bifilar

Thân thiện

A scientist adjusts the bifilar suspension of a delicate instrument.

Definition

Adjective 1. Having or using two filaments or threads: Describes something that incorporates or operates with two fine strands, wires, or fibers, often arranged in parallel. In scientific and technical contexts, it often refers to a specific winding or suspension method using two parallel threads to increase stability or precision.

Usage

The adjective "bifilar" is highly specialized and is used almost exclusively in technical fields such as physics, engineering, and instrument design. It modifies nouns to describe their two-threaded construction or mechanism. - It is typically used attributively (before a noun), e.g., bifilar winding, bifilar suspension. - It is not commonly used in everyday conversation.

Examples

• The galvanometer's needle was held in place by a bifilar suspension to minimize friction.
• A bifilar winding on the inductor helped to cancel out unwanted magnetic fields.
• The precise measurement was made possible by the instrument's bifilar arrangement.

Advanced Usage

• Bifilar Suspension: A specific technique for suspending an object (like a needle or mirror) using two parallel threads or filaments. This method prevents rotation around a vertical axis and provides torsional stability, commonly used in sensitive measuring instruments like galvanometers and torsion balances.
• Bifilar Winding: In electrical engineering, a method of winding two wires in parallel on a coil form. The wires are often connected so that their magnetic fields oppose each other, creating a non-inductive resistor or a precise current-measuring device.

Variants and Related Words

• Unifilar (adj.): Having or using a single filament or thread. (The opposite configuration to ).
• Trifilar (adj.): Having or using three filaments or threads.
• Filament (n.): A slender thread-like object or fiber, which is the core component of a bifilar design.

Synonyms

• Two-threaded
• Double-stranded (Note: This is a more general term and may not imply the precise parallel arrangement of "bifilar").

Antonyms

• Unifilar (single-threaded)
• Monofilament (single filament)
