đẳng trọng
Definition
- Noun (Geography, Geology, Physics):
- Isogam: A line on a map connecting points of equal gravitational acceleration or equal values of gravity anomaly.
- Isogam (specific to magnetism): A line connecting points of equal magnetic force or equal vertical magnetic intensity. (Note: This usage is less common and context-specific.)
Usage Examples
- Noun:
- Bản đồ này vẽ các đường đẳng trọng để nghiên cứu trường trọng lực. (This map draws isogams to study the gravity field.)
- Sự phân bố các đường đẳng trọng cho thấy cấu trúc địa chất bên dưới. (The distribution of isogams reveals the underlying geological structure.)
Advanced Usage
- "Đường đẳng trọng": This is the most common full term, meaning "isogam line" or simply "isogam."
- Các đường đẳng trọng trên biểu đồ rất sát nhau, chỉ ra gradient trọng lực lớn. (The isogams on the chart are very close together, indicating a large gravity gradient.)
Variants and Related Words
- Đẳng từ (n): Isomagnetic line; a line connecting points of equal magnetic force.
- Đường đồng mức (n): Contour line (a more general term for any line connecting points of equal value, such as elevation or pressure).
Synonyms
- Isogam: The direct technical synonym.
- Isogam line: A more explicit term.
- Line of equal gravity: A descriptive synonym.
Notes on Usage
- Technical Term: "Đẳng trọng" is a specialized scientific term used primarily in geophysics, geology, and geodesy. It is not used in everyday conversation.
- Clarification: In modern technical English, "isogam" is the standard equivalent. The related French term "isogamme" confirms this technical lineage.
