查询词典 vanadium trioxide

Coal combusts in high-temperature flow of oxygen, and various forms of sulfur in the samples are generated into sulfur dioxide and a small amount of sulfur trioxide; when the infrared detector converts gas concentration to voltage signal, we can detect.

煤样在高温的氧气流中充分燃烧，试样中各种形态的硫分解出来生成二氧化硫和少量三氧化硫，由红外检测器将气体浓度转换成电压信号进行检测。

Ceramics: kaoline, silicone trioxide, clay and so on.

陶瓷：高岭土、三氧化硅、粘土等。

Results: HL-60 cells＇ growth was obviously inhibited after induction with different density arsenic trioxide; autophagy vesica was observed using fluorescent microscope; Bcl-2 gene expression was inhibited; cells autophagy level was negative correlated with Bcl-2 gene expression.

结果：经不同浓度As2O3作用后，HepG-2细胞生长明显受到抑制；荧光显微镜可观察到自噬囊泡的出现；Bcl-2基因表达降低；经相关性分析，HL-60细胞自噬水平与Bcl-2基因表达呈负相关。

Therefore, the indirect pathway, involving an active intermediate nitrogen trioxide, is the main pathway of NDMA formation.

这一结论和NDMA的形成速率与亚硝酸的浓度的平方成正比的实验结果相一致。

One was that one molecule of nitrous acid di-rectly reacted with DMA,and the other was that two molecules of nitrous acid reacted first to yield nitrogen trioxide,which then reacted with DMA.

计算结果表明，DMA与亚硝酸间接反应的活化能比直接反应的低约55kJ/mol，由此可推断DMA与亚硝酸生成NDMA的反应是以两分子的亚硝酸先生成ONNO2再亚硝化DMA为主要反应途径。

A PVC/PNBR TPE was prepared based on PVC and powdered NBR using magnesium hydroxide as flame retardant,and the influence of the flame-retardant synergists,such as diantimony trioxide(Sb_2O_3),zinc borate,ammonium heptomolybdate,zinc oxide and manganese dioxide(MnO_2) on the properties of above TPE was investigated.
