Type I is composed of rhyolitic rocks, which are characterized by higher Si and alkali contents and lower Al and Ti contents, Na2O/K2O1 and a weak negative Eu anomaly (δEu=0.65–0.95), enriched in Sr and Ba and poor in Rb. Types I and II probably formed in an extensional to postorogenic extensional environment, accompanied by compressional uplift.

The results show that Sb addition can diminish the crystal grain, but the content of segregative phase at crystal boundary increases, and the current efficiency of material is low. Compared with Sb addition, Sn addition can also diminish the crystal grain, the current efficiency increases, the content of segregative phase at crystal boundary reduces, but diffusional corrosion of the anode surface is not uniform. The cooperation of Sb and Sn can prevent Si from segregating effectively and enhance the current efficiency obviously. At the same time, anode materials have preferable surface dissolution characteristics.

结果表明： Sb具有细化晶粒的作用，但晶界存在较多偏析相，电流效率偏低；与Sb相比较， Sn也具有细化晶粒的作用，电流效率有所提高，晶界偏析相较少，但阳极的表面腐蚀溶解不均匀； Sn和Sb的协同作用在于能有效地抑制Si的偏析，显著提高阳极的电流效率，使得阳极表面具有良好的腐蚀溶解性。

From the fields of regional crust-mantle structure, metallogentic settings, history of tectonic-magmatic activity, distribution of high antimony anomaly, characteristics of deposit, origin of ore-forming materials (including Sb, C, Si, S, solution and associated elements), black dikes, the relation of deposit and mantle metasomatism fluid is expounded by means of geology and geophysics. Xikuangshan antimony deposit is proved to be a typical vein deposit formed by mantle metasomatism fluid. On the basis of this knowledge, the prospecting criteria of blind orebody of the deposit are given as follows: extensive structuer which indicating the activities of mantle metasomatism fluid, change of host rocks (especially exsisting shale barrier bed), silication and carbonization alteration.

文中对地幔交代流体组成、性质、活动特点及其成岩、成矿作用作了综述与探讨；从锡矿山区域壳幔结构和成矿背景、地质构造-岩浆活动史、高锑地球化学场结构分析、矿床特征、成矿物质(包括Sb、C、Si、S、流体及伴生元素)、与成矿有时空联系的暗色脉岩等方面入手，利用地质、地球物理、地球化学手段多方面论述了矿床与地幔交代流体活动的关系，论证了锡矿山超大型锑矿的地幔交代流体成因，并以此为基础提出盲矿体地质找矿标志：即指示地幔交代流体活动的构造，尤其是具有成矿元素和碱质异常、热液蚀变的断裂构造；有利的岩石物理化学性质；硅化、碳酸盐化围岩蚀变等。

The powders all have different proportional elements containing O, F, Al, Si and Ca. They all have amorphous structures and are constituted by near spheroidic nano particles whose size is in the range of 30~70 nm.

各粉体均含有不同比例的O、F、Al、Si、Ca元素，且均为非晶态的近球形纳米颗粒，粒子直径大约在30~70 nm范围。

Structures of seven compounds were elucidated mainly by the use of spectroscopic methods, especially by detailed analyses of 〓 and 〓 NMR spectra with the aid of 2D NMR spectroscopy including 〓 COSY,〓 COSY, HMQC, HMBC, COLOC, and MS techniques including EI-, CI-, SI-, ESI-MS and HR-EI-MS. Stereochemical structures of some of them were also determined on the basis of results of their NOEDS, NOESY and coupling relation.

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。
