| 摘 要： | 在已有的脑Willis环研究的基础上，建立了反映脑循环血液脉动特性的集中参数模型并给出了参数求解方法，通过对30例临床数据的计算发现理论值与大部分疾病诊断结果相吻合，这不仅说明模型是符合生理实际的，还说明模型参数的求解方法在临床上是切实可行的。

| Abstract: | According to the anatomy of cerebrovascular system and the theory of hemodynamics, a lumped parameter model describing the flow in the Willis circle was set up. Considering the electrical equivalent circuit of this model, the governing equations and the method to calculate the dynamic index were proposed. Comparing with the clinical data from Huashang Hospital, most calculating results agreed with the clinical diagnoses. That showed this calulating method may help doctors to confirm their diagnoses. |
