摘要：

We have recently reported the breaking of chiral symmetry in stirred crystallization. One of the most important aspect of the mechanism that leads to the symmetry breaking is the phenomenon of secondary nucleation. The empirical expressions currently used for the rates of secondary nucleation are not based on a clear physical model. We present here some experimental observations on NaClO3 crystallization that gives us a physical model to develop an expression for the rates. Such expressions are important for a quantitative and statistical understanding of the phenomenon of chiral symmetry breaking in stirred crystallization.
