摘要：

We report the measurement of average response of micromechanical resonators to very small driving forces, with a corresponding energy resolution of the order of h omega(0), the energy quantum of the classical resonator system. The measured coherent excitation is more than an order of magnitude weaker than the random thermal fluctuations. (C) 2000 Elsevier Science B.V. All rights reserved.
