Exempel på hur du använder VACUUM i en mening

• Through styling and design of the exterior and interior of anything from large structures to small objects, including how people look (clothing, fashion, and jewelry), Art Deco has influenced bridges, buildings (from skyscrapers to cinemas), ships, ocean liners, trains, cars, trucks, buses, furniture, and everyday objects including radios and vacuum cleaners.
• The wars of the Diadochi witnessed the fall of the Argead dynasty in Macedon resulting in a power vacuum, which the Antigonid and Antipatrid dynasties sought to occupy.
• Historically, it was used as a getter for vacuum tubes and in oxide form as the emissive coating on indirectly heated cathodes.
• Distillation cow, a piece of glassware that allows fractions to be collected without breaking vacuum.
• A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams that are manipulated to display images on a phosphorescent screen.
• Chemical vapor deposition (CVD) is a vacuum deposition method used to produce high-quality, and high-performance, solid materials.
• The technique involves the expansion of a gas or mixture of gases through a de Laval nozzle from a high-pressure reservoir into a vacuum chamber.
• The Crookes radiometer (also known as a light mill) consists of an airtight glass bulb containing a partial vacuum, with a set of vanes which are mounted on a spindle inside.
• Compactrons are a type of vacuum tube, which contain multiple electrode structures packed into a single enclosure.
• They were the first type of high vacuum pumps operating in the regime of free molecular flow, where the movement of the gas molecules can be better understood as diffusion than by conventional fluid dynamics.
• In 1926 Antonio Cavalieri Ducati and his three sons, Adriano, Marcello, and Bruno, founded Società Scientifica Radiobrevetti Ducati (SSR Ducati) in Bologna to produce vacuum tubes, condensers, and other radio components.
• In physics, an electronvolt (symbol eV), also written electron-volt and electron volt, is the measure of an amount of kinetic energy gained by a single electron accelerating through an electric potential difference of one volt in vacuum.
• The first-generation 700s were based on vacuum tubes, while the later, second-generation 7000s used transistors.
• In their setup, the vacuum has the usual 3 dimensions of space and one dimension of time but with another microscopic extra spatial dimension in the shape of a tiny circle.
• Like all alkali metals, lithium is highly reactive and flammable, and must be stored in vacuum, inert atmosphere, or inert liquid such as purified kerosene or mineral oil.
• It was invoked to explain the ability of the apparently wave-based light to propagate through empty space (a vacuum), something that waves should not be able to do.
• Instruments used to measure and display pressure mechanically are called pressure gauges, vacuum gauges or compound gauges (vacuum & pressure).
• The cavity magnetron is a high-power vacuum tube used in early radar systems and subsequently in microwave ovens and in linear particle accelerators.
• Victor Schumann discovered vacuum ultraviolet radiation in 1893, Wilhelm Röntgen discovered X-rays in 1895, Henri Becquerel discovered radioactivity in 1896, and, in 1897, J.
• Due to their small size, there was no space to include a vacuum fitting to evacuate the tube; instead, nuvistors were assembled and processed in a vacuum chamber with simple robotic devices.
