We propose a new way of rewriting the two dimensional Euler equations and derive an original canonical characteristic relation based on the characteristic theory of hyperbolic systems.This relation contains the derivatives strictly along the bicharacteristic directions,and can be viewed as the 2D extension of the characteristic relation in 1D case.
