, 2015 采用图画-词汇干扰实验范式,考察了汉语口语产生过程中词频与音节频率效应、语音促进效应的认知年老化现象及其认知机制。结果发现,老年组的图画命名时间长于青年组,且老年组的词频效应和音节频率效应高于青年组,而语音相关效应低于青年组。老年组中词频和音节频率存在两因素交互作用,青年组则没有,这表明随着年龄增加,老年人的心理词典中不仅语义水平和音韵水平之间的联结强度变弱,而且信息之间的作用模式发生了变化。研究结果为激活不充分假设或传输不足假设提供了证据。

Gaoya dianqi, 2023 “双碳”目标的实施和新型电力系统的建设极大推动了可再生能源并网发电进程，电力系统的结构也因此发生巨大改变。由于可再生电源无法参与电网的惯性和阻尼调节过程，并网后极易造成电网频率失调、负载功率失稳现象。因此，文中提出一种基于虚拟同步机（virtual synchronous generator,VSG）技术的风—光—储系统自适应调频控制策略。首先，在风—光—储VSG系统结构基础上建立数学模型，并分析VSG技术调频特性；然后，综合考虑风电、光伏发电曲线 ...

Wafer‐Scale Amorphous g‐C3N4 With Broadly Tunable Dielectric Properties for 2D Electronics
Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Two‐dimensional (2D) semiconductors are regarded as promising candidates for next‐generation electronics due to their superior electrostatic control; however, their performance is severely constrained by the lack of suitable dielectric materials.

Journal of Animal Ecology, Volume 95, Issue 7, Page 1178-1193, July 2026.This population‐comparative study reveals that male and female parents respond differently to social and ecological conditions. This sex‐specific responsive strategy is related to the incongruent parental care systems across populations in Chinese penduline tits.

International Journal of Applied Linguistics, Volume 36, Issue 2, Page 979-994, May 2026.ABSTRACT Previous research has established the relationships between motivation, anxiety, teachers’ support, and self‐regulated learning (SRL) in English‐as‐a‐foreign‐language (EFL) learning. Most of the studies, however, have taken a variable‐centered approach in addressing the variable correlations, while learners’ characteristics and variable links ...

He jishu上海硬X射线自由电子激光装置X光束传输距离超过1 km，反射镜的角度振动对实验站样品处的光斑影响很大。本文旨在探讨动力吸振器在减小反射镜角度振动的可行性。针对反射镜角度14.6 Hz的环境振动，设计了一个可变刚度的动力吸振器，将其应用于上海硬X射线自由电子激光装置的反射镜调节系统中，以期实现该频率的振动抑制。实验结果表明，通过将动力吸振器的频率调至14.6 Hz，反射镜调节系统14.6 Hz的振动从154 nrad降低至27.9 nrad，其他频率的振动基本无明显变化，整体反射镜角度的振动从193.2 ...

International Journal of Applied Linguistics, Volume 35, Issue 1, Page 274-290, February 2025.Abstract Metacognitive regulation refers to learners’ ability to use a repertoire of metacognitive strategies to guide, observe, and manage thoughts, actions, and emotions in learning activities. It has been widely acknowledged as a significant predictor of language learning success, including writing.

Integrative Conservation, Volume 3, Issue 3, Page 230-243, September 2024.Tropical secondary forest at early sucessional stage had higher diamter growth rate and mortality rate, however, these forests also are more risked to droughts and high temperatures. Rising temperatures and more frequent droughts may decrease the carbon sink capacity of tropical forest ecosystems. Abstract Tropical forests are major carbon sinks on the
