It was released on May 12,2017,by the General Administration of Quality Supervision,Inspection and Quarantine of the Peoples Republic of China and the Standardization Administration of the Peoples Republic of China. This paper introduces the necessity of revising the national standard of magnitude,and the main contents,technical points and primary features of the new national standard of magnitude,so that it can be applied better in practice.展开更多

We contest that methods now widely in use at colleges and universities are insufficient to reach modern nationwide targets. We suggest modifications in teaching approach and present ideas for supplementing and enlivening existing materials or replacing them. Much of the article is drawn from our converging experiences both as a Chinese university teacher of English from one aspect and as an English EFL specialist from another. We speak jointly from the ’chalkface’ and wish to share our views and be provoked into seeking solutions to the new challenges for Chinese EFL inherent in targets set by the national standards.展开更多
当前空调系统制冷剂替代工作正在进行中,R290(丙烷)作为碳氢制冷剂,受到行业的广泛关注和追捧,我国也已经将其看作长期替代工质,给予了政策上的倾斜。主要介绍了R290制冷剂在最新的国标中,制冷剂充注量上的变化,通过举例来进一步阐述新...当前空调系统制冷剂替代工作正在进行中,R290(丙烷)作为碳氢制冷剂,受到行业的广泛关注和追捧,我国也已经将其看作长期替代工质,给予了政策上的倾斜。主要介绍了R290制冷剂在最新的国标中,制冷剂充注量上的变化,通过举例来进一步阐述新标准如何计算制冷剂充注量和最小循环风量。然后基于一款1.5 HP R32 APF1变频空调系统,以试验的方式,对比了当该系统的制冷剂从R32切换到R290后,制冷剂充注量和空调系统APF性能变化。最终,结合R290制冷剂的特点,对今后系统的开发提出了目标和展望。展开更多
