Gongye shui chuli, 2011 采用光电催化氧化法降解季铵盐类杀菌剂十二烷基二甲基苄基氯化铵（1227）废水。以紫外灯为光源，DSA 电极为阳极，石墨电极为阴极，考察了阳极材料、光催化剂投加量、外加电场强度、极板间距、初始pH 对COD 去除率的影响。结果表明：光电催化氧化过程的最佳外加偏压为20 V，光催化剂最佳投加质量浓度为0.3 g/L，极板间距为0.5 cm，pH 为8.27，反应3 h 后1227 废水的COD 去除率可达到87%，TOC 去除率达到92%。光电催化氧化法的降解率高于单纯的光催化氧化和电催化氧化降解率之和 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT With the increasing number of Chinese international students in Australian universities, intercultural competence has become a critical factor influencing their interactions with Australian tutors in university classroom settings. Existing research often examines students’ intercultural competence from a single‐method or single‐perspective ...

Gongye shui chuli, 2000 电化学方法处理含有机污染物的污水已引起广泛的兴趣。在电催化电极的作用下,电化学反应和化学催化作用结合,导致有机分子的电催化降解。由于粒子群电极可以提高电解效率,所以近年来受到相当的关注。选用合适的电极材料和采用粒子群电极可以加速电化学反应速率和增进电化学对催化作用的促进作用,因而在有机污水处理中它们将有助于有机物的电化学转化反应。其中论述了两个重要的问题:电极材料选择的科学依据和粒子群电极的应用前景。

四川大学学报. 自然科学版, 2008 基于紧束缚的Su-Schrieffer-Heeger(SSH)模型,利用非绝热的动力学方法,研究了基态非简并聚合物中负电极化子(电子型极化子)和正电极化子(空穴型极化子)的碰撞过程.研究发现,弱电场下两个极化子碰撞分开再相遇形成极化子激子,中等强度电场下它们碰撞分开后成为两个准粒子,强电场下负电极化子和正电极化子碰撞后直接解离.

International Journal of Applied Linguistics, EarlyView.ABSTRACT Many existing rubrics for L2 argumentative writing prioritize form‐based linguistic accuracy and complexity while insufficiently addressing substantive argumentative rigor and effectiveness. This limitation is further complicated by cross‐cultural variation in rhetorical conventions and educational practices, which challenge the direct ...

Off‐Task Talk to Manage Relationship Work During Student Group Work in Second Language Classrooms
International Journal of Applied Linguistics, EarlyView.ABSTRACT This paper presents a conversation analytic study on student relationship work in off‐task talk (OTT) during group work in foreign language classrooms. Often seen as disengagement from tasks, OTT's social and relational functions in student classroom group interaction and formation remain underexplored.

Gaoya dianqi, 2017 回复电压测量方法（return voltage measurement,RVM）能有效检测变压器固体绝缘的含水量,然而对于含有局部峰值点的回复电压极化谱难以给出明确的诊断结论。文中在扩展Debye模型基础上,仿真分析了模型参数变化对极化谱和主时间常数CTC、回复电压峰值最大值Urmax的影响规律,并提出将扩展Debye模型不同时间常数支路数作为新的特征量,最后验证了该特征量的可行性。仿真和试验结果表明:RVM极化谱前、中、尾3部分分别对应着油纸绝缘变压器油中偶极子转向极化 ...

World Food Policy, Volume 12, Issue 2, November 2026.ABSTRACT This study explores environmental justice issues in coastal food systems, focusing on conflicts between small‐scale fisheries and the energy sector due to differing goals in managing food and energy sources. It does so by examining the interdependence between institutions, policies, and different types of knowledge; key elements in building ...

Partisanship, Deservingness, and the Attitudinal Policy Feedback Process for Social Policy
Policy Studies Journal, Volume 54, Issue 4, November 2026.ABSTRACT In an era of identity‐based partisan polarization, we examine whether social policies can still generate positive attitudinal feedback among beneficiaries. Drawing on nationally representative survey data, we demonstrate that partisanship conditions the policy feedback process through divergent perceptions of group deservingness.
