The outside source applies color is because the tooth surface exists various germs, they secrete many sticky sex materials in the tooth surface, everyday the tea dirt in the food, smoke Zi, and drink aquatic and some mineral qualities and people the mineral quality within saliva adsorb on these sticky sex materials to form germ spot and tartar and make tooth yellow gradually or black.

外源性着色是由于牙齿表面存在着多种细菌，它们在牙齿表面分泌许多黏性物质，日常饮食中的茶垢、烟渍、以及饮用水中的某些矿物质和人们唾液中的矿物质吸附在这些黏性物质上形成菌斑和牙石，逐渐使牙齿变黄或变黑。

研究了胶东地区新发现的辉寨金矿床，依据围岩蚀变分带特征，成矿热液组分、成矿温度、氢氧同位素、Rb—Sr等时线数据等，该矿床为产于黄铁绢英岩中的蚀变岩型金矿床，由此扩大了该区找金前

This product is to retain high-grade amino-silicone soft, smooth feel, based on completely overcome the general amino-silicone to treat fabric to make it extremely hydrophobic and yellowing of the problems so that the fabric to keep water absorption and low yellowing, while is also different from commercially available hydrophilic softener with good solid and washability.

本品在保留高档氨基硅油柔软、滑爽手感的基础上，彻底克服了一般氨基硅油处理织物时使其变得极其疏水且泛黄的问题，使织物保持吸水性和低泛黄，同时还区别于市售亲水柔软剂，有着良好的牢固性和耐洗性

In the condition of keeping F、 K、Na content fixed, To improve slag structure and raise slag melting point and viscosity, MgO content is raised and TiO〓 is added. the main content is as follows:(1) Keeping CaO/SiO〓 fixed, MgO content rises from 10% to 16%, the free running temperature goes up 106℃, the viscosity goe down at bigger than 1425℃, but difference is little; keeping /SiO〓 fixed, MgO content rises from 10% to 16%, the free running temperature rises 87℃, the viscosity rises too; adding TiO〓 to 5%, the free running temperature goes up 98℃, the viscosity rise a little.(2) Powder crystal x ray diffraction and microscopic analysis shows: increasing MgO content, the cuspidine will decreace or even disappear, the monticellite goes up with MgO content rising, keeping /SiO〓 fixed, Akermanite content goes up, for high melting point minerals appear or go up, the free running temperature of the slag bearing F is raised; Adding TiO〓, high melting point mineral—Perovskite forms, it can making other minerals'crystalling fast, it is the reason that TiO〓 raises the free running temperature of the slag bearing F.

2对测定粘度的冷凝渣所进行的X粉晶衍射及显微分析和鉴定表明，增加MgO含量，渣中枪晶石将减少甚至消失，而钙镁橄榄石则随MgO含量增加而增加，在／SiO〓不变时，黄长石含量也有所增加，高熔点矿物的出现和增加，提高了含氟熔渣的熔化性温度；加入TiO〓熔渣中将形成高熔点矿物-钙钛矿，钙钛矿的形成还促使黄长石的结晶，这是TiO〓提高含氟熔渣熔化性温度的根本原因。

Coral reef bleaching, the ecological phenomenon of whitening of reefs, result from the loss of symbiotic zooxanthellae and /or a reduction in photosynthetic pigment concentrations in zooxanthellae residing within the gastrodermal tissues of host animals, and death of coral reef could be caused by serious bleaching.

珊瑚礁白化是由于珊瑚失去体内共生的虫黄藻或者共生的虫黄藻失去体内色素而导致五彩缤纷的珊瑚礁变白的现象，严重的白化可以带来珊瑚礁的死亡。

This article introduced the molecular structure, rheological property of Xanthan gum, and also discussed its application in food industry and life technology.

黄原胶是一种广泛应用在食品、化工等领域的微生物多糖，本论文主要论述了黄原胶的分子结构、流变性质及其在食品工业及生物工程中的应用。

The results indicated that the main composition of the sample is α-AsS, with monoclinic crystal system, and there are some trace elements of Ca, K, Mg, Fe, Al, Pb. The appearance of the sample is block and pillar. when heated to about 273.2℃,α-AsS is translated to β-AsS, the melting point is about 304.4℃, and at about 355.5℃, the sample starts losing weight and decomposing.

结果表明：该雄黄标本主要物相为α雄黄，单斜晶系，含有少量α石英(α-SiO2)和雌黄(As2S3)，及微量Ca、K、Mg、Fe、Al、Pb等元素，表面自然结构为柱状或块状，273.2℃时发生AsS由α型转变为β型的相变，304.4℃时为AsS的熔点，355.5℃时失重分解。
