Soils dominated by 2:1 clays(montmorillonite, vermiculite, illite), more frequently found in temperate zones, but also present in tropical and subtropical areas; behave different from the typical tropical red soils (Ultisols and Oxisols dominated by Fe and Al oxides and kaolinite) and from the soils developed from volcanic ash (Andisols dominated by allophane, imogolite, and humus-Al complexes) that are widely spread over the world.

我们常在温带地区发现的2：1型粘土矿物为主的土壤，也出现在热带和亚热带地区。这些土壤不同于世界范围内广泛分布的典型的热带红壤(以铁铝氧化物和高岭石为优势粘土矿物的老成土和氧化土)，也不同于由火山灰（以水铝萤石、伊利缟石和腐殖质-Al复合体为优势粘土矿物的火山灰土）发育的土壤。

The presence of REE tetrad effects in apatites and whole rocks of S-type granites has been reported by Sha and Chappell (1999) and Zhao et al.(1999), respectively. The REE tetrad effect in minerals, such as apatite, spessartite, beryl, alkali feldspar and spodumene, from all zones of Altay No. 3 pegmatite has been found remarkable, and the fractionations among isovalent incompatible elements in these minerals are also significant. This paper puts forward that the REE tetrad effect is one of the basic features of peraluminous melts and the origin of REE tetrad effect might be probably related to some processes prior to the formation of pegmatite magma. The immiscibile liquid separation between silicate melt and hydrosaline melt may be responsible for it.

由于阿尔泰3号伟晶岩脉各带磷灰石以及与其共生的石榴石、绿柱石、碱性长石、锂辉石矿物均存在明显的稀土"四重效应"以及相同电价、相似离子半径的不相容元素间存在显著的分异，并结合最近赵振华等(1999)和Sha and Chappell(1999)报道S型花岗岩全岩和单矿物(磷灰石、独居石、长石、黄玉等)均存在稀土"四重效应"这一现象，本文研究提出，稀土"四重效应"是富挥发分过铝质岩浆体系的一个基本特征，其机制既不可能由含稀土的副矿物早期结晶引起残余熔体相中REE含量变化的结果，也不能定性地归因于流体相与熔体相相互作用过程中稀土元素在流体/熔体之间分异的结果，而很可能与伟晶岩岩浆形成之前某些过程密切相关，S型花岗岩岩浆在液相线以上存在硅酸盐熔体与高盐熔体的不混溶液相分离有可能是过铝质岩浆体系产生稀土"四重效应"的主要原因。

Each starch reagent has its own mode of action on mineral surface, such as primary starch mainly by hydrogen bond, cationic starch by the co-action of hydrogen bond and electrostatic force (for minerals with negative charge on its surface), while carboxymethyl starch, hydroxamic acid starch and dialdehyde starch principally by chemical force accompanied with hydrogen bond and electrostatic force in part. Such chemical forces ensure the close adsorption of reagent on diaspore surface and enforces the hydrophilic of mineral surface. Also the branched chain enable the starch to cover the collector adsorbed on mineral surface, so as to depress diaspore furthermore.

不同淀粉药剂在矿物表面表现不同作用，原淀粉主要是氢键的作用，阳离子淀粉是氢键和静电力的共同作用，羧甲基淀粉、羟肟酸淀粉和双醛淀粉离子性药剂与矿物间的作用除了氢键、静电力外，更重要的是与矿物表面金属离子间产生的化学作用，使药剂能牢固地吸附在一水硬铝石矿物表面，增加矿物表面的亲水性，同时，淀粉支链结构的存在，使它能够掩盖吸附的捕收剂，达到抑制一水硬铝石的目的。
