The number of foreign students studying in Wenzhou, China has increased dramatically as a result of the Belt and Road Initiative. Learning the motivations and leisure constraints of foreign students' participation in local cultural and folk activities in Wenzhou is beneficial to promoting cultural adaptation, strengthening Chinese cultural self-confidence, and improving Wenzhou's international image. Based on the hierarchical model of leisure constraints (personal constraints, interpersonal constraints, and structural constraints), this study has tended to focus on the leisure constraints for foreign students participating in local folk and cultural activities in Wenzhou. A total of seven participants were included in the analysis.

纵观高考建制70年的政策演变,其大致历经了统招方向的确定、遭遇否定并中断、恢复与科学化探索以及建立新高考体系四个发展阶段。由于高考制度内外部关系的复杂性,高考改革主要遵循三大逻辑,即:以满足“多维需求”为导向的适应性改革逻辑、以注重“积小变大”为策略的渐进式改革逻辑和以坚持“实事求是”为原则的稳中求变改革逻辑。从高考政策的演变特征来看,演变动力实现了由政治主导到多元利益博弈的转变,演变取向完成了由追求效率与科学到强调公平与质量的转向,演变路径基本以由试点试验到全面铺开为主。基于我国新时代深化教育评价改革的目标,未来的高考政策将呈现四大发展趋势:一是综合评价招生将成为高校招生主渠道;二是高考指挥棒将转向引导学生素质全面发展;三是高考制度体系将趋于相对成熟与稳定;四是高考改革将注重构建高质量人才选拔体系。

非共沸制冷剂在相变过程中存在温度滑移,能够缩小相变过程的传热温差,进而减小换热器的传热不可逆损失,有利于提高制冷循环的效率,非常适合于变温热源的应用。所以非共沸制冷剂在变工况的工业制冷中有较大的应用前景。对于非共沸制冷剂,换热器选型时应注意温度滑移造成的影响,否则可能无法保证正常的换热器余量。对于冷凝器应选择泡点作为计算冷凝温度;蒸发器选型应使用露点温度。
