谈义乌市公示语的英译

良好的国际化语言环境是国际化城市建设的保证。义鸟市公示语英译还存在着浮于表面的解读、选词欠地道、简单的字字对应、不规范的书写等不足。针对这些问题，建议采取建立行政管理机构、推行翻译人员持证上岗制度、加强公众舆论监督等具体措施。     

MATLAB在电气工程专业主干课程教学中的应用

电气工程及其自动化本科专业主干课程具有非常强的理论性、实践性和应用性,本项目研究将MATLAB仿真技术引入到专业课程的课堂教学和实验教学中,使抽象难懂的知识"活"起来,有效降低理解的难度,较大程度提高了学生的学习趣味性、积极性和主动性。     

MATLAB在地球物理专业《磁法勘探》课程教学中的应用

《磁法勘探》是一门理论性和实践性较强的地球物理专业课程。由于课程内容抽象,不易理解,如果仅通过理论课程很难系统地认识磁法勘探和数据处理过程,所以本研究将计算机软件MATLAB融入本课程教学中,不仅加深学生对理论知识的理解,更能培养学生编写代码、数据处理和解决实际问题的能力。

Random vibration analysis of switching apparatus based on Monte Carlo method

The performance in vibration environment of switching apparatus containing mechanical contact is an important element when judging the apparatus’s reliability. A piecewise linear two-degrees-of-freedom mathematical model considering contact loss was built in this work, and the vibration performance of the model under random external Gaussian white noise excitation was investigated by using Monte Carlo simulation in Matlab/Simulink. Simulation showed that the spectral content and statistical characters of the contact force coincided strongly with reality. The random vibration character of the contact system was solved using time (numerical) domain simulation in this paper. Conclusions reached here are of great importance for reliability design of switching apparatus.     

水稻免耕栽培生理基础——Ⅱ.免耕水稻的光合特性

威优64、陆青早1号作为试验材料,免耕能提高功能叶的光合速率、生育前期功能叶的呼吸强度、绿叶面积、叶绿素和可溶性蛋白含量,并延缓它们在生育后期的下降速率,降低后期功能叶的呼吸速率。主分量分析说明,在研究光合作用时,光合强度、叶绿素、可溶性蛋白质、叶片含氮量,可以任意选择一个作为光合特性指际。粒/叶比说明,免耕对源的改善较对库的改善较好些。

Paired peer learning through engineering education outreach

ABSTRACT

Undergraduate education incorporating active learning and vicarious experience through education outreach presents a critical opportunity to influence future engineering teaching and practice capabilities. Engineering education outreach activities have been shown to have multiple benefits; increasing interest and engagement with science and engineering for school children, providing teachers with expert contributions to engineering subject knowledge, and developing professional generic skills for engineers such as communication and teamwork. This pilot intervention paired 10 pre-service teachers and 11 student engineers to enact engineering outreach in primary schools, reaching 269 children. A longitudinal mixed methods design was employed to measure change in attitudes and Education Outreach Self-Efficacy in student engineers; alongside attitudes, Teaching Engineering Self-Efficacy and Engineering Subject Knowledge Confidence in pre-service teachers. Highly significant improvements were noted in the pre-service teachers’ confidence and self-efficacy, while both the teachers and engineers qualitatively described benefits arising from the paired peer mentor model.
