酸处理

Improving the quality of the gulonic acid which is a intermediate of vitamin c , is important to the inter-quality of vitamin c.

古龙酸作为维生素C生产中的重要中间体，其质量的提高，对于维生素C的内在质量(包括晶型的完整、均一、保质期的延长等)有着至关重要的作用，本论文考察了以絮凝法对发酵液进行预处理，效果较好。

The main contents of experiment as following:(1) Modified polymerized ferric sulphate decoloring agent is made through oxidation, hydrolyzation, polymerization with ferrous sulphate heptahydrate, sulphate acid, natrium chlorate etc.

本论文为印染废水的絮凝沉降处理方法提供了一种新型的性能优良的脱色剂，具体内容有：(1)采用七水硫酸亚铁、硫酸、氯酸钠等原料，通过氧化、水解、聚合反应，制备了改性聚合硫酸铁脱色剂。

The solid product was characterized by N2 adsorption-desorption, XRD, TEM and hydrothermal stability test. These results indicated that small amounts of HPMo in the synthesis media could reduce the amount of liquid in-organic acid and crystallization time greatly. And SBA-15 sieves prepared in this method exhibited an excellent hydrothermal stability, as its hexagonally ordered mesostructure was maintained after treated in 100 ℃ water over 72 h.

N2吸附-脱附、XRD、TEM和水热稳定性实验等检测结果表明：用这种方法不仅可以大幅度降低合成SBA-15分子筛所需液体酸的用量和缩短晶化时间，同时反应产物SBA-15在100 ℃的水中处理72 h后仍然保持六方有序的介孔结构。

The effects of extraction time and extracting agent on the determination of hexavalent chromium content in coatings on steel sheets were studied.

钢板在电子行业中广泛应用，传统的电镀和其他表面处理工艺，尤其是铬酸盐钝化，对环境产生巨大影响。

In the pretreatment group, Bak Foong Pill extracts were given for 14 days prior to MPTP. Immunostaining of tyrosine hydroxythase was used to observe the damage of dopamine neurons, and of Bax to detect the protein levels of Bax. High performance liquid chromatography-electrochemical detection was used to investigate the contents of DA and its metabolites dihydroxy-phenylacetic acid and homovanillic in the Str.

给予BFP预处理后，用酪氨酸羟化酶免疫组织化学法观察黑质神经元的变化；同时应用免疫组织化学法检测Bax蛋白表达；应用高效液相-电化学方法检测纹状体巴胺及其代谢产物二羟基苯乙酸和高香草酸的含量变化。

The amounts of bound residues in humin fraction did not change significantly with time from 28 to 224 DDA.

在处理最初28天，富啡酸中〓C-甲磺隆结合态残留物不断增大，随后减少；胡敏素中的结合态残留量在28～224天变化不大。

After pre-treating by the mixed reagent-Hc and one rough flotation( the agent dosage was: sodium silicate 2500g/t, carloxy methyl cellulose 100g/t, hydroximic acid 700g/t, turpentine 20g/t), the concentrate containing 30-31% TiO2 with a recovery of 33-35% can be obtained.

运用混合试剂Hc(用量为47.6kg／t)预处理并经一次粗选(药剂制度为：水玻璃2500g／t，CMC100g／t，羟肟酸700g／t，2~#油20g／t)后，可得到TiO_2品位为30～31％，TiO_2回收率为33～35％的精矿指标。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
