After thermal treatment, the samples deposited with 12～34％of oxygen concentration become polycrystalline thin films with a single phase of tetragonal structure.

热处理后氧含量12～34％的样品转变为金红石结构的多晶薄膜，氧含量6％的薄膜中存在SnO相。

The degradation rates of benzene and toluene are faster in low concentration than in high concentration.

在锐钛矿催化剂中掺入一定量的金红石可提高催化剂的光催化活性。

This study focus on the structural hydroxyl concentrations of rutile in eclogites from main-hole of the Chinese Continental Scientific drilling project and its areas nearby employing microscope Fourier infrared spectroscopy with unpolarized light.

本文采用傅立叶变换红外光谱研究了中国大陆科学钻探主孔岩芯及其周围地表榴辉岩中副矿物—金红石中的结构水。

The main products are ilmenite, zircon, rutile, xenotime, zircon used for glass screen of color picture tube, and zircon powder used for ceramics and foundry, etc.

主要业务是从事稀有金属海滨砂矿采、选、深加工、行业技术开发和国际贸易等，主要产品有钛铁矿、锆英石矿、金红石矿、独居石矿、磷钇矿、彩色显像管玻屏用锆英石粉、陶瓷和铸造用系列锆英石粉、低熔点玻璃用锆英石粉和高白度、高纯度超细锆英石粉等。

There exists isomorphous replacement in the rutile structure, and the most prominent feature is the average content of oxides, being 1.22%, 0.39%, 0.35% and 0.22% for V 2O 5, Fe 2O 3, ZnO and CuO respectively. They substitute Ti 4+ in octahedra. The valence of V is 5, and its polyhedron is trigonal bipyramid, which causes the lattice distortion, breaks the raw octahedron symmetry into square bipyramid, and produces the microstrains in the structure.

天然含钒金红石平均含V2O5可达1.22％，Fe2O30.39％，ZnO0.35％，CuO0.22％，这些金属离子可替代八面体中Ti^4 。V以5价形式存在，配位多面体呈三方双锥，其在晶格内部对Ti的替代导致晶格畸变，打破了配位多面体原有的八面体对称而呈四方双锥的几何形态，并产生结构微应力。

TiO2 was in the form of magnesium aluminum titanate, Zr/Ti solid solution and rutile in the calefactive process.

在升温过程中，TiO_2表现为镁铝钛酸盐、锆钛固溶体和金红石相。

Indeed, the Grand Canal was constructed partly utilizing the pre-existing channels connecting these lowland swamps and lakes (3) Several rivers have produced deltaic forms on the western side of the lakes;(4) A series of artificial islands have been constructed upon the natural bars or barriers located in the lakes and wetlands, and are locally termed Duo, Dun or Wei (meaning artificial bars or crossways in Chinese).

钻孔B/M界线之下(4078 m～4530 m)的泛滥平原河湖相沉积物中局部地段富含铁锰鲕粒，其主要矿物组成为蛋白石、铁的氢氧化物(包括纤铁矿、水纤铁矿、针铁矿、水针铁矿，统称褐铁矿)、铁锰氧化物(包括硬锰矿和软锰矿，以硬锰矿为主)及极少量的细小碎屑矿物(钾长石、蚀变黑云母、含铁白云母、锆石、独居石、金红石和含钛磁铁矿)。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
