阳性

• 拼音: yáng xìng
• 汉字拆解: 阳 = 阝(earthwork/mound) + 昜 (rising sun — the bright, sunny side of a hill); 性 = 忄(heart/mind) + 生 (life — the innate disposition of a living being)

含义

Positive (in a test result); yang polarity; masculine gender (in grammar). In medicine, indicates a test has detected the target substance or condition.

In medical contexts, 阳性 means a positive test result (e.g., 核酸检测阳性 — nucleic acid test positive). In traditional Chinese philosophy, 阳 is the active, bright, masculine principle of yin-yang dualism. In linguistics, refers to the masculine gender in languages that have grammatical gender. The opposite is 阴性 (negative result / yin / feminine).

例句

2. 传统中医理论认为，人体的阴阳平衡至关重要，阳性体质的人往往表现为体温偏高、面色红润、精力充沛，但也容易出现上火的症状。
3. 在学习法语或西班牙语时，中国学生往往对名词的阴阳性分类感到困惑，因为汉语本身并没有语法性别这一概念。

• 中医所说的阳性体质并不是一种疾病诊断，而是对个体先天禀赋和后天调养所形成的生理特征的一种整体描述和分类参考。(What traditional Chinese medicine calls a yang constitution is not a disease diagnosis but rather a holistic description and classificatory reference for the physiological characteristics formed by an individual's innate endowment and acquired lifestyle habits.)
