The elements with the highest stage lixiviating rate are Ni, Co, Cr, Mn, Cd and Cu, and that with the lowest rate is Fe. The elements with the highest values of cumulative lixiviating rate and cumulative lixiviating intensity are Cr, Mn, Co, Ni and Zn, and that with the lowest ones is Fe.

The ultramafic rocks outcropped at the Altyn region are all harzburgites. Remant grains of primary minerals have melted residual texture and elastic deformation texture under high temperature and pressure. The whole-rock analyses show their low TiO〓 contents (0.01～0.04%), low Al, Ca and high MgO contents and wide Mg〓 range (89.35～95.57). Rare earth patterns have two types, namely tabacco pipe-shped and LREE-shaped, of which the former is often seen. The chondrite-nomalized Yb values of these analyses are all lower than 1. The spinels have low Ti and high Cr content and most spinels have Cr# higher than 60. All of the above characteristics show that the ultramafic rocks in the Altyn fault zone are components of metmorphic peridotites of ophiolite from depleted mantle source and most ophiolites from this zone belong to supra-subduction zone type ophiolite with a few mid-ocean ridge basalt type.

阿尔金露头区的超基性岩全为方辉橄榄岩，残余的新鲜矿物颗粒发育有熔融残余结构和高温高压下塑性变形结构，全岩分析显示样品TiO〓的含量低，为0.01～0.04％，具有低的Al和Ca，MgO含量高，Mg〓为89.35～95.57；稀土配分型式有两种，即烟斗型和LREE亏损型，前者占绝大多数，Yb球粒陨石标准化后的值全都小于1；尖晶石低Ti高Cr，大部分尖晶石的Cr〓大于60，上述特征说明阿尔金超基性岩是蛇绿岩的地幔橄榄岩成员，来自亏损的地幔源区，阿尔金蛇绿岩大多属于俯冲带之上型蛇绿岩，有少量的大洋中脊型蛇绿岩。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
