查询词典 titanium oxide

In the ultra high vacuum activation, reduction of the vanadium oxide started at a lower temperature (250℃ to 300℃), and the reduction of the titanium oxides started at a higher temperature(300℃).

当吸气剂置于高真空激活时，钒的氧化物在较低的温度(250℃~300℃)开始被还原，钦的氧化物在稍高于钒的温度(300℃)也开始被还原，400℃时表面已经有大量的金属钦的存在，而Zr的氧化物在(100℃~400℃)激活过程中，则没有明显的变化。

Toxic effect of exposure to VTM dust was lower than that to vanadium oxide and silica, but higher than that to titanium dioxide, which had slight toxic effect.

钒钛尘对肺泡巨噬细胞的毒性作用低于V2O5和SiO2，但高于TiO2.TiO2对肺泡巨噬细胞亦有轻微的毒性作用。

The catalyst contains the 1wt%-20wt% organic auxiliary agent, using the aluminum oxide modified by titanium and silicon as carrier, and using the metals in the VIB and VIII as active metal componemt.

该催化剂是以经钛和硅改性的氧化铝为载体，以第VIB族和第VIII族金属为活性金属组分，催化剂中还含有1wt％～20wt％的有机助剂。

It is discovered that the oxide thickness increases as the starting titanium iso-propoxide increases while other parameters are kept exactly unchanged, and accordingly, the peak redshifts initially and then blueshifts; Moreover, as the mass of silver nitrate increases, the peak redshifts and the absorption band goes wider; the synthetic temperature exerts no effect on the final shape and size of the prepared nanoparticles, only tolengthen the needed reaction time.

结果表明：二氧化钛壳层的厚度随异丙醇钛量的增加而不断增加，其紫外一可见吸收峰先红移，然后蓝移；随着硝酸银的质量的增加，银核的直径增加，并可观察紫外一可见吸收峰的红移，峰宽也逐渐变宽；合成温度的变化对包覆纳米颗粒的大小及形状没有明显的影响，只是改变了合成所需要的时间。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
