在“融语文”教学中拓展延伸文本

"融语文"阅读教学以语文教科书为蓝本,建构跨领域的学习内容,采用多元化的语文阅读方法、手段、策略、路径等,全面发展和提升学生的语文素养。通过对读者经验的融入、作者经验的融入以及相关文本的融入,突破了传统的以单篇为主的语文教学低效格局。"融语文"阅读教学,让学生对语文文本有了更为清晰、更为广阔、更为全面、更为深刻的认知,因而提升了学生的语文学习力,发展了学生的语文核心素养。

基于核心素养的“融语文”教学主张与校本建构

本文对基于核心素养的"融语文"教学主张与校本构建进行了简单分析和研究,明确了核心素养与"融语文"教学主张的含义,并在结合实际教学现状的基础上,合理制定了的实施对策,希望可以为提升小学语文教学水平提供依据。

Culture fusion and English language teaching

This paper is first to exemplify the problems caused by culture difference. After this, a survey is made on Chinese-western culture difference and its main aspects, followed by the Chinese and western culture difference on the layer of language. In the second part the discussion of the relationship between language and culture reveals the importance of culture education in language teaching. The author is of the opinion that one cannot really master a target language without adequate knowledge of the culture related to that language. The paper concludes with several suggestions about useful ways to get culture fusion in ELT and points out that human beings do not live in the objective world alone, nor alone in the world of social activity as ordinarily understood but are very much at the mercy of the particular language which has become the medium of expression for their society. It is quite an illusion that language is merely an incidental means of solving specific problems of communication or reflection.

基于UKF的雷达和机载ESM扩维跟踪

为有效提高异类传感器融合跟踪的效果,提出了一种基于UKF的雷达和机载ESM扩维跟踪算法。首先将目标和机载ESM的状态信息组合起来,形成一个高维的状态向量,从而有效抑制滤波中GPS定位误差所带来的影响;接着在此基础上采用UKF来实现目标的定位跟踪,以求进一步减小扩维后线性化误差加大等问题的影响。仿真结果表明,该算法可更好地实现对目标的定位跟踪。
