Dielectric gas - Wikipedia

A dielectric gas, or insulating gas, is a dielectric material in gaseous state. Its main purpose is to prevent or rapidly quench electric discharges.Dielectric gases are used as electrical insulators in high voltage applications, e.g. transformers, circuit breakers (namely sulfur hexafluoride circuit breakers), switchgear (namely high voltage switchgear), radar waveguides, etc.Get price

Dielectric Analysis - NETZSCH Thermal Academy

Dielectric Analysis (DEA) Dielectric Analysis (DEA, also known as Dielectric Thermal Analysis (DETA), is a technique for monitoring changes in the viscosity and cure state of thermo-setting resins, adhesives, paints, composites and other kinds of polymers or organic substances by measuring variations in their dielectric properties.Get price

Dielectric Constant of Ionic Solutions: A Field-Theory Approach

value of =" 0 is ion specific and ranges from 8M1 to 20 M 1, for concentrations up to 1.5 M. At higher c s values, noticeable deviations from linearity are observed and are due to ion-ion interactions [18–20]. In this Letter we go beyond the standard PB theory and investigate the microscopic origin of the dielectric decre-ment.Get price

Why the Battle for Hamburger Hill Was So Controversial - HISTORY

How The Battle of Hamburger Hill Got Its NameHamburger Hill’s Forested Terrain Posed ChallengesThe Battle Went on For DaysThe U.S Military Quickly Pulled BackControversy Began on Homefront Before The Battle Had EndedHamburger Hill Changed U.S Military TacticsHamburger HillLegacyThe hill and the battle got its infamous nickname thanks to the intensity of the fighting there, in what soldiers dubbed a “human meat grinder.” Sergeant James Spears, a 19 year old who fought in the battle, told reporters, “Have you ever been inside a hamburger machine? We just got cut to pieces by extremely accurate machine-gun fire.” The name “Hamburger Hill” caught on quickly, in part, because so many journalists flocked to the area to report on the battle. High causalities resulted, in part, from a shift in the North Vietnamese fighting strategy. “They know they don’t have to win the war, they just have to outlast the United States,” says Meredith Lair, associate professor of history at George Madison University. “It’s not about achieving a decisive victory, but to inflict damage and wreak havoc with the political situation in the United States.” Bob Harkins, who was the commanding officer of Alpha Company, 3rd Battalion, 187th Regiment, elaborated: “They read the U.S. newspape...Get price
