| Abstract: | In this paper, wc study the biomathematical model of aneurxsm of circle of willis. We obatin approximation solutions of the system under the condition of weak damping and the, frequency-response equation in resonance case. By using frequency-response curves, the relationship between the frequency and amplitude of response is analized. Therefore the informatios about the enlargement and rupture of aneurysm can be obtained.The result of this paper includes the result of Ref. |
