modelling n. 模型制造;塑造术 模型制造;塑造术 modelling n 1: a preliminary sculpture in wax or clay from which a finished work can be copied [ synonym: { modeling}, { modelling}, { molding}, { moulding}] 2: the act of representing something ( usually on a smaller scale) [ synonym: { model}, { modelling}, { modeling}] Modeling \ Mod" el* ing\, n. ( Fine Arts) The act or art of making a model from which a work of art is to be executed; the formation of a work of art from some plastic material. Also, in painting, drawing, etc., the expression or indication of solid form. [ Written also { modelling}.] [ 1913 Webster] { Modeling plane}, a small plane for planing rounded objects. { Modeling wax}, beeswax melted with a little Venice turpentine, or other resinous material, and tinted with coloring matter, usually red, -- used in modeling. [ 1913 Webster]
Model \ Mod" el\, v. t. [ imp. & p. p. { Modeled} or { Modelled}; p. pr. & vb. n. { Modeling} or { Modelling}.] [ Cf. F. modeler, It. modellare.] To plan or form after a pattern; to form in model; to form a model or pattern for; to shape; to mold; to fashion; as, to model a house or a government; to model an edifice according to the plan delineated.

本综述概述了用于带有阴离子交换膜 (AEM) 的水电解槽(也称为零间隙碱性水电解槽)的催化剂、膜和膜电极组件 (MEA) 的新兴概念。 最近的进展很大程度上归功于材料化学、MEA 设计和优化操作条件的改进。 阴离子交换聚合物(AEP)的研究主要集中在阳离子头 主链 侧链结构以及离子电导率和碱性稳定性等关键性能上。 人们提出了几种方法,例如交联、微相和有机 无机复合材料来提高AEM的阴离子交换性能以及化学和机械稳定性。 目前,许多 AEM 的值都超过了 0 1 S cm(在 60–80 °C 时),但在超过 60 °C 的温度下的稳定性还需要进一步增强。 析氧反应(OER)仍然是一个限制因素。 对薄层 OER 数据的分析表明 NiFe 型催化剂具有最高的活性。
