dielectric heating การใช้

• This is also known as electron cyclotron resonance heating or Dielectric heating.
• Dielectric heating involves the heating of electrically insulating materials by dielectric loss.
• Methods of electric heating include resistance heating, electric arc heating, induction heating, and dielectric heating.
• It's just that Dielectric heating works better on water then other substances commonly contained in food.
• :: The reason microwaves are able to heat water is because of something called dielectric heating.
• When injury from exposure to microwaves occurs, it usually results from dielectric heating induced in the body.
• Dielectric heating certainly would be practical.
• Water is a dipole molecule you will often put in your microwave, and, through dielectric heating, cooks your food.
• Changing " electric " dipole fields, as such, are used commercially as near-fields mainly as a source of dielectric heating.
• :Another possibility would be to merge it to Dielectric heating # Microwave heating . talk ) 10 : 13, 11 October 2016 ( UTC)
• Dielectric heating at low frequencies, as a near-field effect, requires a distance from electromagnetic radiator to absorber of less than } } H " of a wavelength.
• Is it possible to heat rock like granite by using dielectric heating or induction heating . . ? talk ) 05 : 46, 1 November 2012 ( UTC)
• Dielectric loss is caused when the insulating material inside the transmission line absorbs energy from the alternating electric field and converts it to heat ( see dielectric heating ).
• The " high-frequency dielectric heating apparatus " invented by Spencer was patented in 1953, and the first ovens were named " radar ranges " in reference to their discovery.
• Diathermy is used by some as a synonym for electrosurgery but in other contexts diathermy means dielectric heating, produced by rotation of molecular dipoles in a high frequency electromagnetic field.
• In agriculture, RF dielectric heating has been widely tested and is increasingly used as a way to kill pests in certain food crops after harvest, such as walnuts still in the shell.
• Dielectric heating of liquid water is also temperature-dependent : At 0 癈, dielectric loss is greatest at a field frequency of about 10 GHz, and for higher water temperatures at higher field frequencies.
• Shigeru Nakajima, a younger brother of Yoji Ito and a scientist at the Japan Radio Company ( JRC ), was also investigating magnetrons, primarily for the medical dielectric heating ( diathermy ) market.
• A microwave oven passes ( non-ionizing ) microwave radiation at a frequency near [ [ ISM band | ] ] through food, causing dielectric heating primarily by absorption of the energy in water.
• Nevertheless, the primary heating effect of all types of electromagnetic fields at both radio and microwave frequencies occurs via the dielectric heating effect, as polarized molecules are affected by a rapidly alternating electric field.
