手性是指物体或分子与其镜像不能完全重合的性质,常见于化学和物理学中描述不对称结构。

用法要点

句型搭配

常用于描述分子或物体的不对称性,常与介词'of'连用表示所属关系,或与'in'连用表示在某个领域中的手性。

• the chirality of a molecule
• chirality in organic chemistry
• determine the chirality

介词用法

主要与'of'搭配表示手性的所属对象,如分子的手性;与'in'搭配表示手性存在的领域,如化学中的手性。

• chirality of the compound
• chirality in nature
• chirality of light

语域说明

这是一个高度专业化的术语,主要用于学术和科学语境,如化学、物理学、生物学和材料科学,日常对话中极少使用。

• chirality in pharmaceuticals
• chirality in physics
• chirality in biology

基础例句

In our science class, we learned about the chirality of molecules and how it affects drug effectiveness.

在科学课上,我们学习了分子的手性以及它如何影响药物的有效性。

The teacher explained that chirality is why some molecules have mirror images that don't match.

老师解释说,手性是一些分子与其镜像不匹配的原因。

When discussing natural compounds, chirality often comes up as a key factor in their properties.

在讨论天然化合物时,手性常常作为其性质的关键因素被提及。

I read an article about chirality in everyday objects, like how our hands are chiral.

我读了一篇关于日常物体中手性的文章,比如我们的手是如何具有手性的。

高级例句

The chirality of pharmaceutical compounds is critical for ensuring drug safety and efficacy in clinical trials.

药物化合物的手性对于确保临床试验中的药物安全性和有效性至关重要。

In advanced materials science, researchers study chirality to develop new chiral nanomaterials with unique optical properties.

在先进材料科学中,研究人员研究手性以开发具有独特光学性质的新型手性纳米材料。

The conference paper discussed how chirality in asymmetric catalysis can enhance reaction selectivity in industrial processes.

会议论文讨论了不对称催化中的手性如何提高工业过程中的反应选择性。

常见错误

❌ 错误:The chirality for this molecule is important.
✓ 正确:The chirality of this molecule is important.

错误使用了介词'for',正确应用'of'来表示手性所属的对象,如分子。

❌ 错误:Chirality means the same as symmetry.
✓ 正确:Chirality is related to asymmetry, not symmetry.

手性描述的是不对称性,与对称性相反,常见混淆需注意区分概念。

近义词辨析

asymmetry

不对称性是一个更广泛的术语,指缺乏对称性;而手性特指物体或分子与其镜像不能重合的一种不对称性,常用于科学领域。

Asymmetry can refer to any lack of balance, but chirality specifically describes non-superimposable mirror images in molecules.

handedness

手性通常用于描述分子或物体的镜像不对称性;而handedness更常用于日常语境,如描述左撇子或右撇子,但在某些科学语境中可互换使用。

In physics, chirality of particles is similar to handedness, but chirality is more precise in chemical contexts.
