Abstract:
A microwave oven having a cooking chamber, at least one heat outlet provided in a sidewall of the cooking chamber, at least one heat inlet provided in the center of the sidewall of the cooking chamber, and a convection assembly. The convection assembly is disposed on an external side of the sidewall of the cooking chamber, and includes a fan, a heating element, and at least one guide bracket which guides heat from the heating element through the at least one heat outlet and into the cooking chamber. According to this configuration, a microwave oven heats food more evenly and efficiently.
Abstract:
Embodiments provide a method of evaluating luminance of a light source, including acquiring first data including a plurality of luminance values by measuring luminance of the light source, converting the first data into second data corresponding to a plurality of unit cells, acquiring a moving average of the second data, and acquiring a ripple factor. The ripple factor is represented by (Draw-Ma)/Ma, where Draw is the second data and Ma is the moving average.

Abstract:
Disclosed is a method for producing a cerium dioxide nanopowder by flame spray pyrolysis. The method comprises dissolving a cerium compound in an organic solvent to prepare a precursor solution, atomizing the precursor solution into microdroplets using an ultrasonic atomizer, transferring the microdroplets together with an argon gas as a carrier gas to a central portion of a high-temperature diffusion flame burner, subjecting the microdroplets to pyrolysis and oxidation in the central portion of the diffusion flame burner to produce a cerium dioxide nanopowder, and collecting the cerium dioxide nanopowder using a collector. According to the method, a cerium dioxide nanopowder can be continuously produced on a large scale by flame spray pyrolysis. In addition, the particle size and uniformity of the cerium dioxide nanopowder can be controlled by appropriately selecting the kind of the solvent and the concentration of the raw material. Furthermore, flame spray pyrolysis allows the cerium dioxide to have a fluorite crystal structure.
