N2 - The surface resistance, Rs, of Bi2Sr2Ca1Cu2Oy (2212) strip lines prepared by the doctor blade method was measured by the strip-line resonance method. The highest TcR=0 of these strip lines measured by the conventional dc method was about 80 K. The Rs values were very sensitive to the surface and grain morphology of the films. It was verified through scanning electron microscope (SEM) observation and X-ray analysis that the Rs values of strip lines consisting of crystal grains whose c axes were oriented normal to substrate were smaller than those of strip lines with nonoriented grains. The values were about 6-22 mΩ at 70 K in the frequency range of 0.6-2.5 GHz. The Rs values were proportional to f1.0, in contradiction to the f2 dependence expected from the two-fluid model.
