Source sentences:
text: When the distance between the probe and the sample is brought to the range where atomic force may be detected, while a cantilever is excited in its natural eigen frequency (f 0 ), a phenomenon occurs that the resonance frequency (f) of the cantilever shifts from its original resonance frequency (natural eigen frequency).
text: The initial resonance frequency (f) of the active cantilever was 28.026 kHz, while the frequency of reference cantilever was 40.351 kHz.
