摘要：
In this paper, the principle of maximum power losses for the incompressible visous fluid proposed by professor Chien Weizang in reference[1] is further extended to the hydrodynamic problem of the non-Newtonian fluid with constive law expressed as . The constraint conditions of variation are eliminated by the method of identified Lagrangian multiplier and a generalized variational principle is established.
