“马鞍点”通常指数学或物理学中的概念,指在某一方向上为极大值,另一方向上为极小值的临界点,其形状类似马鞍。不过,关于“马鞍”的释义仅涉及实物(如、),即放置在马背上供人骑坐的器具,两端高中间低。若需更专业的“马鞍点”定义(如优化问题中的鞍点),当前搜索结果未提供直接关联信息,建议结合具体学科领域进一步查询。
共沸物(Azeotrope)是指两种或多种液体以特定比例混合后,形成具有固定沸点的混合物,其气相与液相组成相同,无法通过常规蒸馏分离。主要特点包括:
常见共沸物包括乙醇-水(沸点78.13℃)、盐酸-水(沸点110℃)等。
马鞍点共沸物(mǎ sān diǎn gòng fèi wù)是一个比较专业的词汇,主要指混合物中最后一滴液体沸腾的温度,也就是可以同时蒸发两种或两种以上组成混合物的纯组分。
The term for 马鞍点共沸物 in English is azeotrope, which refers to a mixture of two or more liquids that boils at a constant temperature and composition, meaning the vapor has the same ratio of components as the original mixture.
The pronunciation of azeotrope is ey-zee-uh-trohp.
Azeotropes are often used in chemical processes, especially in distillation, where they can be used to separate a mixture of liquids that would be difficult or impossible to separate by normal distillation. They are also used in refrigeration systems.
Example: The azeotrope of ethanol and water has a boiling point of 78.2 °C at atmospheric pressure.
翻译:水和乙醇的马鞍点共沸物在标准大气压下的沸点是 78.2 ℃。
Synonyms: constant boiling mixture, constant boiling point mixture。
翻译:常沸混合物。
Antonyms: non-azeotropic mixture。
翻译:非共沸混合物。
Azeotrope is a relatively technical term and is mainly used in scientific and chemical fields, so it is not commonly used in everyday life.
翻译:azeotrope 是一个相对专业的术语,主要用于科学和化学领域,因此不能在日常生活中常见到。
