Learner‐Focused Strategy Instruction From the Teachers’ and the Learners’ Perspective
International Journal of Applied Linguistics, EarlyView.ABSTRACT Numerous large‐scale quantitative studies have been conducted to yield a macro‐level picture of the effectiveness of strategy instruction. However, little is understood about learners' actual processing of strategy instruction and interaction with the teachers delivering it.

Research on Grinding and Using Parameters Optimization of Cemented Carbide Cutting Tool [PDF]
, 2015 在航空航天制造领域，航空铝合金零部件是数量最多、制造任务最重的加工对象，其高效加工使用的高端硬质合金刀具多数需要进口。由于我国航空铝合金加工专用硬质合金刀具的研究起步较晚、发展滞后，材料研发、刀具设计以及制造装备技术整体水平不高，尤其缺乏针对不同航空铝合金零件加工用硬质合金刀具从切削机理分析、几何结构设计、磨制技术、加工参数优化整个过程的全链条式研究。本文针对航空铝合金7075加工用硬质合金刀具的磨制机理、刀具铣削性能、刀具几何结构与加工参数优化等方面进行贯通性应用基础研究尝试 ...

Jianzhu Gangjiegou Jinzhan, 2021 为了研究复杂钢管空间节点的应力集中系数,采用有限元软件ANSYS建立了复杂钢管空间节点有限元模型。有限元模型考虑了焊缝的影响,将有限元计算结果与试验结果进行比较,二者吻合较好,从而验证了有限元模型的可靠性。对复杂钢管空间节点模型进行了参数分析,研究了各个参数对节点应力集中系数的影响。参数分析结果表明,主管径厚比γ对节点应力集中系数的影响较大;其他参数对节点应力集中系数的影响较小。对252个参数分析模型的结果进行回归分析,建立了节点各部分应力集中系数的拟合公式。拟合公式计算值与有限元计算值吻合较好 ...

Decoding Paradoxes in Digital Government: Strategies for the Pursuit of Public Value
Public Administration, EarlyView.ABSTRACT This study aims to analyze the complexities of paradoxes in digital government. Through a focused analysis of 34 selected articles, adhering to PRISMA guidelines, it codifies seven paradoxes, categorized into “internal governance paradoxes” and “external engagement paradoxes.” These paradoxes arise from conflicting values among governments ...

Bézier curves with multi-shape-parameters(带多个形状参数的Bézier曲线)
Zhejiang Daxue xuebao. Lixue ban, 2010 基于Bézier曲线升阶的思想,构造了带多个形状参数的Bézier曲线,它具有与Bézier曲线相同的性质.在控制顶点不变的情况下,可通过改变多个形状参数的取值调整曲线的形状.n次Bézier曲线是n次带多个形状参数的Bézier曲线的一个特例,多个形状参数可使曲线变化更灵活.
