It can draw the conclusion thatδ~(34)S_ in solution has an approximate content(0±3‰)with S isotope of pyrrhoSne by measuring S and Pb isotope of sulfide in ore bodies,a lower value shows S in hydrothermal fluid is origin from magma;Linear array of Pb isotope in galenite suggests that Pb may be multisources.

对矿体硫化物进行硫和铅同位素测定，获得溶液的δ~(34)S_与磁黄铁矿硫同位素组成相近约等于0±3‰，δ~(34)S_值小，表明热液硫是岩浆来源，方铅矿铅同位素线性排列，暗示出铅可能是多来源的。

The occurrence mechanism of gold is discussed on the basis of microtexture and crystallographyThe fact that the fineness of gold in the deposit is low suggests that the development degree of sulfi...

该矿区金的成色较低的事实，说明了硫化物的发育程度直接影响着金的成色。推断石湖金矿是在多期次成矿的晚期才大量富集的。

反应生成由多磷酸盐和铁硫化物组成的反应膜，该膜具有较好的抗磨作用，仲烷基ZDDP比伯烷基ZDDP的抗磨性好，而伯烷基ZDDP的抗磨性优于芳香基ZDDP的。

According to geological characteristics of mineral area,geological conditions of mineralization,geochemical characteristics,material sources of mineralization,mineralization patterns,as well as physical and chemical conditions of mineralization,it summarize the mineralization pattern and genesis of ore deposit of Xianghualing mining areas,considering that mineralization materials in this deposit mainly come from magma,genesis patterns of deposit include high-temperature gas-liquid Nb、Ta deposit related to albitization laying in or on the edge of granite rock bodies,median-high temperature Skarn Sn,Be deposit related to skarnized laying at the inner contact-belt of granite and carbonate rock bodies;median-high temperature cassiterite -sulphide mineral deposit related to skamized laying at outer contact-belt of granite and carbonate rock bodies and median-low temperature hydrothermal liquid Pb-Zn-Ag deposit related to silicification,fluorite, propylitization laying in wall rocks;Series of generalized magma- hydrothermal liquid type Sn-polymatellitic related to magmatic activity in Yanshan period as a whole.

通过对矿区地质特征、成矿地质条件、地球化学特征、成矿物质来源、成矿作用、矿化型式以及成矿物理化学条件的分析，总结了香花岭矿区的矿床成因以及成矿模式，认为香花岭锡多金属矿成矿物质主要来源于岩浆，矿床成因类型包括花岗岩体内及其边部产出的与钠长岩化有关的高温气液型Nb、Ta矿床、花岗岩体与碳酸盐岩内接触带产出的与矽卡岩化有关的中高温矽卡岩型Sn、Be矿床、花岗岩体与碳酸盐岩外接触带产出的与矽卡岩化有关的中高温锡石硫化物矿床以及围岩中产出的与硅化、萤石化、青磐岩化有关的中低温热液型铅锌银矿床，整体构成与燕山期岩浆活动有关的广义岩浆热液型锡多金属成矿系列

Protein in the terms of eggs contains quite much amino acid which after being heated for long time will decompose sulfuret which reacts with the iron in the yolk then form the iron sulfides that is hard to be absorbed by body,thus cause mass loss of nutriments.

蛋品中蛋白质含有较多的蛋氨酸，经过长时间加热后，它会分解出硫化物，它与蛋黄中的铁发生反应，形成人体不易吸收的硫化铁，营养损失较多。

It hold well foreground of sciences and commercial application such as oceanic polymetallic concretion, cobaltic ag1omeration, polymetallic sulfide, natural hydrate and deep-sea hot spring creatures. The abundance resources were called the strategic substituted energy of human sustainable development.

大洋多金属结核、富钴结壳、多金属硫化物、天然气水合物、深海热泉生物等新型资源具有很好的科研与商业应用前景，被誉为21世纪人类可持续发展的战略接替能源。

The main cobaltiferous mineral states are: cobaltiferous ferruginous sulphide, oxide, carbonate, sulphate, clay mineral and silicate.

大横路钴矿床矿石中的钴为多相多态存在，主要的含钴矿物相有含铁的硫化物、氧化物、碳酸盐、硫酸盐、粘土矿物和硅酸盐，其中粘土矿物吸附态的钴约占矿石总钴量的三分之一，这一赋存状态的钴，用通常的选矿方法难以选取，是造成该钴矿床以往钴回收率低的主要原因之一。

On the paper, The Metallogenic laws of massive sulfide deposits and postmagmatic hydrothermal deposits in time and space are sumed up through main copper and polymetal deposits characteristics, ore-control factors, metallogenic chronology, ore-forming tectonics setting and paleographic reconstruction are studied.
