gyro-
  لر-   
ler-

Fr.: gyro-   

A combining form meaning "ring, circle, spiral," used in the formation of compound words: → gyroscope, → gyrofrequency, → gyroradius, → gyrate.

From Gk. gyros "circle, ring;" PIE base *geu- "to bend, curve."

From leridan, → gyrate.

gyrofrequency
  لِربسامد   
lerbasâmad

Fr.: fréquence gyromagnétique   

The frequency with which an electron or other charged particle executes spiral gyrations in moving across a magnetic field.

gyro-; → frequency.

gyroradius
  لرشعاع   
leršo'â'

Fr.: gyrorayon   

Same as → Larmor radius.

gyro-; → radius.

gyroscope
  لِرنما، چرخش‌نما   
lernemâ, carxešnemâ

Fr.: gyroscope   

A device for measuring or maintaining orientation. Consisting of a rotating wheel so mounted that its axis can turn freely in certain or all directions, it is based on the principle of conservation of angular momentum. In physics this is also known as gyroscopic inertia or rigidity in space.

Gyroscope, from gyro-, → gyrate + → -scope.

Lernemâ, from ler, → gyrate, + -nemâ-scope; carxešnemâ, from carxešrotation + -nemâ.

GZK cutoff
  بره‌ی ِ گریسن-زاتسپین-کوزمین   
bore-ye Greisen-Zatsepin-Kuzmin

Fr.: limite de Greisen-Zatsepin-Kuzmin   

Same as → Greisen-Zatsepin-Kuzmin cutoff.

Greisen-Zatsepin-Kuzmin cutoff.
