摘要：The Irtysh River Basin refers to a water conservation area and a vital ecological barrier in Xinjiang and also partially in Central ***,the technical solution for the ecological protection and the restoration of the Mountains-Rivers-Forests-Farmlands-Lakes-Grasslands system(MRFFLGs)pilot project in the Irtysh River Basin is refined,by complying with the core concept,i.e.,"mountains,rivers,forests,farmlands,lakes and grasslands are a community of life".The solution stresses the specific characteristics of ecologically protecting and restoring MRFFLGs in the Irtysh River Basin,which aim to reduce ecological water use,soil erosion,forest and grassland degradation,the ecological destruction of mines,water environment pollution and other *** overall protection,system restoration,district policy,and problem orientation as the overarching ideas,162 sub-items of 44 major items with seven categories have been designed and implemented in the *** addition,some highlights of the management experience that are worth promoting when the pilot project is being implemented are also summarized(e.g.,the use of laws to solve historical problems,scientific argumentation and third-party evaluation,proactive guidance for the engagement of people,modern information technology support,and integration with local sustainable development).Lastly,four policy suggestions are proposed:(1)Building a model of systematic protection and restoration by using basins as the basic geographic unit;(2)Establishing and optimizing key weak links of systems and mechanisms;(3)Focusing on remedying the shortcomings of regional talents,technology and capital;and(4)Promoting the MRFFLGs project to integrate"industry,city,people,and tourism"for carrying out a large-scale system project.

摘要：话语制度分析使用动态的方式研究制度变迁,它关注观念的实质内容与话语的交互过程,为政策分析提供了新的制度视野、解释功能和方法论意蕴。我国当代美育政策演进话语制度分析模型由观念分析、话语分析、制度分析三者相互渗透、融合而构成。我国当代的美育观念在冲突和博弈中经历了由“粗浅”到“精细”的演变;美育的主流性话语性互动既有自下而上的,也有社会大众层面的;美育政策的制定者需要综合考量思想性、艺术性、实践性和综合性,致力于社会现实与美育价值的统一。

摘要：基于对220 t/h循环流化床锅炉内风帽的改进设计,搭建了风帽冷态水模型实验台,分别对此种新型风帽进行了阻力特性实验、均匀性实验、临界流化实验。实验结果表明:此种新型风帽安装之后,流化状态明显改善,阻力系数明显减小,从而证实了本风帽结构的合理性,为循环流化床锅炉风帽的优化研究提供了理论依据,为风帽设计开发提供了新的思路。
