金红石

These zircons have nearly the same ~(204)Pb -corrected ~(207)Pb/~(206)Pb ages, with weighted mean age of ca 2.5Ga, interpreted as forming or anatexis age of protolith of the rutile ores.

这两期锆石的~(204)Pb校正的~(207)Pb／~(206)Pb年龄值几乎一致，加权平均值位于2.5Ga左右，可解释为金红石矿石的原岩形成年龄或者深熔年龄。

This sapphire is well-known because of its mineral rutile and the asterism, which is caused by the reflection of incoming light on a three-fold mineral pattern in the stone.

这蓝宝石是众所周知的，因为它的矿物金红石和星群，这是造成的入射光进行为期3倍的反思，石矿物模式。

The mineral inclusions mainly include rutile, zircon, apatite, biotite, spinel and so on.

其矿物包裹体有金红石、锆石、磷灰石、云母以及尖晶石等。

The bond length, density of states and population of TiO2 with oxygen vacancy and titanium vacancy have also been analyzed in this paper.

本文还计算了金红石相TiO2在具有氧空位和钛空位点缺陷情况下的键长变化、态密度和电荷布居状况。

In this paper, we realized a new synthesis method which synthesized nickel boride and boron nitride.

而且经过溶剂热合成与高温煅烧两步法，成功地制备了金红石型二氧化钛(TiO_2)纳米棒，这是一种新的合成纳米TiO_2的方法。

The titanium dioxide is one kind of important industrial chemicals, mainly has the brookite, Rutile and anatase three crystal seeds.

二氧化钛是一种重要的化工原料，主要有板钛矿、金红石和锐钛矿三种晶型。

Raman spectra showed that the structure of rutile including a spot of brookite were obtained.

Raman光谱测量显示，TiO2薄膜主要是金红石结构。

Its crystal type have anatase, brookite and rutile.

晶型有锐钛矿型、板钛矿型和金红石型。

However, silver ions not only promoted the formation of brookite phase but also reduced the phase transformation temperature of anatase to rutile.

同时，Ag+离子的掺杂不仅促进了钣钛矿的形成，并且降低了锐钛矿向金红石相的转变温度。

It is found that anatase is easier to form at acidic condition, but rutile and brookite at basic condition, using methanol as solvent.

结果发现，以甲醇为溶剂，酸性条件有利于生成锐钛矿相，碱性条件有利于生成金红石相和板钛矿相。

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。
