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。

The reasons of the capacity attenuation have primarily to accompany with the Li~+ ion embedding material on discharge process the effect of Jahn-Teller of the occurrence, the deliquescence of the cathode manganese in the material and the decomposition of the electrolyte.

在锂离子电池众多的正极材料中，尖晶石型LiMn_2O_4化合物，由于其原材料资源丰富，价格低，环境污染小，合成工艺简单，成为最有希望取代LiCoO_2的材料，但LiMn_2O_4存在容量衰减大，循环寿命短等问题，阻碍了其商品化应用；容量衰减的原因主要有在放电过程中伴随着Li~+离子嵌入发生的Jahn-Teller效应，正极材(来源：AacBCbd论4b文网www.abclunwen.com)料中的锰的溶解和电解液的分解。

Salt lake is not only very important natural resources. More important is that multi-salts of mineral resources that salt lake have. The mineral resources development have deep impact on sustainable development about lithium、Magnesium、Boron salt and Sylvite, as well on the sustainable development about economy in west of china.

盐湖是不仅是一种重要的自然资源，更重要的是蕴藏着丰富的盐类矿产资源，盐湖矿产资源的开发对钾、镁、硼、锂矿产资源的可持续发展具有深刻的影响，同时也关系到我国西部经济的可持续发展。

Under the instruction of above-mentioned theoretical results, in the thesis chapter 10, the strongly electron-withdrawing anion, C_5O_5~(2-)[dianion of croconic acid (4,5-dihydroxycyclopent-4- ene-1,2,3-trione)], was chosen as the chelator to coordinate with boron to form lithium salt, which will yield high ionic conductivity solutions, and exhibit wide electrochemical stability windows and high thermal stability. As described in the chapter, two new lithium salts containing C_5O_5~(2-), lithium bisborate and its novel derivative, lithium borate for Li-ion battery electrolytes were synthesized.

在上述理论结果的指导下，论文第十章选择了克酮酸二价阴离子——具有很强的酸性、较好的芳香性、较大的电荷分散性、形成的配合阴离子具有较显著的共轭性——作为配体与B配位，合成了二种新的锂盐，通过实验测定了它们的结构和在有机溶剂中的溶解性。

Thirdly,in the view of some different results between the reaction of complexes(2)、(3)and[(Me_3Si)_2N]_3LnLi_3 with aromatic aldehydes, the reaction of 2 equiv of aromatic aldehydes with 1 equiv of lithium amide(1) catalyzed by the YCl_3 was subsequently studied,and better yields of the corresponding amides and alcohols can be isolated.These results indicated that the enolate ligand in complexes(2)、(3)may have impact on the Cannizzaro disproportionation reaction.

第三，鉴于上述配合物2、3和[(Me_3Si_2)2_N]_3LnLi_3与芳香醛反应结果上的一些差别，我们又以三氯化钇为催化剂，将两当量的芳香醛与一当量化合物1的锂盐直接进行反应，结果以较好的产率得到了相应的酰胺和醇，这说明配合物2、3中所含的乙烯醇基可能对此Cannizzaro-型歧化反应存在一定的影响。

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。
