Andalusite is a polymorph with two other minerals, Kyanite and Sillimanite.

红柱石属多晶型物，含蓝晶石和硅线石两种不同矿物。

And 0.64±0.05GPa for sillimanite zone, 750～800℃ and 0.9～1. 0GPa for partial melting migmatites. The results generally show that the kyanite sequence metamorphic belt is a normal medium-pressure sequence.

十字石带有后期向低压转变的趋势；矽线石带的变质条件比中压型正常正常演化条件低，这可能是保留了后期向低压转变的特点。

Within pelitic metamorphic rocks, even though sillimanite is well developed and the low-pressure minerals like andalusite and cordeirite etc.

新疆阿尔泰古生代造山带以低压变质及花岗质岩浆作用广泛发育闻名国内外，泥质变质岩系中矽线石较发育，红柱石和堇青石等低压特征矿物相当常见，但是，石榴石—十字石的组合更普遍。

Citric acid is a good selective depressant in the floatation separation of sillimanite from quartz because it strongly depresses the metal ions activation of quartz and slightly depresses...

柠檬酸对金属离子活化石英有很强抑制作用，而对硅线石抑制作用较弱，是浮选分离硅线石和石英较好的选择性抑制剂。

High-temperature furnace refractories: mainly mullite, corundum, silicon carbide, sillimanite products such as materials, widely used in various electric kiln, furnace (push plate tunnel kiln, shuttle kiln,) and the general coal, oil , gas heat furnace and so on, have a high refractoriness, high temperature strength, thermal shock stability and corrosion resistance, is an ideal high-temperature furnace refractories.

三。高温窑炉耐火材料：主要有莫来石、刚玉、碳化硅、硅线石等材质的制品，广泛应用于各种电窑、电炉和一般煤、油、气高温窑炉等，具有较高的耐火度、高温强度、热震稳定性和耐腐蚀性，是理想的高温窑炉耐火材料。

The Altai Paleozoic orogenic belt of Xinjiang Autonomous Rejoin is geologically wellknown both domestic and abroad by the intensive development of low-pressure metamorphism and granitic magmatism. Within pelitic metamorphic rocks, even though sillimanite is well developed and the low-pressure minerals like andalusite and cordeirite etc. are quite common, the assemblage of garnet and staurolite is more important.

It is the accumulation of a singe stone and wood that makes up the gigantic building.Why don't we be the stone and wood?

巨大的建筑，总是由一木一石叠起来的，我们何妨做做这一木一石呢？

My company's main products haveà°, black slate, rusty panels, paving stone , mosaic, mushroom stone, mosaic panels, slate, culture stone, real stone fountain, tile panels, black tiles panels, rust-watt panels, and other crafts.

我公司的主要产品有青石板、黑石板、锈板，铺路石、马赛克、蘑菇石，拼花板、板岩、文化石、真石喷泉、瓦板、黑瓦板、锈瓦板、工艺品等。

Determine the number of bridging O atoms in the framework of a single sodalite cage.

13.11。确定单个钠沸石笼的骨架中的桥氧原子个数；描述图13.5中的A 型沸石的

It was observed in this pressure range that sodalite underwent a phase transition at about 3 GPa and that the d- 222 value showed an abnormal increase when the pressure was higher than 6.3 GPa. The experimental results are explained on the basis of the pressure effects upon the cage and tunnel structures in sodalite.

对方钠石在高压下相变以及d222增大的原因进行了分析，认为方钠石结构中存在着充填大阳离子的多面体笼和孔道，高压下这些笼和孔道容易扭曲变形，从而造成结构的改变。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
