Since the new curriculum reform,labor education has gradually shed its marginalized position in the“five educations,”and the labor curriculum has become an independent course officially separated from comprehensive practical activity *** the practical path of labor curriculum in compulsory education in China has become the primary task of labor education in *** on the practical situation of labor curriculum in compulsory education in China,drawing on the theory of overlapping influence domains,and from the perspective of collaborative education among family,school,and community,this paper proposes a curriculum practical path of“school-led”family-school-community collaboration and a curriculum practical path guided by“student-centered”sentiment,in order to provide references for the practice of labor curriculum in compulsory education in China.

舆论是一种信息传播活动,是公众关于现实社会以及社会中的各种现象、问题所表达的信念、态度、意见和情绪表现的总和。舆论作为现实世界的反映途径之一,对社会影响巨大。现代广告活动不断衍生出新的舆论现象,广告传播的广泛性、强制性、隐蔽性等特征为舆论的形成提供了便利。广告与舆论联系紧密,然而这种互动关系的研究却没有得到广泛的重视,学术观点零散地分布于各个学科的研究当中。本文通过梳理中外学者观点,将广告与舆论的互动关系总结为四个方面:广告代表舆论,广告引导舆论,广告控制舆论,舆论反映广告效果。在系统分析下意图为后续研究打下基础。

Tungsten(W)accumulation in the core,depending on W generation and transport in the edge region,is a severe issue in fusion *** to standard divertors(SDs),snowflake divertors(SFDs)can effectively suppress the heat flux,while the impact of magnetic configurations on W core accumulation remains *** this study,the kinetic code DIVIMP combined with the SOLPS-ITER code is applied to investigate the effects of divertor magnetic configurations(SD versus SFD)on W accumulation during neon injection in *** is found that the W concentration in the core of the SFD is significantly higher than that of the SD with similar total W erosion *** reasons for this are:(1)W impurities in the core of the SFD mainly originate from the inner divertor,which has a short leg,and the source is close to the divertor entrance and upstream ***,the W ionization source(S_(W0))is much stronger,especially near the divertor entrance.(2)The region overlap of S_(W0)and F_(W,TOT)pointing upstream promote W accumulation in the ***,the influence of W source locations at the inner target on W transport in the SFD is *** impurity in the core is mainly contributed by target erosion in the common flux region(CFR)away from the strike *** is attributed to the fact that the W source at this location enhances the ionization source above the W ion stagnation point,which sequentially increases W ***,the suppression of far SOL inner target erosion can effectively prevent W impurities from accumulating in the core.
