%X The cerebravascular disease is very related with the abnormal hemodynamic state of cerebral circulation. There are some different characteristics between the cerebral circulation and the systemic circulation of human.In clinical application, it is necessary to set up a hemodynamics model which not only has the principal characteristics of the cerebral circulation but also can be used easily to analyse the cerebravascular dynamics index(CVDI). According to the steady flow model of Willis circulation, we set up a lumped parameters model for analysing the cerebral circulation pulstile flow, and get its governed equations as well as its solving method. Preliminary results of our experiment show that the theoretical conclusion agree with the experiment data. It reveals that the present analysis is consistent with the physiological phenomena, and may offer a delicate hemodynamic model for cerebral circulation research.
