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.

Adopt many centres and contrast the test design double and blindly at random, whether to include case (this text choose in the first People's Hospital of Chengdu the case that subcenter collect only ) in according to 3 every...

采用多中心随机双盲对照试验设计，将各中心的纳入病例(本文只选取在成都市第一人民医院这个分中心收集的病例)按照3：1的比例随机分配至试验组和对照组，试验组予以辛夷鼻炎丸口服，每次3克，每日3次，疗程14天；对照组予以鼻舒适片口服，每次5片，3次／日，疗程14天。

Adopt many centres and contrast the test design double and blindly at random, whether to include case (this text choose in the first People's Hospital of Chengdu the case that subcenter collect only ) in according to 3 every centre. The proportion of 1 is distributed to test the group and contrasting the group at random, tests the group and gives the xinyi rhinitis pills and takes orally, 3 grams each time, 3 times a day, the course of treatment is 14 days; Contrast the group to give the bishushi block and take orally, 5 slices each time, 3 times a day, the course of treatment is 14 days.
