【Abstract】 This paper analyzes the principle of vibrator,tests it in different conditions,and finds out the relation between the damp and the resistance:ζ=f(R).The optimal damp depends on the value of R.Another method for calculationg the resistance by R is offered to make the vibrator have isoelectricity for different apparatus,so as to greatly increase the oscillograph fidelity.更多还原
