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。

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.

在分布和波动相关性建模方面，本文利用ARCH-M族模型来模拟我国股市和成熟证券市场的收益序列，以揭示股票市场中投资收益与时变风险的关系，并对我国股市和成熟市场的风险补偿系数以及投资者风险承受能力进行比较研究。

This puts forward the research hypothesis requiring empirical test of large sample further.

并进一步提出了有待大样本实证检验的研究假设。

The Si/Al ratio of NaY molecular sieve was determined by an empirical formula of lattice constant obtained by extension function method of X-ray diffraction and framework Si/Al ratio of NaY molecular sieve determined by solid nuclear magnetic resonant spectrum method.

前言晶胞参数是决定晶体结构的重要参数之一，Na Y超稳分子筛属立方晶系，由于 Na Y超稳分子筛骨架硅铝比受许多条件的影响，如投料比、晶化温度、晶化压力和晶化时间等。通过研究发现分子筛骨架的硅铝比与其晶胞参数相关，而分子筛的硅铝比可作为合成分子筛产品质量的控制指标 [1] 。

This result reinforced Lavoisier's findings in 1772 when he discovered that both phosphorus and sulfur when burned increase in weight (section 25.5) When an anomaly (potential empirical falsification) arises, something must be done.

该结果强化了拉瓦锡在1772年的发现：那时，他发现磷和硫在燃烧中其重量是增加的（第25.5节）。当出现异象的时候，则必须采取措施。

It should be kept in mind that here,as elsewhere in his work,Weber was describing pure types;he was aware that in empirical reality mixtures will be found in the legitimation of authority.

必须留意的是这里，一如韦伯作品的任何地方，他描述了一种至纯的形式，他认识到靠经验得来的一系列事实可以在被定为合法的权威中找到。

The theory of weighted empirical processes is an important element for nonparametric likelihood ratio goodness of fit test.

在讨论非参数似然比拟合优度检验时，加权经验过程理论是一个非常重要的基础。

The purpose of the paper is to develop an empirical Bayes process monitoring technique for manufacturing categorical data utilizing the likelihood ratio method.
