成核作用是指物质从液态或气态中形成微小晶核的过程,常见于化学、物理和材料科学领域。

用法要点

句型搭配

通常用作不可数名词,描述过程或现象,常与动词如 'occur'、'promote' 或 'inhibit' 搭配,用于被动语态或作为主语。

• nucleation occurs
• promote nucleation
• inhibit nucleation

介词用法

常与介词 'of' 连用表示成核的对象,如 'nucleation of crystals';在学术语境中,也可用 'in' 表示发生领域,如 'nucleation in polymers'。

• nucleation of ice
• nucleation in solutions

语域说明

主要用于学术、科技或专业语境,如化学、物理、材料科学和气象学,日常对话中较少使用,属于正式术语。

• scientific paper on nucleation
• industrial nucleation process

基础例句

In winter, nucleation of ice crystals often happens on cold windows.

冬天,冰晶的成核作用常发生在冰冷的窗户上。

The scientist explained how nucleation leads to cloud formation.

科学家解释了成核作用如何导致云的形成。

Adding a seed crystal can promote nucleation in the solution.

加入晶种可以促进溶液中的成核作用。

高级例句

The research focuses on heterogeneous nucleation in polymer blends for advanced materials.

这项研究专注于聚合物共混物中的异相成核作用,以开发先进材料。

In metallurgy, controlling nucleation rates is crucial for optimizing alloy properties.

在冶金学中,控制成核速率对于优化合金性能至关重要。

常见错误

❌ 错误:The nucleation is happen quickly.
✓ 正确:Nucleation happens quickly.

错误:误用 'the' 和 'is happen','nucleation' 作为不可数名词通常不加冠词,且 'happen' 应直接作谓语。正确:使用 'Nucleation happens' 更符合英语习惯。

❌ 错误:We need to nucleation the solution.
✓ 正确:We need to promote nucleation in the solution.

错误:将 'nucleation' 误用作动词。正确:'nucleation' 是名词,应搭配动词如 'promote' 或 'initiate' 来表达动作。

近义词辨析

crystallization

'crystallization' 指整个从液态形成晶体的过程,包括成核和生长阶段;而 'nucleation' 特指初始形成微小晶核的阶段,是结晶的第一步。

Nucleation is the first step in the crystallization of sugar from a supersaturated solution.

precipitation

'precipitation' 在化学中常指从溶液中析出固体,可能涉及成核,但更广义,包括沉淀现象;'nucleation' 更专注于核的形成机制。

Precipitation of salts can occur through rapid nucleation under certain conditions.
