中文摘要：

将颈部简化为含大血管的圆柱形组织，对颈动脉血管和含微、小血管的颈部组织分别建立热平衡模型．通过有限元求解，研究颈部表面的温度分布与颈动脉流量、颈部组织的物性以及环境参数的关联性．最后，实验研究兔子在一侧颈动脉结扎后的颈部两侧体表温度差，初步验证传热模型的合理性．

英文摘要：

The geometry of the neck was simplified as a cylinder tissue with two carotid arteries. A bioheat transfer model was set up, in which effects of the blood flow in the carotid arteries and the neck tissue on the heat transfer were taken as the convection and blood perfusion terms, respectively. The solution was obtained by the finite element method. Unsymmetrical temperature distribution of the neck surface was analyzed with respect to the blood flow in the carotid arteries, thermal properties of the neck tissue, and the environmental parameters. Finally, the neck surface temperature of a rabbit with one-side carotid artery ligated surgically was experimentally investigated, and the results can be used to validate the rationality of the proposed bioheat transfer model.
