Crystallized sulfuric salt of SAM was obtained by centrifuging the precipitant at 3000 rpm after adding six times the volume of absolute methanol to the decolorant liquid with a final step of freezing evaporation.

确定了分离纯化SAM的最优条件是：在pH值5.0时，含SAM浓度为3.0 g/L的上柱液，以6 L/h的流速，过装填D152树脂的离子交换柱(φ50 mm×1500 mm)后以去离子水和醋酸洗脱除杂，再用9 L到15 L浓度为50 mmol/L的硫酸以6 L/h的流速洗脱，可以分离得到纯度较高的SAM粗品。

The photolysis decoloration rate increases with the concentration of H2O2, but, with a high concentration of H2O2, the improvement is not obvious.

染料光解脱色速率随H2O2浓度的增加而增加，但在高H2O2浓度时，降解速率增加不明显。

Aiming at the questions such as low grinding concentration,thick fineness of iron ore concentrate and high grade of tailing caused by the wet pre-selecting process before grinding,through the check of the flow and the results of small-scale test,puts forward the improved measures such as increasing grinding concentration,adding demagnetizer,screening the undersize first then floating,etc.

针对磨前湿式预选工艺造成的磨矿浓度降低、铁精矿粒度变粗、尾矿品位偏高等问题，通过流程考查和小型试验研究，提出了提高磨矿浓度、加设脱磁器、对筛下物料进行先筛分后浮选等改进措施。

Methods:Primarily cultured HUVSMC(Passage 3~5)were cultured with the normal and high glucose DEME,and then subjected to control or Fe2+ incubation at various concentrations(0.006 25 g/L,0.012 5 g/L,0.025 g/L,0.05 g/L,0.1 g/L).

以相同浓度接种普通培养液及高浓度葡萄糖培养液培养的3~5代HUVSMC为正常组及高糖组，分别以不同浓度Fe2+处理？

Values of hydration number of amino acids have been calculated at different temperature and concentration of denaturant. It is found that they decrease with increasing temperature and concentration of denaturant. Denaturant and increasing temperature have cooperative dehydration effect on amino acids.

计算了不同温度和变性剂浓度下氨基酸在乙酸钠、丁酸钠、己酸钠、辛酸钠和盐酸胍水溶液中的理论水化数，发现它们随变性剂浓度的增加和温度的升高而减小，说明变性剂和升温对氨基酸有协同脱水作用。

It also resumptively explains the characteristics of DZM-01digital densimeter and the density assay standard for brine extraction and transportation management.
