paraboloidal การใช้

• As the tray spins the liquid forms a paraboloidal surface of essentially unlimited size.
• It remains paraboloidal, but its focal length and other parameters change as it tilts.
• The most common liquid used is paraboloidal shape regardless of the container's shape.
• A darker streak, in a horseshoe or paraboloidal shape, surrounds the bright area.
• The mirror is never exactly paraboloidal, but it is always close enough for cooking purposes.
• By placing the container away from the axis, off-axis paraboloidal segments can be cast.
• This employed sophisticated hyperbolic-paraboloidal platforms to allow large trees to be planted on its roof.
• Paraboloidal reflectors generate high temperatures and cook quickly, but require frequent adjustment and supervision for safe operation.
• When the rotation is stopped, the glass is solid, so the paraboloidal shape of its top surface is preserved.
• This rotation technique is sometimes used to make paraboloidal mirrors for astronomical telescopes, and has also been used for solar cookers.
• Although paraboloidal solar cookers can cook as well as or better than a conventional stove, they are difficult to construct by hand.
• The " gereformeerde kerk " with its paraboloidal roof was built in 1925, based on the design by architect W . van Straten.
• Use of a paraboloidal collimator, has produced 2 arc sec image quality with minimal astigmatism along the central 2-3 arc min.
• Spherical reflectors operate much like paraboloidal reflectors, such that the axis of symmetry is pointed towards the sun so that light is concentrated to a focus.
• If the surface is paraboloidal, the mirror usually looks like a doughnut or lozenge although the exact appearance depends on the exact position of the knife edge.
• This configuration utilizes a two-axis feed flat mirror to reflect starlight into a fixed paraboloid of revolution ( paraboloidal ) mirror, usually with a horizontal optical axis.
• Radar-dark ( i . e ., smooth ) paraboloidal streaks were observed around craters in earlier Magellan images, but this is a rare bright crater streak.
• In 1636 Marin Mersenne proposed a telescope consisting of a paraboloidal primary mirror and a paraboloidal secondary mirror bouncing the image through a hole in the primary, solving the problem of viewing the image.

• This equation has important applications in the science of optics, where it provides solutions that describe the propagation of electromagnetic waves ( light ) in the form of either paraboloidal waves or Gaussian beams.
