| 摘 要： | 首先建立了一类具有时滞的金融模型, 该模型以累计利润额为关键因素, 接着以τ为参考元素研究了该模型的稳定性及Hopf 分叉. 发现当τ变化时, 该系统的稳定性会发生变化， 该模型会在某一确定值处出现Hopf 分叉. 最后用中心流形定理和规范型方法研究分叉周期解的稳定性.

| Abstract: | The study of the Harbin Airport Thunderstorm Analyzing and Forecasting System made full use of the existing meteorological equipments and a variety of high-level programming languages, for example: it can reading and analyzing the initial data automatically by using the meteorological information network, discriminating the thunderstorm weather situation automatically by using the analog discriminatory analysis method, issuing the 0-24h thunderstorm probability prediction which weights the established weather forecast model by using the synoptic forecasting and mathematical statistics method, issuing the 0-1h thunderstorm nowcasting and warning by using the cross-correlation method based on weather radar echoes. The application shows that the system operation and nowcasing and warning are achieved the desired effect. |
