| Abstract: | The vibration of a chord is studied by using the printing point timer which can amplify the wave form of the chord. The results of this experiment are more accurate,moreover this experiment is done by using two different instruments which can develop students' thinking and can train the scientical test methods of students by using the comparative teaching method directly to test teaching. |
