But in the forepassed research , the people all abstracted the colloid in the water as the sphericity and explained it by the known theory of the colloid chemistry . moreover some people modified the result by the grain coefficient in the derivation of theory . but this assume had more difference on the observed phenomena in the experiment , so it was not perfect in theoretical speaking 關于絮凝的理論基礎在國外研究得比較多,但在過去的研究中,人們大都是將水中的膠體顆粒抽象為球形,用已有的膠體化學理論去加以解釋,并在理論推導中引入顆粒系數加以修正,這與實際實驗所觀察到的現象有較大的差別,從理論上說,是很不完善的。

In this paper , the aqueous sol of sno2 ultrafme particles were prepared by the colloid chemistry method . here we found that the partical properties of sno2 was concerned with experimental parameters such as type of peptization acid , sn4 + concentration , peptization time , peptization temperature , ageing time et al 本文采用膠體化學法制備了sno _ 2納米粒子水溶膠,細致研究了膠溶酸類型、 sn ~ ( 4 + )濃度、膠溶溫度、膠溶時間、陳化時間等對納米粒子性質的影響,并利用浸漬提拉法制備了sno _ 2超微粒子薄膜。

2 . a series of nanoparticles with different size can be obtained from just one reaction process based on the technology of time control and sampling in different phases as suggested by ostwald ripening theory in colloid chemistry . 3 2 .根據奧斯瓦爾德成熟理論( ostwaldripening ) ,采用時間控制、分段取樣方法,能夠在一次性生長過程中得到大小成系列分布的cds納米量子點。

According to the principle of surface and colloid chemistry , the pore structure and characteristics of tight sand gas reservoir are analyzed 摘要根據表面與膠體化學原理,分析了低滲致密砂巖氣藏的孔隙結構特徵、物性特徵以及它們之間的關系。
