By choosing an appropriate monitor function, the density of mesh points near the critical points can be bigger than that near other points on the minimal energy path.

Results: Typical CT findings of cl in children included: cystic mass with smooth margins, uniformed density, thin walls, minimal rim enhancement and lack of enhancement in cystic Spaces.

And the surface velocity of molten metal in the mold was minimal at a magnetic flux density of 0.5 t, it agreed well with measured surface level fluctuations in water modeling.
