中文摘要：

本文使用有限元方法迎风格式数值研究了热显著性血管影响下的纳米低温手术过程,重点分析了热显著性血管和纳米颗粒的存在对于低温手术过程的影响。结果表明：热显著性血管在纳米低温手术过程中依然表现出显著的加热效果,但相对于不使用纳米颗粒的传统低温手术而言,其加热作用有所降低。基于此,拟深入研究纳米低温手术过程血管网的热效应,并对血管网存在条件下的纳米低温手术过程进行优化。

英文摘要：

An up-wind finite element approach was developed to simulate of the nano-cryosurgical process in target tissues with thermal significant blood vessels（TSBVs）.The numerical results indicated that the heating feature of the blood flow is still obvious in nano-cryosurgery process,while the freezing efficiency was significantly improved compared with the conventional cryosurgery.This numerical method can provided an effective approach to optimize the nano-cryosurgery process in the presence of the TSBVs.
