hertzian การใช้

• He has produced a comprehensive glossary on Hertzian fractures and related terms.
• For example, Cheng 1989 states that the radiation resistance of a Hertzian dipole is
• Early on after their discovery, radio waves were referred to as " Hertzian waves ".
• But again, the Hertzian dipole is meant only as a theoretical construct for antenna analysis.
• The Hertzian oscillator loses mass in the emission process, and momentum is conserved in any frame.
• The discovery of these " Hertzian waves " ( radio waves ) prompted many experiments by physicists.
• The stresses between the ball and the plate are described in more detail by Hertzian stress theory.
• For a sphere of radius R and elastic constants E, \ nu this Hertzian solution reads:
• An IP user is adding links to a fringe physics site on " Hertzian radiation " to articles on, and.
• The history of the Hertzian waves shows us the ubiquity of these vibrations in the external world, imperceptible to our senses.
• These papers were read by English physicist Oliver Lodge who saw this as a way to build a much improved Hertzian wave detector.
• That same year Italian inventor Guglielmo Marconi demonstrated a wireless telegraphy system using Hertzian waves ( radio ), based on a coherer.
• Likewise, a Hertzian ( short ) dipole couples directly with the electric field and is relatively immune to locally produced magnetic noise.
• James Byous, working independently ( at privately funded Dowd Research, Savannah, Georgia USA ) has made a protracted study of Hertzian cones.
• This and heat and friction losses are influences that can be included in the Hertzian equations to make them more general and for subsequent collisions.
• The first primitive radio transmitters ( called Hertzian oscillators ) were built by German physicist Heinrich Hertz in 1887 during his pioneering investigations of radio waves.
• Consequently, it can be seen that the radiation resistance computed for the short dipole is one quarter of that computed above for the Hertzian dipole.
• In 1958 K . L . Johnson presented an approximate approach for the 3D frictional problem with Hertzian geometry, with either lateral or spin creepage.
• A "'Hertzian cone "'is the cone produced when an object passes through a solid, such as a bullet through glass.
• At that time, the word'coherer', coined by Lodge, was used in the English-speaking world for Hertzian wave receivers or detectors.
