Abstract: The present invention relates to a device for evaluating the performance of a superconductive coil for a high-temperature superconductive rotary machine and a method for evaluating the performance of a superconductive coil thereby. The technical gist of the present invention is to provide schemes for evaluating the stability of a superconductive coil and verifying the reliability thereof, to evaluate/confirm whether or not the same can be commercialized, and to evaluate/confirm the threshold current of a superconductive wire for manufacturing a superconductive coil or the upper limit of the operating current thereof, and is characterized in that the electromagnetic, thermal, and mechanical performances of a superconductive coil for a second-generation high-temperature superconductive rotary machine can be evaluated.

Abstract: A particulate matter reduction apparatus for a diesel engine, which can reduce particulate matter in a convenient manner with a relatively simple structure, while preventing the shortening of the lifespan of a filter and improving particulate matter burning efficiency, is provided. The particulate matter reduction apparatus includes a housing configured to be placed on a flow path into which exhaust gas is discharged from the diesel engine, a filter configured to collect particulate matter contained in the exhaust gas that flows in the housing, electrodes configured to transmit electronic signals to the filter, and a control unit configured to control the electric signals provided to the electrodes. The particulate matter reduction apparatus is advantageous in that particulate matter is burnt and removed by directly heating the filter. In addition, the apparatus is more convenient, compared to a system which requires a filter to be separated and cleaned.
