Finally, we apply the factor analysis of the interest rate risk factors that change the yield curve of bond. Based on the comparison of the static models and stochastic models, we bring forward a dynamic stochastic risk management model of interest rate. In addition to this, we conduct an empirical examination of the management of risk immunized bond portfolios.

用AFLP分子标记技术对 5 0个有代表性的玉米及其野生近缘种大刍草、摩擦禾、薏苡材料进行了遗传关系分析。利用 2 1个PstⅠ MseⅠ引物组合检出可辨认带共 6 4 1条，其中多态性带 5 86条，平均每对引物得到 30 5 2条多态性带，多态性 91 4 %。聚类分析结果表明，可以将 5 0个材料分为 3大类，与已有的玉米族分类一致，但与玉蜀黍属内的种间和种内分类存在差异，说明大刍草各种内存在较大的遗传多样性。本实验发现玉蜀黍属与摩擦禾关系比与薏苡的关系更近，但并没有发现玉米与小颖玉米亚种比与其他大刍草的遗传关系更近。
