查询词典 metavanadate

EDTA, sodium dihydrogen phosphate and ammonium metavanadate also presented an inhibitory effect on the activity of the enzyme.

EDTA、磷酸氢二钠和偏钒酸铵对该酶活力也有抑制作用。

Test of electrochemical methods Benzylidene acetone, formaldehyde, compound additive D, ammonium metavanadate solution of acid sulfate tin polarization curves, test ammonium metavanadate on the open circuit potential acid sulfate solution of tin.

用电化学工作站测试分析苄叉丙酮、甲醛、复合添加剂D、偏钒酸铵对酸性硫酸盐镀锡溶液的极化曲线的影响，测试偏钒酸铵对酸性硫酸盐镀锡溶液开路电位的影响。

Benzylidene acetone desorption potential acid sulfate tin plating solution is very close to the ideal desorption potential; Benzylidene acetone, formaldehyde can regulate the desorption potential role and can increase the current density range; Composite additive D can make acid sulfate tin plating solution in the hydrogen produced during the rapid detachment; Ammonium metavanadate can catalyze Sn4+ and restore to Sn2+, and then make solution stability.

苄叉丙酮的脱附电位很接近酸性硫酸盐镀锡溶液的理想脱附电位；甲醛具有调节苄叉丙酮脱附电位的作用，并且能够增大电流密度范围；复合添加剂D能够使酸性硫酸盐镀锡溶液在电镀过程中产生的氢气迅速脱离；偏钒酸铵能够催化Sn4+还原为Sn2+，从而使镀液稳定。

In no alteration of HIF-1αprotein, nitric oxide donors, metavanadate and sodium nitroprusside, significantly abrogated DFO-induced apoptosis.

4一氧化氮(Nitric Oxide， NO)供体——钒酸钠(Sodium Metavanadate， vanadate)和硝普钠(Sodium Nitroprusside， SNP)都能够抑制DFO诱导的白血病细胞凋亡，但对CoCl2诱导的细胞凋亡没有抑制作用。

As the primary factor, alkabinity should condition were acquired. As the primary factor, alkabinity should be below 12g/L; the desulfurization effect is optimum when the ratio of tannic and sodiumm metavanadate was 1.5-2; the high absorption temperature is unfavour for desulfurzation 30~40癈 was proved to be effective through experiments.

并得出碱度是影响其脱硫效率的主要因素，总碱度控制在129几以下比较适宜；拷胶和钒在脱硫过程中只是起催化作用，且得到二者比例满足1.5一2时，脱硫效果最佳；温度对脱硫效率的影响主要是在较高温度下会促进副产物 NaZSZO3的生成，所以脱硫反应器中的温度不能太高，经实验证明一般控制在30一40℃。
