Exempel på tungsten

• Second, the intensity of the tungsten halogen lamps could be reduced in order to lower the thermal heating of plant canopies.

• Since the beam's energy deposition will melt and evaporate even tungsten, non-intercepting diagnostics are required.

• Because of their specific structural, electrical, mechanical and optical properties, tungsten- titanium thin films 0 coatings have many promising applications.

• The insulation times of aluminum and tungsten wires are proportional to the length.

• A higher kinetic energy of the tungsten ions means that the plasma streams inside the array, including the region near the axis, are collisionless.

• Clearly no shock will form at the tungsten- carbon boundary, but interpenetration of the two species will occur.

• The secondary is suspended off of the tungsten wires and becomes par t of the power feed to supply current to the upper pinch.

• Large and fresh samples were split, jaw-crushed and reduced to powder in a tungsten carbide shatterbox.

• This drive contained a tungsten-in-glass microelectrode which passed out of the guard tube and into the brain.

• Insulated tungsten electrodes were lowered through the dura into the thalamus.

• The resistance of tungsten wire at room temperature is two times higher than that of aluminum wire, and three times higher than that of copper.

• Three different types of microelectrodes were utilized: varnish-insulated tungsten, glass pipette, or glass-coated platinum-iridium.

• Dormancy may be induced by long days at least when tungsten bulbs are used for daylength extension.

• In this long-pulse mode, tungsten wire arrays radiated very effectively.

• The tungsten-tip cathode in the diode had diameter 4 mm and the stainless-steel anode had aperture 20 mm.
