简介:摘要随着社会经济、电子技术、人工智能的快速发展以及在高等教育国际化大背景下,21世纪社会对人才结构的需求也发生了新的变化。发展复合型、应用型人才是推进国家教育现代化的迫切需要。近几年,各高校泰语专业纷纷推出“语言+专业”以及“专业+语言”的人才培养模式。但是在现实实践中确实很难平衡和发展,仅仅是采用整合本校专业资源,语言与专业分离授课的方式,语言基础知识由语言老师完成,专业知识由专业教师以中文讲授的方式来推进,而这种做法有违背了语言作为载体应该与所承载信息一同输出输入的自然属性,实践证明了所培养出来的人才“小才济济,大才需缺”以及学生无法将两者联系起来,最后导致语言薄弱,专业不扎实的现象。本文结合我校泰语专业十余年的人才培养模式,经验总结,初探“语言专业+合作教育(Co-OPE)的人才培养模式,旨在培养出真正能用的复合型、应用型泰语人才,为“一带一路”战略提供服务的高端人才。本文通过采用质化的研究方法,文献综述初探“语言专业+合作教育(Co-OPE)的人才培养模式在泰语专业培养复合型人才以及应用型人才提出建设性意见。

简介:摘要本文选取常规观测资料、自动站资料以及NCEP再分析资料等相关资料,对2016年7月2-4日如皋市暴雨天气成因进行分析。结果表明本次暴雨天气主要是由于副热带高压稳定少动、低涡东移和西南暖湿气流共同作用下产生的。本次暴雨天气的水汽输送通道主要是由副热带高压西侧所产生的偏南气流,持续将来自南海以及孟加拉湾海的水汽朝华东输送,同时在强降水落区上游构成很强的水汽辐合,为此次暴雨天气的发生发展提供了有利的水汽条件。低层辐合,高层辐散的抽吸作用对于上升运动的产生以及维持较为有利,为暴雨天气的发生发展给予了较好的动力条件。在本次暴雨天气过程中,K指数始终维超过35℃,大气呈现出特别不稳定的状态。SI指数的分布具有显著的日变化。如皋市呈现出“中高层干、低层湿”的形势,高温高湿的环境形成热力不稳定条件,促使暴雨天气的产生。
