Panzhihua v-bearing titanomagnetite has a titanium recovery of only 7% when smelted by traditional process,an enormous waste of titanium resource.

攀枝花钒钛磁铁矿使用传统工艺流程冶炼，钛资源的回收只有7%，浪费巨大。

The study on the magnetics mechanism of titanomagnetite indicates that the magnetic parameters of the titanomagnetite have the most direct and closest relationship with its particle size, ie. each magnetic parameter increased slowly with particle size decreased, then the magnetic parameters have mutated when the particle size decreased to 0.045mm.

钛磁铁矿磁学机理研究表明，钛磁铁矿磁性参数与粒度有最直接最密切的关系，即随着粒度变细，各磁性参数先是缓慢增大，当粒度降至0.045mm时，产生突变。

The ore sample tested was the tail of Pan-Zhi-Huan vanadic titanomagnetite after magneticseparation and froth flotation of the sulfides,with particle size minus 0.315mm and TiO_2 content 17.5-18%. A high-grade concentrate of 47.7% TiO_2 with a 67% recovery was abtained in a open circuit flotation (one roughing and two cleaning operation), using solely sulfuric acid as pH regulator.

对浮选攀枝花钒钛磁铁矿的磁选—浮硫化物后的尾矿—即试料(粒度为—0.315毫米、含TiO_2为17.5—18%)，除用硫酸调整pH外，在不需添加其他调整剂的情况下，经一次粗选二次精选就可获得含TiO_247.7%、收率为67%的高品位钛精矿。

A method of increasing the lifetime of a hydro-oxidation catalyst comprising, preferably, gold, silver, or mixtures thereof, and optionally one or more promoters, on a titanium-containing support, such as a titanosilicate or titanium dispersed on silica.

一种延长加氢-氧化催化剂寿命期的方法，该催化剂在比如硅钛酸盐或分散在氧化硅上的钛的上面优选含有金、银或它们的混合物，以及任选的一种或几种促进剂。

Therefore, the goal ofour work is to synthesize new microporous titanosilicates. A new titanosilicate with a high Si/Al molar ratio (named JLU-3, JilinUniversity No.3), has been synthesized hydrothermally by using Triethylamine astemplate in the SiO2-NaOH-TiO2 system.

鉴于含钛硅微孔材料多具有优良的氧化催化性能，其合成和性能研究一直为国际上的热点，我们把新型钛硅微孔材料开发作为研究方向。

In this paper, strontium lead titanate was prepared from strontium lead titanyl oxalate tetrohydrate by chemical coprecipitation .

This paper described the preparation of nanometer TiO_2 by means of direct precipitation and homogeneous precipitation with titanyl sulfate,which is a semifinished product during the production of TiO_2 using sulfuric method as raw material.

我国二氧化钛(TiO2，俗称钛白)工业自1956年生产搪瓷和电焊条开始，距今已有近50年的发展历史。近10来，我国TiO2工业发展很快，取得了令人瞩目的成就，其中硫酸法TiO2的生产与国外先进技术相差无异，总生产能力已跃居世界第二位，仅次于美国[1]。

The barium-strontium titanyl oxalate precursor powder was prepared successfully by using the simple oxalate chemical coprecipitation method. The pyrolysis of BSTO at 905℃ in air produced barium-strontium titanate powder. BST powder was characterized with SEM, TEM, XRD and FT-IR, which revealed that the powder was spherical, highly pure, perovskite, and the average particle diameter was 36nm.

采用草酸盐化学共沉淀法制备了草酸氧钛锶钡前驱体，通过905℃高温煅烧，制得了高纯纳米钛酸锶钡，并利用SEM、TEM、FT-IR和XRD对其进行了表征；并将该粉体应用于水中重金属镉离子的吸附。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
