[Objective] The research aimed to simplify the traditional method and gain the method which could directly construct the comprehensive rainstorm intensity formula.[Method] The particle swarm optimization was used to optimize the parameters of uniform comprehensive rainstorm intensity formula in every return period and directly construct the comprehensive rainstorm intensity formula.Moreover,took the comprehensive rainstorm intensity formula which was established by the hourly precipitation data in wuhu City as an example,the calculation result compared with the computed result of traditional method.[Result] The calculation result precision of particle swarm algorithm was higher than the traditional method,and the calculation process was simpler.[Conclusion] The particle swarm algorithm could directly construct the comprehensive rainstorm intensity formula.
Exploitation of Internet potentialities offers a number of advantages in preparing students as oral interpreters. This paper describes how an oral interpretation class makes use of the Internet, suggests a rationale for the various procedures used, and presents case studies which explore the benefits of Internet aided interpretation practice for both students and teachers in pre-class preparation, in-class activity, and follow-up reinforcement. A questionnaire-based survey among 265 English majors also indicates students' enthusiasm and validates the teachers' experiment.
