precipitation reaction meaning in Chinese

沉淀反应
沉降反应
沈淀反应

Through the competition of ionization equilibrium of zno22 - and precipitation reaction , the nucleation and growth process of znse have been adjusted , and monodispersed znse semiconductor hollow microspheres are obtained . these microspheres were found to form through aggregation of small znse nanocrystals sizes of which could be finely tuned by temperature control . a novel gas - liquid interface aggregation mechanism was proposed and this idea might be generalized in other systems
以zno22 -阴离子提供锌源，利用它在强碱性溶液中缓慢释放出zn2 + ，并与se2 -之间的电荷排斥作用，成功地调节了反应动力学，获得了尺寸和分散性都非常均匀的微米级znse空心球，并实现了空心球内部粒子尺寸的调控，提出了新颖的气液界面团聚机理。
