| 摘 要： | 根据某鼻腔疾病患者的CT图像，用表面重建的方法对该患者的鼻腔结构进行三维重建，根据统计得出的呼吸潮气量以及呼吸周期假设一个呼吸周期内的鼻腔中气流流速的变化。用有限元的方法对鼻腔域中的气体流动进行了数值模拟及分析，并把得到的结果与医学文献中记载的数据相比较，说明本文计算结果是可信的。从文中的数值结果可以定量得到人体呼吸过程中，气体流场在鼻腔中的分布。 |

| Abstract: | The nasal cavity structure of one patient was reconstructed by the method of surface rendering based on his CT images, In a respiratory period the change of air flux in the nasal cavity was supposed based on the tidal volume and the respiratory period gained by statistical method. The digital simulation and the analysis of the airflow in the nasal cavity was made by the FEA method and the result was compared with the data from literatures. The comparison indicates that the result is confident. From the result we can observe the airflow distribution quantitatively in the nasal cavity in the period of respiration. |
| Keywords: | Nasal cavity Nosepiece Three-dimenslonal reconstruction Digital simulation of airflow |
