| 摘 要： | 实验验证了Ｒａｙｌｅｉｇｈ－Ｍｉｅ光散射理论在测定胶体颗粒尺寸上的应用，并提出利用稳定胶体浊度的测定来确定该胶体颗粒尺寸的精确方法。对于直径小于１μｍ的颗粒，这种方法很可靠。结合光散射理论和Ｓｍｏｌｕｃｋｗｓｋｉ混凝速率理论建立了混凝胶体的浊度变化与混凝速率的定量关系，并提出混凝速率和胶体稳定性的精确测定方法。用这种方法对均匀胶体的混凝速率进行了测定，并验证了Ｓｍｏｌｕｃｋｗｓｋｉ混凝理论。

| Abstract: | Rayleig-Mie light scattering theory was verified in its application to the determination of Brownian particle sizes and coagulation rates. A quantitative relationship between initial variation rates of turbidity and coagulation rates was established by a combination of Rayleigh-Mie theory and Smoluckwski perikinetic coagulation theory and tested experimentally. |
