柱石

Secondly, the mullitization characteristic and thermal expansion properties of this andalusite were studied.

其次，研究了这种红柱石精矿的莫来石化特点及其热膨胀性能。

Temperature and soaking time on mullitization of andalusite were studied by analyzing the XRD data.

研究了烧成温度和保温时间对添加活性氧化铝的红柱石基耐火材料莫来石化行为的影响。

So as a raw material to producte the refractories of high creep resistance, andalusite was very valuable.

因此，红柱石作为生产低蠕变制品的原料有很高的应用价值。

There are abundant mineral resources, andalusite, marble, granite, gold and other mineral resources, greater reserves.

还有丰富的矿产资源，红柱石、大理石、花岗岩、黄金等矿产资源储量较大。

Description of project:There are rich resources of andalusite with the proved reserves of 18 million tons.

三、项目概况：岫岩县红柱石资源丰富，现已探明保有储量1800万吨。

The growth of the porphyroblasts of andalusite and cordierite is of similar process.

红柱石、堇青石变斑晶中也有类似的生长过程。

This andalusite known as the "spar."

这种红柱石称为"空晶石"。

It is deemed that to obtain toughened mullite fibre directly in the sintering course by using high temperature phase change of andalusite is feasible.

认为，利用红柱石的高温相交，在陶瓷烧结过程中直接制取莫来石纤维是可行的。

The results show that when firing temperature increased the amount of mollite increased and residue andalusite decreased linearly.

对试样XRD数据的分析结果表明，烧成温度升高，莫来石含量线性增大，残存红柱石线性减少，二者具有良好的相关性。

5 Ma. These isotopic data provide important evidence for solving the problem of whether there occurred Caledonian mineralization and further support the view that pegmatites and pegmatite rare metal-muscovite deposits in the Altay area were not only formed in the Hercynian.

本次工作通过野外调查和同位素年代学研究，首次在阿尔泰西部的也拉曼大型含绿柱石白云母矿床(426±13Ma)、阿尔泰中部的那森恰大型含绿柱石白云母矿床(447.7±0.4Ma)及阿尔泰东部的青河拜兴白云母伟晶岩脉(436.0±0.5Ma)中获得了可靠的加里东期成矿的同位素年代证据，从而为解决是否存在加里东期成矿的问题提供了重要依据，并进一步认识到阿尔泰地区的伟晶岩及伟晶岩型稀有金属-白云母矿床并非只形成于海西期。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
