摘　　要：本文通过用焓模型求解非线性生物传热方程,研究了低温外科中冷冻探针周围组织的瞬态温度场,使生物组织的“冷冻损伤”形状、成长速率及最终稳态冷冻区域大小得以确定.本文旨在一方面为低温外科提供必要的理论依据,另一方面使一般相变导热问题的焓法求解得以进一步深入及推广.The transient temperature field around a cryoprobe was investigated by applying the enthalpy model to solve the nonlinear bio-equation; therefore the shape ,rate of growth and ultimate size of the cryolesion was determined, this paper intends to provide foundamental information for cryosurgery,and to extend the application of enthalpy model.
