在这份报纸,在 Corti (OC ) 的机关上的 Corti (TC ) 的一条隧道的液体的效果被学习。包括基部的膜(BM ) 的一个三维的 OC 模型,构成覆盖物的膜(TM ) ,内部、外部的毛细胞(OHC ) ,和网状的薄板(RL ) 被 COMSOL 建立。一个起始的压力在 TC 被用于液体。结构的频率反应被分析,并且 BM 的排水量被完成。结果在对试验性的数据的好同意,证实有限元素模型的有效性。基于模型,在 OC 上的 TC 的液体的效果被学习。结果看那压力坡度是否在液体是不在的,随起始的液体压力的增加, BM 的排水量增加。当起始的液体压力增加到某个价值时, BM 的排水量的增加率不管多么变得很慢。液体的运动放大 BM 运动。而且,液体的运动能加强 OHC 的运动和 stereocilia 的 shear 运动,特别在扩大效果在到达一座山峰的典型频率的附近。不过,在液体的一个压力坡度影响 BM 运动。
In this paper, the effect of fluid in a tunnel of Corti (TC) on organ of Corti (OC) is studied. A three-dimensional OC model including basilar membrane (BM), tectorial membrane (TM), inner and outer hair cells (OHCs), and reticular lamina (RL) is established by COMSOL. An initial pressure is applied to the fluid in the TC. The frequency response of the structure is analyzed, and the displacement of the BM is achieved. The results are in good agreement with the experimental data, confirming validity of the finite element model. Based on the model, the effect of fluid in the TC on the OC is studied. The results show that, when the pressure gradient is absent in the fluid, with the increase of the initial fluid pressure, the displacement of the BM increases. However, when the initial fluid pressure increases to a certain value, the increase rate of the displacement of the BM becomes very slow. The movement of the fluid amplifies the BM movement. Furthermore, the movement of the fluid can strengthen the movement of the OHCs and the shear movement of the stereocilia, especially in the vicinity of the characteristic frequency at which the amplification effect reaches a peak. Nevertheless, a pressure gradient in the fluid affects the BM movement.
