| Abstract: | A process is analyzed that the oil drop moved from stationary to uniform motion,and the time of this process is discussed in this paper.A conception of acceleration relaxation time has been imparted to students in the experiment teaching.An important factor which puzzles students in the measuring process has been eliminated. |

| Keywords: | gravitation viscous resistance balancing voltage relaxation time |
