Gaoya dianqi, 2018 传统风偏角的计算模型没有考虑气象因素对空气密度的影响,文中分析了气象因素对风偏角的影响,提出了基于气象的风偏角计算模型,提出了2种分析风偏角与气象要素关系的数学模型。最后通过气象实例数据,对风偏角进行了仿真计算,并用数学模型对风偏角及其影响因素数据进行了建模分析,同时对风偏角进行了预测。结果表明,风速、风向、相对湿度、气压、气温是影响风偏角的主要气象因素,提出的数学模型能较好地分析了风偏角与其影响因素之间的关系,并且具有较高的风偏角预测精度。

Vocabulary Strategy Instruction in the Argentine EFL Context: Teachers’ Perspectives and Practices
International Journal of Applied Linguistics, EarlyView.ABSTRACT Despite extensive research on vocabulary strategy instruction (VSI), little has been known about teachers’ perspectives on how it is understood and implemented in practice. This study investigated Argentinian EFL teachers’ priorities in vocabulary instruction, their perceived knowledge of learner strategies for spoken vocabulary, and factors ...
