This article introduced a solution for the difficult question in the C Ianguage programming:the graph printing question,and elaborated in detail the specific measures how to solve this double circulation question using the algebra method.

A new restoration algorithm based on double circulations and alternant iterations is proposed to restore the object image effectively from a few frames of turbulence-degraded images.

The formed conditions of a double-recirculation flow pattern (DRFP) in a slab con- tinuous casting mold with blowing argon gas were quantitive described using the Lagrange multi-phase flow model,and the prediction was validated by the water model.
