为了解不同空调风机的内流机制,采用数值分析和PIV实验研究相结合的方法对空调用贯流风机和轴流风机内部复杂的旋涡流动现象进行了研究。结果表明:空调壁挂机用贯流风机内部偏心涡沿轴向具有明显的三维分布特性,偏心涡径向位置沿轴向几乎没有变化,其周向位置沿轴向不断改变。贯流风机偏心涡卷吸区域随负载提高而增强。高负载时,偏心涡更加靠近叶轮中心和蜗壳方向。空调室外机用开式斜流风轮的叶尖涡产生于距叶片前缘1/4区域,靠近吸力面。叶尖涡随风轮转速的提高而增强,并沿着与风轮旋向相反的方向朝下游发展。 相似文献

This article seeks to shed light on the dilemma facing history education in regions beset by a protracted, and as yet unresolved ethno-political conflict. The article will examine this issue by means of a unique test case that observes a dramatic war event in Israeli textbooks. The event in question is the Six-Day War of 1967 and the study of its outcomes. This war stands in the twilight between memory and history and there is an extreme gap between the public history and the formal representation of that war in school textbooks. The question that begs an answer is why such a seminal event in Israeli history is not presented in history textbooks like the country’s other wars. The research methodology, which was conducted on two generations of textbooks, is based upon a comparative discourse analysis. A discussion of the findings contends that a critical pedagogy approach to history education might equip adolescent students with more powerful lenses through which to view several plausible scenarios for healing the wounds of the present by means of a rational and grounded perception of the past. 相似文献

Attention-deficit/hyperactivity disorder (ADHD) and autism are neurodevelopmental disorders that emerge in childhood. There is increasing recognition that ADHD and autism frequently co-occur. Yet, questions remain among clinicians regarding the best ways to evaluate and treat co-occurring autism and ADHD. This review outlines issues relevant to providing evidence-based practice to individuals and families who may be experiencing difficulties associated with co-occurring autism and ADHD. After describing the complexities of the co-occurrence of autism and ADHD, we present practical considerations for best practice assessment and treatment of co-occurring autism and ADHD. Regarding assessment, this includes considerations for interviewing parents/caregivers and youth, using validated parent and teacher rating scales, conducting cognitive assessments, and conducting behavior observations. Regarding treatment, consideration is given to behavioral management, school-based interventions, social skills development, and the use of medications. Throughout, we note the quality of evidence that supports a particular component of assessment or treatment, highlighting when evidence is most relevant to those with co-occurring autism and ADHD across stages of development. In light of the current evidence for assessment and treatment of co-occurring autism and ADHD, we conclude by outlining practical implications for clinical and educational practice. 相似文献
