diamagnetic 指物质在磁场中产生微弱排斥力,表现为抗磁性,常用于物理学和材料科学领域。

用法要点

句型搭配

作为形容词时,常用于描述物质属性,如 'is diamagnetic' 或 'has diamagnetic properties';作为名词时,指抗磁性体,如 'a diamagnetic'。

• The material is diamagnetic.
• It exhibits diamagnetic behavior.
• A diamagnetic repels magnetic fields.

介词用法

常与 'in' 连用表示在磁场中,如 'diamagnetic in a magnetic field';也可用 'with' 表示伴随属性,如 'with diamagnetic properties'。

• Diamagnetic in nature.
• With strong diamagnetic effects.
• In a diamagnetic state.

语域说明

主要用于学术和技术语境,如物理学、化学和工程学,日常对话中较少使用,属于专业术语。

• In scientific research.
• For technical applications.
• In academic papers.

基础例句

In our physics class, we learned that copper is diamagnetic and repels magnets slightly.

在物理课上,我们学到铜是抗磁性的,会轻微排斥磁铁。

This material feels different because it has diamagnetic properties that affect magnetic fields.

这种材料感觉不同,因为它具有抗磁性,会影响磁场。

When testing with a magnet, the diamagnetic object moved away instead of attracting.

用磁铁测试时,这个抗磁性物体是移开而不是被吸引。

高级例句

The research paper discusses how diamagnetic materials can be used in magnetic levitation systems for transportation.

这篇研究论文探讨了抗磁性材料如何用于交通领域的磁悬浮系统。

In material science, engineers analyze diamagnetic susceptibility to optimize device performance in electronic applications.

在材料科学中,工程师分析抗磁化率以优化电子应用中的设备性能。

常见错误

❌ 错误:This metal is diamagnetic, so it attracts magnets strongly.
✓ 正确:This metal is diamagnetic, so it repels magnets weakly.

错误在于混淆了抗磁性与顺磁性;抗磁性物质排斥磁场,而非吸引,应使用 'repels' 并注意强度描述为 'weakly'。

❌ 错误:Diamagnetic is a verb that means to resist magnetism.
✓ 正确:Diamagnetic is an adjective or noun describing magnetic repulsion.

错误在于将 diamagnetic 误用为动词;它主要作为形容词或名词,表示抗磁性属性或物体,应避免动词化。

近义词辨析

paramagnetic

paramagnetic 表示顺磁性,物质在磁场中被微弱吸引,而 diamagnetic 表示抗磁性,物质被微弱排斥;两者都涉及弱磁性,但方向相反。

Aluminum is paramagnetic and attracted to magnets, whereas bismuth is diamagnetic and repelled.

non-magnetic

non-magnetic 指无磁性,物质对磁场无反应;diamagnetic 则有弱排斥反应,属于磁性的一种特殊类型,而非完全无磁。

Wood is non-magnetic and unaffected by magnets, but graphite is diamagnetic and shows slight repulsion.
