ABSTRACT This paper examines the features of metadiscourse across different teacher moves in university linguistics classroom discourse and the teaching strategies reflected in its use. The results reveal that teachers employ diverse metadiscourse during classroom interactions to support student reasoning.

在已有研究的基础上,进一步探究分层型梯形加劲肋对内嵌组合平钢板剪力墙滞回性能的影响。设计出分2层和3层的交叉密肋内嵌组合平钢板剪力墙,均为双层单跨试件。利用有限元软件ABAQUS对其进行非线性和线性荷载作用加载,与已有的不分层交叉密肋平钢板组合剪力墙进行对比分析。研究结果表明:结构的承载力随着梯形加劲肋分层数目的增加而逐渐降低,但是其延性却随之增加,对比分析3个试件有限元模拟的结果,结构的承载能力和延性性能并非随着梯形加劲肋分层数目的增多而呈现线性变化 ...

ABSTRACT Objective Placental dysfunction can result in small‐for‐gestational age (SGA) or fetal growth restriction (FGR). The aim of this prospective cohort study was to assess the association of the cerebroplacental ratio (CPR) and other more conventional fetoplacental Doppler indices, circulating placental growth factor (PlGF) levels and soluble fms ...

为研究低屈服点钢材LY100在反复拉力作用下的力学性能,设计LY100钢与Q345钢或Q235钢焊接连接的材性试件,共进行4组18个材性试件的单调和反复受拉加载试验研究。获得6种不同加载制度下试件的荷载-位移曲线、应力-应变曲线、滞回性能、超低周疲劳破坏机理以及延性特征等。研究结果表明,焊接接头对试件的超低周疲劳性能有不利影响,焊接接头使LY100钢材力学性能的稳定性和延性变差;LY100钢与Q345钢或Q235钢焊接后,材性试件的强度提高但延性下降;反复拉力作用下,带有焊接接头的材性试件呈现强度硬化 ...

The Spiritual Path of Transformation1
Abstract Transformation is an essential component of individuation; it is not a linear but a circular process, encompassing experiences of standstill and deadlock where no longitudinal continuation is visible. Jung describes transformation in alchemical terms as a shared dialectical “reaction” between patient and analyst.

钢板仓组合剪力墙是一种新型抗侧力构件,是以两块钢板和圆管支撑组成基本单元,空腔内填充混凝土的组合剪力墙。基于ABAQUS软件,建立了考虑材料非线性和几何非线性等因素影响的钢板仓组合剪力墙有限元分析模型,分析了钢板仓组合剪力墙圆管支撑布置密度、轴压比、含钢率及高宽比对其水平承载力和延性性能的影响。分析结果表明,钢板仓组合剪力墙具有较高的水平承载力和良好的变形能力,圆管支撑的布置密度对其延性性能和变形能力影响较大。支撑布置方式选用无支撑、1列(1×5)、2列(2×5)、3列(3×5)四种方式 ...
