摘要：
The Stokes flow through a tube which is periodically constricted is studied by using eigenfunction expansions and matching. Both streamlines and pressure drops are computed. It is found that if straight sections of a tube are long enough, the total pressure drop is a sum of Poiseuille pressure drops and the excess pressure drops due to the diameter changes.
