摘要：

We have searched for large deviations from Newtonian gravity by means of a finite-frequency microcantilever-based experiment. Our data eliminate from consideration mechanisms of deviation that posit strengths similar to10(4) times Newtonian gravity at length scales of 20 mum. This measurement is 3 orders of magnitude more sensitive than others that provide constraints at similar length scales.
