The daily maximum/minimum temperature data at 740 stations in China from 1960 to 2005 were analyzed to reveal the statistical characteristics of record-breaking (RB) daily extreme temperature events in the past 46 years. The results indicate that the change amplitudes of future extreme temperatures differ evidently from place to place, showing a remarkable regional feature: future extreme high temperature...
Rogowski coils are special types of mutual inductors often used to measure large alternating and transient currents. Traditional handmade Rogowski coils lack accuracy and cannot be easily mass-produced. Two new structures of Rogowski coils based on printed circuit board are presented. Theoretical analyses on the mutual inductances of two designs are discussed. The measurements of basic characteristics,...
