Bismuth titanate submicron-rods are synthesized by hydrothermal method using anatase and brookite nanocrystallites, respectively, as precursors.

分别以板钛矿和锐钛矿型的TiO2为先驱物水热合成钛酸铋亚微米棒。

The cause for the shift of diffraction peaks is that the amount of Bi intercalated into anatase TiO2 is larger than that into brookite TiO2 under the same conditions.

在同样的条件下，Bi插入锐钛矿TiO2的量多于其插入板钛矿TiO2的量，从而导致部分X射线衍射峰向高角度方向稍微移动。

The results show that the size of M~-TiO2 nanocrystalline particles was quite uniform and the radii were about 15 nm. The M3d-TiO2 nanocrystalline particles were a mixture of brookite and anatase crystal forms.

实验结果表明，M3d-TiO2纳米粒子的颗粒较均匀，粒径约为15 nm，其晶型为锐钛矿和板钛矿的混晶。

He results of TG/DTA and XRD show that Cu2+/TiO2 powder dried at 70℃ is a mixed phase of anatase and brookite. From the TEM photograph, we can find that its dispered property is good and the grains are like balls.

G/DTA和XRD分析的结果表明未经高温处理的Cu2+/TiO2粉体是锐钛矿和板钛矿的混和晶型。

When AgNO_3 concentration was higher than 0.03 M, the prepared samples consisted of anatase, brookite, rutile and metal silver nanocrystal particles, and their grain size ranges were 5-30 nm.

当AgNO_3浓度高于0.03 M时，Ag-TiO_2复合薄膜由锐钛矿、金红石、钣钛矿、金属银颗粒组成，它们的晶粒尺寸范围在5-30 nm。

1The nanocrystalline TiO2 film is prepared by sol-gel and appearance of the film is observed by SEM. The X-ray graph shows the film has lots of anatase and a few rutile TiO2, but does not have brookite TiO2. The average diameter of particle is 25nm according to Scherrer formula.

采用溶胶-凝胶法制备了纳米晶二氧化钛薄膜，通过扫描电镜观察了其形貌，X射线衍射表征显示出制备的薄膜具有大量的锐钛矿晶型和少量的金红石晶型，不含有板钛矿晶型，根据Scherrer公式计算出薄膜的晶粒的平均尺寸为25nm。

Nanosized titania particles consisting of anatase, rutile and brookite phases were synthesized under solvothermal conditions with different alcohols as solvents, hexamethylene tetramine as precipitant as well as precursor of titanium trichloride.

采用不同的醇溶剂，以六亚甲基四胺为沉淀剂，以TiCl3为前驱体，通过溶剂热的方法控制合成出纳米级的锐钛矿型、金红石型和板钛矿型的二氧化钛。

During a special biomineralization process—shell regeneration, we found that both CaLP exhibit special functions in shell related secretory vesicles; during the differentiation of osteoblast MC3T3-E1, CaLP exhibite significant effect on its differentiation and biomineralization.

在对切壳修复这一特殊的生物矿化过程的研究中发现CaLP积极参与了新生贝壳的形成；在前成骨细胞MC3T3-E1向成骨细胞分化的过程中，CaLP能够促进成骨细胞的分化和矿化过程。

Great majority of storeroom of heart of mine of rock of ground collate unit is built at 20 centuries 50, 60 time, build the element outside Yu Ye or hire a house owned by a citizen mostly, be far from base of geological perambulate unit, as a result of year long disrepair, libraries of a lot of sample of rock mine heart are serious damaged, some is close to that collapse, most core box is cankered already...

地勘单位岩矿心库房大多数建于20世纪50—60年代，大多建于野外分队或租用民房，远离地质勘查单位基地，由于年久失修，许多岩矿心样品库严重破损，有的濒临倒塌，大多数岩心箱已腐烂。。。

Study on the background of mineralization system dynamics shows that formation and evolution of the celestite mineralization system are controlled by uplifting of the Qinghai-Tibet plateau and the collision of Gondwanaland and the Eurasia continent, structure stress and thermal-dynamics are the key factors of formation and evolution of the celestite mineralization system.

对该区成矿系统动力学背景研究表明，印度板块与欧亚板块碰撞及青藏高原的隆升控制着锶矿成矿系统的形成和演化；构造应力与热动力是盆地锶矿成矿系统形成演化的关键因素，而构造应力是盆地内一系列热水活动的主要动力来源。

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。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
