电化学去除污水中磷的工艺研究

open access: yesGongye shui chuli, 2021
采用正交试验法研究不同电极、电压、电流对电化学去除污水中磷的影响。结果表明:磷的去除率随电压的增加而增大,电流的影响不显著。对于磷质量浓度为0.500 mg/L的中水,最佳电解条件为:铁作正极、铝作负极,电压25 V,电流0.5 A,电解时间40 min,磷去除率为96.0%。电解磷质量浓度为12.97 mg/L的废水,最佳电解条件为:铁作正极、铝作负极,电压30 V,电流1 A,电解时间为60 min,磷去除率为96.77%以上。处理后水中磷的浓度可达到国家排放标准和回用要求。

某些弱拟正规子群对有限群可解性的影响

open access: yes四川大学学报. 自然科学版, 2007
利用弱拟正规子群及S-弱拟正规子群,得到了有限群的可解性的一些新刻画.主要获得了下列结论:(i)若群G有两个不共轭的可解极大子群均在G中弱拟正规,则G可解;(ii)群G可解当且仅当G存在可解的极大子群在G中弱拟正规,且G与交错群A5、PSL2(7)及PSL3(3)无关.

A methodological assessment and reflection on member checking as a form of participant validation for conservation social science

open access: yesConservation Biology, EarlyView.
Abstract Qualitative approaches are increasingly applied in conservation social science, yet methodological reflection remains limited. Member checking, a process of returning findings to participants for feedback, is widely recognized outside conservation as a means to enhance rigor and reciprocity, but it is rarely reported in conservation research ...

Intact coastal nursery rearing amid climate‐driven phenological shifts in threatened salmon

open access: yesConservation Biology, EarlyView.
Abstract Literature linking phenology to climate has proliferated in recent decades and shows that climate change has reorganized seasonal opportunities worldwide. However, this literature often quantifies changes in point measures of timing (e.g., beginnings and peaks) without context about duration (e.g., rearing season length) or performance (e.g ...

How endorser attributes influence conservation communication

open access: yesConservation Biology, EarlyView.
Abstract Conservation communication often uses the celebrity endorsement strategy. However, robust evidence regarding its effectiveness is still limited. More importantly, practitioners do not have guidelines for selecting an ideal endorser because there is no clear consensus on what endorser attributes are most critical.

Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.

The Development and Validation of the Chinese Vocabulary Levels Test

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT In response to the increasing need for effective Chinese vocabulary assessments, this study developed the Chinese Vocabulary Levels Test (CVLT), a test designed for intermediate‐level Chinese as a second or foreign language (CSL/FL) learners, based on the vocabulary lists (levels 4–6) from the Chinese Proficiency Grading Standards for ...

The Impact of AI‐Assisted L2 Learning on Learners’ Emotions: A Meta‐Analysis

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT The scope of research on AI‐assisted second/foreign language (L2/FL) learning has expanded beyond learning outcomes to focus on learners’ emotional experiences. Despite their proliferation, existing empirical findings are inconsistent, and few studies have systematically synthesized the impacts of AI‐assisted L2 learning on learners’ emotional
