"gained"是动词gain的过去式和过去分词形式，具有多重含义与使用场景。根据《牛津英语词典》的定义，其核心词义为通过努力或自然过程获取某物，既可指具体实物的增加，也可用于抽象概念的积累。该词在《剑桥词典》中被归类为英语学习B2级重点词汇，常见于学术写作和日常交流。
具体释义可细分为：
经济价值增长：指利润、财富或价值的增加。例如："The company gained 20% market share after product innovation"（产品创新后公司市场份额增长20%），此用法常见于《经济学人》商业版块报道。
物理量增加：描述速度、重量等可量化指标的提升。美国物理学会期刊曾用"the spacecraft gained velocity during gravitational assist"（航天器借助引力弹弓效应提速）解释天体力学原理。
能力/素质提升：表示技能、经验或特质的积累。哈佛大学职业发展研究中心在2023年度报告中指出："Employees gained cross-cultural communication skills through global projects"（员工通过全球项目获得跨文化沟通能力）。
该词的近义词辨析需注意：acquire侧重长期积累（如知识），obtain强调主动获取（如许可），attain多指达成目标，而gain更侧重实际获得的增量。《朗文当代英语词典》特别标注其反义词为"lose"，二者构成典型反义关系。
“Gained”是动词“gain”的过去式和过去分词形式，含义主要包括以下几个方面：
获得/赢得（通过努力或竞争）
例：She gained a scholarship through hard work.（她通过努力获得了奖学金）
增加/增长（常用于物理量或抽象概念）
例：The car gained speed on the highway.（汽车在高速公路上加速了）
受益/优势
例：The team gained an advantage by changing tactics.（球队通过改变战术获得优势）
逐渐达到（如到达某个地点或状态）
例：They finally gained the mountaintop after hours of climbing.（攀登数小时后，他们终于到达山顶）
常见搭配：
反义词：lose（失去）、decline（减少）
