We have analyzed the emerging precipitate pattern of calcium-oxalate in a flow system. The circular symmetry is broken because of the hydrodynamic instability at the tip of the underlying gravity current. The presence of a concentration gradient maintained by the flow leads to the enrichment of the thermodynamically unstable calcium oxalate dihydrate form.
我们已经分析了在流体系中出现的草酸钙沉淀模式。由于底层重力流尖端的流体动力不稳定性，圆形对称性被打破。流动维持的浓度梯度的存在导致热力学不稳定的二水草酸钙形式的富集。
