The effects of morphological structure on reading proficiency—A developmental study

The present report with three inter-related studies examined the effects of morphological complexity on reading proficiency in 103 fourth graders, 88 fifth graders and 107 sixth graders trichotomized into below average, average and above average readers. The reaction time paradigm and the developmental framework with three age groups provided more sensitive and stable results for inferring mental processes in accessing the lexicon. Study 1 on lexical decision with visually presented words and non-words with different morphemic boundaries suggests that words can be accessed in a decomposed state as morphemes by children. Study 2 and the complementary Study 3 requiring the vocalization of derived or base forms of words primed by target items in sentence frames indicate that words might be accessed in full forms. Further, the depth of derivational morphology and of base morphology with correlated phonological changes affect reading proficiency.     

行星际磁云及其相关事件的综合研究

根据SOHO飞船上的LASCO和EIT探测器和GOES卫星的关于太阳活动的观测资料以及ACE和Wind飞船在地球轨道附近关于太阳风等离子体和行星际磁场的观测数据,分析了日冕物质抛射(CME)、行星际磁云和地磁暴的相关性.包括具有地磁效应的晕状CME的日面源区位置分布,日冕物质抛射的中等周期分析,产生地磁暴的行星际参数的阈值等等.作为行星际复杂抛射的一种,首次提出了多重磁云的概念.通过分析观测事例,总结出了多重磁云的一些观测特征,并认为其具有潜在的强大的地磁效应.此外,利用观测资料,研究了激波进入磁云并引起地磁暴的现象.通过建立简单的理论模型,初步分析了激波在穿越磁云的过程中,所能引起的地磁暴的强度的变化.     

Thermal mixing of two miscible fluids in a T-shaped microchannel

In this paper, thermal mixing characteristics of two miscible fluids in a T-shaped microchannel are investigated theoretically, experimentally, and numerically. Thermal mixing processes in a T-shaped microchannel are divided into two zones, consisting of a T-junction and a mixing channel. An analytical two-dimensional model was first built to describe the heat transfer processes in the mixing channel. In the experiments, de-ionized water was employed as the working fluid. Laser induced fluorescence method was used to measure the fluid temperature field in the microchannel. Different combinations of flow rate ratios were studied to investigate the thermal mixing characteristics in the microchannel. At the T-junction, thermal diffusion is found to be dominant in this area due to the striation in the temperature contours. In the mixing channel, heat transfer processes are found to be controlled by thermal diffusion and convection. Measured temperature profiles at the T-junction and mixing channel are compared with analytical model and numerical simulation, respectively.     

乡村学校课程建设的空间悖论及其消解

学校课程建设是在物理与社会空间中开展的课程资源特色化开发、序列化建构的教育实践.在乡村振兴和城镇化发展的时代背景下,乡村学校的课程建设蕴含着特定的空间权利及空间哲学问题.现实的乡村学校是嵌入乡村的,拥有特色化的课程发展空间,但在价值定位上却是逃离乡村的,在课程建设中漠视甚至吞噬着乡村取向的课程发展空间,由此形成乡村学校课程建设的空间悖论.为消除上述悖论,乡村学校需要立足本土知识与儿童经验,建设乡村学校优质课程;同时要整合地方经验与开放空间,拓展乡村学校课程视域,还要加强课程知识转化与价值建构,改善乡村儿童的自我理解.
