The experimental group underwent an incision inferior to the pinna, and the cochleas were destoried with a drill through the bulla bilaterally. The control group underwent only an incision without cochlea ablation.

实验组采用耳后径路开放听泡，用微型钻在耳蜗表面钻孔损毁双侧耳蜗结构；对照组仅做耳后切口不破坏耳蜗结构。

Results In three Hank's solution infused cochleas, the thresholds of IC potential were kept in the normal level and no hair cell loss was found 14 days after the beginning of the infusion, suggested that the pump implantation and Hank's solution infusion had no significant effects on the cochlear functions. In contrast, threshold shifts of IC potentials and hair cell loss were found in two BSO infused animals, suggested that the infused solution had distributed into the whole cochlea.

结果 应用渗透压泵耳蜗灌流Hank液后，下丘电位阈值维持正常，耳蜗毛细胞无损伤；灌流BSO液14天后，所测频率(1、 2、 4和8 kHz)的下丘电位阈值平均升高28 dB，内耳毛细胞平均缺失39.3%，缺失分布于耳蜗各回，表明渗透压泵工作良好。

At the end, the prototype of the cylindrical surface envelope globoidal worm gearing with rolling friction and point engagement is manufactured successfully and the experiment of the prototype is performed, which shows that above-mentioned theory and technology for such mechanisms are correct and feasible, and also shows that the performances for such mechanisms are largely better than other worm gearings.

But as for impellers and diffusers, not much research was carried on volutes and their design is still based on traditional one-dimensional method.

但是相对于叶轮扩压器而言，关于蜗壳的研究比较少，并且蜗壳的设计也停留在传统的一维设计方法上，此设计方法不符合实际流动情况，导致蜗壳内流体参数不均匀性的增强，进而影响叶轮和扩压器内的流动，降低压缩机整体性能。
