型Laplace分布的拟合结果能够准确地反映股指收益的负偏态，这也正是改进型Laplace分布相对于传统的非对称Laplace分布的优势所在。
