The equation correlating the concentration with thermal conductivity was presented . The time of measurement was 1 s. The method avoids the heat convection of liquid sample due to its rapidity and is promising for on line analysis in production control.展开更多

The Electric Field Integral Equation (EFIE) is used with the moment method to calculate the current distribution on the surface of the rivet. With the application of Gaussian integral corresponding triangular cell, the time to fill the Z matrix is greatly reduced. Finally, the RCS of a type of rivet on aircraft is analyzed.展开更多
