我们已经分析了一个模型的毛细胞的毛束在低频率的运动。在该模型中，毛细胞器官被表示为一个系统的刚性机械结构所包围的流体。代表毛束的刚体铰接到代表感觉上皮的振动板。这些结构由第二振动板包围，该第二振动板代表顶盖结构。分析表明，流体的粘性和惯性性质是重要的事件在渐近低频。这些性质的相对重要性主要取决于盖层板块的存在和运动方式。因此，身体在低频下的角位移可以与基板位移、速度、加速度成正比，或者与其运动的简单积分成正比;函数关系取决于顶盖板的布置。
We have analyzed a model for the motion of hair bundles of hair cells at low frequencies. In the model, hair-cell organs are represented as a system of rigid mechanical structures surrounded by fluid. A rigid body, that represents a hair bundle, is hinged to a vibrating plate that represents the sensory epithelium. These structures are surrmounted by a second vibrating plate that represents a tectorial structure. The analysis shows that both viscous and inertial properties of the fluid are important event at asymptotically low frequencies. The relative importance of these properties depends critically on the presence and mode of motion of the tectorial plate. As a result, the angular displacement of the body at low frequencies can be proportional to basal plate displacement, velocity, acceleration, or to no simple integral of its motion; the functional relation depends upon the disposition of the tectorial plate.
