Using constant market share( CMS) model,this paper analyzes the export competitiveness of vegetables from China to ASEAN and the main influencing factors. The results show that competitiveness is the main factor in promoting the export growth of vegetables from China to ASEAN,and compared with demand effect and structure effect,competitiveness effect makes the greatest contribution to export growth.展开更多

The main premise of the paper is that effective communication is more than a matter of linguistic proficiency and the learner's pragmatic competence is more or less arrested by the negative cultural transfer from the mother tongue, and based on that premise, the paper analyses the reasons behind negative cultural transfer from the lexical dimension, the speech act dimension, and the psychological dimension, and concludes with a tripartite toolkit of alleviating principles respectively corresponding to the classroom instruction, the teachers, and the students.展开更多
随着高速铁路的不断发展和列车速度的不断提高,高铁场景下车地通信的可靠性和高效性引起广泛关注。列车速度的提升导致更加频繁的越区切换,使系统的可靠性得不到保障,因此列车速度的提升对高铁通信网络的安全性和可靠性产生严重影响。...随着高速铁路的不断发展和列车速度的不断提高,高铁场景下车地通信的可靠性和高效性引起广泛关注。列车速度的提升导致更加频繁的越区切换,使系统的可靠性得不到保障,因此列车速度的提升对高铁通信网络的安全性和可靠性产生严重影响。本文提出1种将LTE-A(Long Term Evolution-Advanced)网络应用到高速铁路场景并基于协同多点传输/接收CoMP(Coordinated Multi-Point transmission/reception)技术的切换优化方案模型,方案参考协作集加入模型。对系统切换成功率等进行性能分析,并与传统切换方案进行性能对比。分析表明:本文基于CoMP的切换方案可有效提升高移动性下网络的切换成功概率,明显改善系统的可靠性和效率。展开更多
