英文摘要：

Based on summarizing of impinging stream technology and high gravity technology, the action mechanism of micromixing effect on precipitation was analyzed and the cause of IS-RPB reactor in enhancing micromixing effect on precipitation was discussed. Supersaturation and its distribution were the main factors in determining the particles size and distribution （PSI））. And characteristic diffusion time was adhibited to judge the controlling factor of the nucleation process. The results indicated that compared to characteristic nucleation time of 3.8 s, characteristic diffusion time of 0.04-5 ms satisfies to the condition of micromixing. Controlling operation conditions, spindleβ-Cu partides with size range from 0.12μm to 5μm can be obtained. The average particle size of the product is 610nm and specific surface area is 11. 626 5m^2/g.
