Thereby improving the patient's blood circulation disorders and viscous state, to promote the absorption of inflammation, pelvic adhesiolysis, so that chronic inflammation can be cured.

This paper discusses identifiability of the initial state of one vibrating string with viscous damping at end point, where the velocity at this point is observed.

STF method with modification of viscous and bow up state was used for theory prediction, and model test for sea-keeping performance was done in towing tank.
