用Si_3N_4悬臂梁探针对具有不同表面自由能(30∼~65dyn/cm)的无机固体表面进行了探测。结果表明，悬臂梁尖端接触后离开固体表面时产生的引力(∼10-7N)对表面自由能的行为比悬臂梁尖端向固体表面移动时产生的引力(∼10-9N)更敏感。文中还讨论了悬臂梁的弹性势能与尖端-表面系统的粘着能之间的关系。
Inorganic solid surfaces which have various surface free energies, 30∼65 dyn/cm, were probed using a Si3N4 cantilever tip. It was found that the attractive force (∼10-7 N), which is generated when a cantilever tip moves away from a solid surface after making contact, is more sensitive to the behavior of surface free energy than that (∼10-9 N) which is generated when the tip moves toward the surface. The relationship between the elastic potential energy of the cantilever and the adhesion energy of the tip-surface system is also discussed.
