Abstract: By applying the derived integral identity of vortex motion in the vortex dynamic equation, the paper established the integral equations of vortex motion under external force potentiality for the quatitative mass and controlled zone respectively. The equations and the material derivative of the total arrow of vortex intensity are discussed and the conclusions can be for reference in further studying of macrodynamic behaviour of vortex motion.

Key words: incompressible and viscous fluid vortex motion total arrow of vortex intensity material derivative.
