附着损耗可能在限制微/纳米机械振荡器的品质因数方面发挥作用。这方面的现有理论结果适用于高度理想化的场景。该理论在两个重要方向上得到了扩展：悬臂梁的宽度相对于波长而言被认为是小的，而不是大的；底座被允许具有有限的厚度。这些延期在许多情况下导致依恋损失估计数量级的重大变化。给出了涵盖大部分参数范围的Q(-1)的简单公式。
Attachment losses can play a role in limiting the quality factors of micro/nanomechanical oscillators. The existing theoretical results in this regard are applicable to highly idealized scenarios. The theory has been extended in two important directions: the width of the cantilever is considered to be small relative to a wavelength as opposed to large, and the base is allowed to have finite thickness. These extensions result in significant, in many cases order of magnitude, changes in the estimates of attachment loss. Simple formulas for Q(-1) covering most of the parameter range are given.
