In SDS-CaCl_2 system, the adsorption of Ca~(2+) ions on micellar surface can not result in the charge neutralization and there is no hydroxide group bridging effect in this system, so the surfaetant can not be flocculated in form of micelles.

在SDS-CaCl_2体系中，Ca~(2+)的吸附作用并未导致胶束表面电荷的中和，也不存在羟基架桥的作用，故该体系中的表面活性剂不能以胶束形式沉淀。

In SDS-FeCl_3 and SDS-PAC systems, no special chemical complexation reaction exists between the dominant species of metal ions and SDS, so no redissolufion phenomenon can be observed at high flocculant concentrations in these two systems. Secondly, when calcium or magnesium salt, which is very ubiquitous in natural water body, is added into surfactant micellar solution, surfactant can not be flocculated in micellar form.

但在SDS-FeCl_3及SDS-PAC体系中，金属离子主要存在物种与SDS间无特殊的化学络合作用存在，故这两个体系中在高混凝剂浓度下也观察不到沉淀重新溶解的现象。2向表面活性剂胶束溶液中加入天然水体中常见的钙盐或镁盐，表面活性剂不能以胶束形式被沉淀。

It can be assumed that, the Mg~(2+) ions remain as hydrated ion forms when adsorbed onto micellar surface because of its strong hydration effect, so it can not neutralize the micellar surface charge effectively, make it destabilized and flocculated, neither can it form low-solubility salt with SDS as in SDS-CaCl_2 system.

认为是由于Mg~(2+)离子的水合作用比较强，导致其以水合离子的形式在胶束表面吸附，未能有效地接近并中和胶束表面电荷，也未能像Ca~(2+)那样，与SDS形成难溶盐而结晶沉淀。

Results suggest that, firstly, when inorganic flocculant Al_2(SO_4_3, FeCl_3 or PAC is added into surfactant micellar solution, surfactant is flocculated in micellar form.

结果表明，1向表面活性剂胶束溶液中加入无机混凝剂Al_2(SO_4_3、FeCl_3或PAC，表面活性剂以胶束形态被混凝沉淀。

Most of cases had following characteristic MRI findings: olfactory nerve tumors were often located at anterior cranial fossae and appeared as lobulated mass; optic nerve tumors presented as nerve thickening; tregemimal nerve tumors usually grew across the middle and posterior cranial fossae and appeared as a collar-button appearance; tumors of Ⅷ nerves were nerve thickening and located at CPA; facial nerve tumor was located in mastoid with irregular shape; hypoglossal nerve tumors, vagus nerve tumors and hypoglossal nerve tumors were often located in an enlarged jugular foramen.

脑神经肿瘤发生在特定部位，大部分有特征性MRI表现：嗅神经肿瘤多位于颅前窝，呈分叶状；视神经肿瘤多有神经束增粗；三叉神经肿瘤骑跨颅中、后窝生长，呈哑铃状；听神经肿瘤为第Ⅶ、Ⅷ神经束增粗，并与桥小脑角区肿瘤相连；面神经肿瘤位于乳头内，形态不规则；舌咽、迷走、舌下神经肿瘤位于颈静脉孔区，往往伴有颈静脉孔扩大。
