In this paper we assume the expected returns of the risky and risk-free assets as well as the covariance matrix of the risky assets are not exactly known, but defined by some known elements, which form the vertices of this polytope. Robust optimal portfolio problems are proposed in the market with and without risk-free asset. And the analytical solutions are given out when the covariance matrix of the risky assets are exactly known.

本文假设风险资产和无风险资产的收益以及风险资产的协方差矩阵不是完全确定的，其相关参数属于某个已知的凸多面体，分别在市场不存在和存在无风险资产的情况下定义了稳健最优投资组合问题，并在协方差矩阵确定的情况下给出了问题的解析解。

The shrewder of the two birds watching the Concorde fly by likens it to a Tyrannosaurusrex, the favorite di-nosaur of countless little boys around the world. In reality, by the way, few birds would sit gazing at the Concorde thundering past; the roar it makes at low altitudes would have them fleeing for their lives.

画中两只鸟正看着一架协和飞机从头顶上飞过，其中一只精明的鸟将它比作霸王龙———世界各地无数小男孩喜欢的一种恐龙（顺便说一句，实际上没有哪只鸟会落在树上凝视协和飞机发出雷鸣般的轰鸣飞过，这种在低空的轰鸣早就把它们吓跑了）。

The results indicate that the effect of CA-FCM using rainfall and atmospheric perceivable water as covariants is better,for the physical covariant that is not influenced by catalyze is used as controlling factor and cluster analysis method is employed.The significant is more than 0.05.The effects of other methods are worse.

结果表明：协变量由降水量和整层大气降水量2个组成的CA-FCM方法，由于引入了不受催化影响的物理协变量作为控制因子，以及采用了聚类分析提高了对比区和影响区相关性，其评估效果最好，显著水平高于0.05；其他评估方法评估效果较差。
