轧机提速对四列圆柱滚子轴承的影响和优化措施研究

国内某钢厂轧机进行了提速,导致支承辊上四列圆柱滚子轴承出现温升过高情况。针对此问题,对该轴承提速前后的摩擦力矩和发热量进行了计算比较,显示速度对摩擦力矩的影响不明显,与发热量近似成正比例关系。对轴承进行了降低温升优化。采取的主要措施为减少相互滑动部位接触面积,增设散热油路;降低接触面粗糙度;优化轴承油孔改善散热效果。提出了滚子端面和挡边点接触的简化计算方法。优化后的轴承经应用后温升明显减缓,提高了使用寿命。     

科学发展观与“四大文明”建设

科学发展观就是“以人为本”的新的可持续发展观,它要求树立以人为中心的理念,坚持全面发展,协调 发展,可持续发展。科学发展观的这些要求,体现在全面建设小康社会的进程中,就是要着力建设好物质文明、精神 文明、政治文明和生态文明“四大文明”。通过“四大文明”建设,实现全面建设小康社会的战略目标。     

试论元散曲中的"四季歌"

元散曲中"四季歌"的题材内容、表现形式及与戏曲艺术构思方式上的相似性,显示了同一历史阶段中不同艺术形式相互影响、相互渗透的规律性现象.     

"四大名旦"和20世纪前期的上海

京剧"四大名旦"--梅兰芳、程砚秋、荀慧生、尚小云先后成名上海,从而促成了京剧鼎盛的局面,这是中国戏曲史上一个特别值得注意的现象.他们成名沪上缘于上海是个名角相对较少,束缚较少而宣传发达的新兴都市.四大名旦的上海之行带给他们的不仅是声名的鹊起,也使他们的演艺突飞猛进;而他们的"走穴"申城也对上海京剧舞台产生了深刻影响.

Families’ perceptions of early childhood educators’ fostering conversations and connections by sharing children's learning through pedagogical documentation

ABSTRACT

Belonging, Being and Becoming: The Early Years Learning Framework for Australia emphasises that families have an important role in their children's learning and it recognises that their earliest development is influenced through these relationships and adds that partnerships can be fostered with families by early childhood educators sharing the children's documented experiences. The research discussed employed an in-depth structured questionnaire. It involved 37 families with children aged from three to five years who attended an early learning centre in Northern Tasmania, Australia. The aim of this research was to determine these families’ perceptions, beliefs and experiences of educators sharing children's learning through pedagogical documentation. The documentation included hard copy and digital formats of the children's learning, capturing their voices and explorations. The findings show that families consider the sharing of documentation fosters family conversations about the children's learning experiences and helps to create stronger connections between the centre, home and extended family. Another recurring theme from the families’ responses was that children gain pride and a positive sense of identity when their documented work is shared with families.
