摘要：

Aqueous solutions of the ionic compound NaClO3 are not optically active. These solutions can be made to supersaturate and precipitate chiral crystals of NaClO3. The undisturbed solution yields statistically equal numbers of 1- and d-crystals. Stirring the solution causes breakage of chiral symmetry and very high enantiomeric excesses can be obtained. A computer program has been developed which closely simulates this phenomenon. A kinetic mechanism for the origin of chiral asymmetry in this system is discussed in relation to the current experimental and simulation data.
