This application focuses on the aspects of chemical variation rule of rocks and mineral composition changes of mylonites corresponding to the ductile shearing by the case study in the ductile shear zones in south Tan-Lu fault belt. The results show that there exists evendent variation between deformed and undeformed rocks in ductile shear zones, i.e., the decreasing of SiO2 and alkali elements as well as the large ionic lithophile elements, such as Rb,Sr,Ba. The total REE has the behavoir of increasing during the deformation.

本研究着重选择郯庐断裂带南段广泛出露的中深层次韧性剪切带作为研究对象，系统研究剪切带内外变形条件对岩石化学成分变异规律、研究糜棱岩中变形矿物的化学成分随剪切应变作用的对应关系韧性剪切带内，随着变形程度的增加，韧性剪切带糜棱岩中一些常量元素、微量元素和稀土元素和应变强度之间存在明显的对应关系，主要表现SiO2 和碱金属和大离子亲石元素如Rb，Sr和Ba的亏损以及REE总量增加。

In chapter 5, we demonstrates for the first time that solvating the alkali metal ion in〓 by THF can change the electronic state of 〓 significantly.

在第五章，通过对〓(0＜x＜1)进行固体磁共振研究，我们首次揭示碱金属离子的溶剂化对于〓离子的电子态有显著影响(以间接方式，即通过影响〓之间的键合强度而起作用)：当〓离子与〓离子之间键合较弱时，〓离子处于〓电子基态；而当〓离子与〓离子之间键合较强时，〓离子则处于〓电子基态。

Sherds were collected from Hongzhou Kiln covering 8 periods from Eastern Han to Late Tang Dynasty/the Five Dynastied and their bodies were analysed by NAA. The results show that the elemental contents in different samples are quite distinct, even for those in the same period. It means no single element can be used as "fingerprint" to distinguish the period. The curves of the contents of Na, Rb, Ba and Fe varying with lime are very similar, like "U" shape.

对江西洪州窑从东汉晚期至晚唐五代8期400个瓷胎样品进行了中子活化分析，分析结果显示碱金属元素Na和Rb、碱土金属元素Ba及Fe等作为胎的助熔剂元素随年代的变化趋势相似，都呈现出两头高中间低的U字形变化规律，其中Fe作为呈色元素，其含量的高低与瓷胎颜色的深浅是一致的。

Bond length, total atomic charge, frontier molecualr obital energy, and Mullicken Bonding Population proclaimed that electron transfer ought to be possible from benzene to ammonium to form charge-transfer cpmplexes. The molecular obital coefficience showed that the p-π initeraction must be existed between alkali metal cation and benzene.
