[求助] 看有关七水合硫酸亚铁还原硝酸银制备纳米银的文献是看到这里不懂,球大神指教!

Once the two solutions are mixed, the nano Ag nuclei form, and the SO42− and the cations attach on the nano Ag nucleuses successively from the inner to the outer. So, the electrical double layers around the particles are formed in aqueous solutions. The thickness of the layers decreases with the increase of the ionic strength, which leads to the decrease of the range of the repulsion forces between the nano particles.

你知道我是谁

first, nano-size primary particles are nucleated in a supersaturated solution, and then aggregate to form larger uniform secondary particles. In the initial stage, the aqueous solution becomes black due to the formation
stabilizer of nano Ag particles, providing a “suitable” condition for the aggregation to form large grains in the
aqueous solution. Thus, the color of solution turns yellow slowly with the continuous consumption of Ag+
and the growth of Ag particles. This is in good accordance with the kinetic model proposed by PRIVMAN et al[14] and PARK et al[15].
这个是前一段话
哪位给解答一下
