通过比较北美海蓬子和盐城海蓬子在生长条件和营养成分的差异，发现北美海蓬子引种盐城滩涂后，虽然由于气候、土壤等条件发生了变化使其栽培条件和各营养成分的含量发生了一定的变化，但是其主要营养分组成却没有变化，而且改良后的品种某些营养素的含量得到了提高。

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.
