In the second section, we describe two novel species that were isolated from the Chigu and Szutsao saltern. On the basis of phenotypic, phylogenetic and genetic analyses, these two strains were considered to represent a novel species of the genus Virgibacillus and Marinobacter, and were named Virgibacillus chiguensis and Marinobacter szutsaonensis according to Chigu and Szutsao saltern.

本研究亦从盐田分离出两株极端耐盐菌，经由型态、生理、生化及分子演化等多重分析比对，确认这两株菌株为新菌种，分别依其分离之盐田命名为七股菌与四草菌，并寄存於菌种保存研究中心。

Five ways on comparing covariance matrix are applied to the Shanghai 50 Indexes Stock Exchange, which are sample covariance matrix, scalar matrix, two-parameter covariance matrix, single index matrix, constant correlation matrix. We adopt principal components method and Markowitz portfolio method to measure stock market risk using VaR, getting the effect of measuring market risk. The result shows that sample covariance matrix and two-parameter covariance matrix could measure market risk more effectively.

本文以上证50指数数据为样本，采用样本协方差矩阵、数量矩阵、两参数模型矩阵、单指数模型矩阵、常量相关矩阵作为与股票相关的协方差矩阵，结合投资策略选择的主成分方法和Markowitz最优投资组合方法，计算VaR以度量市场风险，并比较了五种协方差矩阵度量市场风险的效果，结果表明，在主成分方法中，样本协方差矩阵和两参数矩阵方法能有效的度量市场风险。

Owing to the possible measurement error of variance and covariance for Markowitz's M-V model, in the present study, it employs two static models and two dynamic models, which are the sample covariance model, implicit factor mode!, implicit factor GARCH model and full-factor multivariate GARCH model.

基於Markowitz(1952)提出的M-V投资组合模型可能造成变异数及共变异数衡量的偏误，因此，本文以样本共变异数模型、内含因素模型等两我种静态模型，并参酌Alexander and Leigh(1997)的内含因子GARCH模型与Vrontos et al。
