khác cực
Definition
- Adjective:
- Heteropolar: In physics and electricity, describes a molecule, crystal, or system that has two distinct, opposite poles (such as positive and negative). It is the opposite of homopolar.
Usage Examples
- Adjective:
- Phân tử nước là một phân tử khác cực. (The water molecule is a heteropolar molecule.)
- Liên kết ion tạo nên các tinh thể khác cực. (Ionic bonds form heteropolar crystals.)
Advanced Usage
- This term is highly specialized and is primarily used in scientific contexts, especially in physics, chemistry, and electrical engineering.
- It describes the fundamental property of having separated positive and negative charge centers, which is crucial for understanding molecular polarity, dielectric materials, and certain electrical phenomena.
Variants and Related Words
- Cực (n): Pole (e.g., positive pole, negative pole).
- Lưỡng cực (n): Dipole (a pair of equal and opposite electric charges or magnetic poles separated by a small distance).
- Phân cực (v/n): To polarize / polarization.
- Đồng cực (adj): Homopolar (having uniform polarity or no separate poles).
Synonyms
- Có hai cực: Having two poles.
- Phân cực: Polarized (though this often describes the state or result, while "khác cực" describes the inherent property).
Notes
- "Khác cực" is a compound adjective formed from "khác" (different) and "cực" (pole). It is a direct translation of the international scientific term "heteropolar."
- It is not commonly used in everyday language and has no idiomatic expressions or phrasal verbs associated with it in general usage. Its application is strictly technical.
