Chinese Journal of Applied Linguistics 2003年第3期26卷 38-44,127页

作者：张军甘肃教育学院(新加坡)南洋理工大学

In view of current advocacy of the Communicative Language Teaching (CLT) and the eclectic approach among teachers in both tertiary and middle levels, this paper discusses possibilities of teaching intonation to EFL-major students at teachers' colleges/universities. It starts by reviewing recent writings about whether or not pronunciation/intonation should be taught in second/foreign language programmes. It then reviews research into the teaching of the pronunciation of English as a second/foreign language to clear the background for a proposal to teach intonation in tertiary institutions where teacher-education is the major concern. Working within Kingdon's theoretical framework, it first explores the theoretical issues involved in teaching intonation; it then suggests practical hands-on ideas for classroom implementation.

选煤是煤炭清洁加工利用的源头技术,干法选煤是干旱缺水地区与易泥化煤炭高效分选提质的重要途径。干法重介质流化床通过上升气流驱动加重质颗粒流化形成一定密度的气固流态化床层,实现对煤炭按密度分选,床层密度均匀稳定性即床层流化质量是决定分选精度的关键。受到气流、气泡、运动内构件、入料等多因素扰动,床层流化行为复杂多变,压力信号呈现出非均匀性、非线性、多尺度特征。基于干法重介质流化床压力信号的轴向差异传递与横向等效扩散特性,着重研究了床层轴向压差波动特征,提出流化质量定量表征方法。结果表明:基于时域分析可知,Geldart A类加重质颗粒床层总压降概率密度分布接近于正态分布;当床层散式膨胀时,由于颗粒间接触力的分布不均,概率密度呈现右偏且尖峰的偏离正态分布。通过频域分析发现,在床层膨胀区间的中末期,气泡主频主导了流化床的整个轴向区间;完全流化后的流化床,气泡主频仅控制着床层中部区域,床层浓度信号主频沿床层轴向分布变化明显。结合时域和频域信号分析结果,提出以轴向床层浓度主频为子区间波动标准差权重值的流化质量表征模型,可以综合评估干法重介质流化床的密度分布均匀性和稳定性,为干法重介质流化床分选密度稳态调控与精准分选提供有力支撑。
