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。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
