To Al2 (SO4) 3 and different amounts of urea as raw material, two-block copolymer P - b-P the existence, Microwave prepared by the spherical coral Boehmite, 800 ℃ calcining, Alumina is a powder.

以Al2(SO4)3和不同量的尿素为原料，两亲嵌段共聚物P-b-P的存在，利用微波法制备出珊瑚球状的勃姆石，经800℃煅烧后，得到了氧化铝粉体。

The results show that the predominant minerals in the feed coals are kaolinite and boehmite, averaged 71.1% and 21.1% among the total crystal minerals, respectively.

结果表明，准格尔电厂煤中矿物以高岭石和勃姆石为主，分别占煤中矿物总量的71.1%和21.1%。

The characteristic length of the products was 60 nm and the diameter of them is about 2-5 nm. By the comparative experiments, it could be concluded that the multiporous structure of AAO was the key reason for synthesizing boehmite nanowires by this method.

分析了反应过程及水热反应温度和时间对勃姆石纳米线形貌的影响，并通过对比实验表明AAO模板的纳米多孔结构是水热反应生成勃姆石纳米结构的必要条件和主要原因。

The result shows that a great mass of kaolinite and boehmite in Zhungar coal are turned ioto mullite. There is no boehmite and less kaolinite found in Shenhua coal, so there won't be too much mullite formed.

结果表明，准格尔煤粉中包含的大量高岭石和勃姆石为莫来石的大量生成提供了条件，神华煤中不含勃姆石，高岭石的含量也不多，莫来石的生成量很少。

The high level of Al(subscript 2)O(subscript 3) in the fly ash is yielded during the transformation and decomposition of kaolinite and boehmite in the feed coal at a high temperature, commonly between 950~1200℃ Very low level (1.9%) of quartz in all minerals of the coal has correspondingly elevated the Al2O3:SiO2 ratio of the fly ash up to 1.50, which is three times of common fly ash in China.

粉煤灰中高Al2O3含量来源于煤中丰富的高岭石和勃姆石矿物在电厂高温下的转化和分解产物；石英仅占煤中矿物组分的1.9%，也相应地提高了粉煤灰中的Al2O3/SiO2：质量比，使得这一比值达到1.50，是常见粉煤灰的3倍左右。

Synthesis and Characterization of Boehmite AlOOH Nanotubes;2. The authors found an extremely-enriched boehmite and its associated minerals for the first time in the super-thick No.

运用X射线衍射分析、带能谱仪的扫描电镜和光学显微镜等技术，首次在鄂尔多斯盆地东北缘准格尔矿区6号巨厚煤层中发现了超常富集的勃姆石及其特殊的矿物组合，勃姆石含量可高达13。

The composite membranes with different ratio of Al〓O〓 to SiO〓 are composed of amorphous matter or amorphous matter and γ-Al〓O〓 when sintered at 600℃. The composite membrane with mullite composition go thrsought the following phase transition as the temperature rising from 200℃ to 1100℃: amorphous matter and boehmite (200℃)→amorphous matter and γ-Al〓O〓(4001000℃)→mullite and α-Al〓O〓.

经热处理后不同化学组成的复合陶瓷膜由无定形态或者无定形态和γ-Al〓O〓组成，具有莫来石化学成分的复合膜随着烧结温度的升高，其组成分别为无定形态和勃姆石（200℃）、无定形态和γ-Al〓O〓（400-1000℃），并在1100℃时析出莫来石和α-Al〓O〓。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
