1. No reprecipitation was abserved on cooling in these two steels.

2. The influences of reprecipitation conditions on the preparation of nanoparticles were analyzed on the basis of this model.

3. The mechanism of oxygen isotope exchange between alkali feldspar and fluid is mainly dissolution reprecipitation.

4. The granularity, morphology and existent states of gold can imply the migration and enrichment degree and the reprecipitation mechanism of gold.

5. The deformation of olivine and pyroxene in the rock is the recrystallized process from coarse to fine grain, the spinel has obvious dissolution, migration and reprecipitation.

6. Solid and tubular one-dimensional (1D) submicrometer scaled structures were prepared from naphthalene-1,4-dicarbonitrile (DCN) with a reprecipitation method.
