The results from laboratory research indicated that the max rate of dry leaching is 4%;The rate of wet leaching of vitriol is higher than hydrochloric acid, when the concentration of vitriol is 40%, measuring Ratio of Solid to Liquid of serpentine and vitriol is 4:1.,and joined helper leaching agent: HF (The amount put in is 1.2%-1.5% of the 40% vitriol), the rate of leaching of magnesia could over 98%. After using ammonia to trash extraction, basic magnesium carbonate is acquired by ammonium hydrocarbonate.

They then left the transformation to complete itself, and it would nottake less than ten or twelve days for the sulphuret of iron to be changedto sulphate of iron and the alumina into sulphate of alumina, two equallysoluble substances, the others, flint, burnt coal, and cinders, not beingso.

硫化铁变成硫酸铁和矾土变成硫酸铝的过程至少需要十天到十二天，他们经过上述的安排以后，就让它自己去变化，不再照料了。硫酸铁和硫酸铝都能在水中溶解，可是其他如火石、焦炭、灰渣等是不能在水中溶解的。

The results of the effect on HSV-2 virulence experiment and the sample-canceling experiment showed that the four sulfated oligosaccharides had no virucidal activity to HSV-2 but inhibition activity.

初步探讨了低聚糖硫酸酯的抗病毒作用机制，由不同时间加药实验结果推测四种低聚糖硫酸酯具有类似的作用机制，可能作用于HSV-2与细胞的吸附阶段，不能抑制病毒在细胞内的复制过程；低聚糖硫酸酯的作用对象为病毒；对病毒毒力的影响实验和撤药实验说明四种低聚糖硫酸酯不能杀灭HSV-2，仅起抑制作用。

When the heap of pyrites had been entirely reduced by fire, the result ofthe operation, consisting of sulphate of iron, sulphate of alumina, flint,remains of coal, and cinders was placed in a basinful of water. Theystirred this mixture, let it settle, then decanted it, and obtained a clearliquid containing in solution sulphate of iron and sulphate of alumina, theother matters remaining solid, since they are insoluble.

大堆的黄铁矿石经过加热以后，完全还原了，他们把得到的硫酸铁、硫酸铝、火石、炭渣和灰烬全放在一只盛满了水的盆子里，把这种混合物搅和一阵，接着让它沉淀，然后把水倒出来，得到一种含有硫酸铁溶液和硫酸铝溶液的纯净液体，其他不能溶解的物质，还保持着固体的状态。

The corrosion of concentrated sulfuric acid is related to the temperature and the impurity content. The corrosion rate is raised up when the temperature is higher. If the sulfuric acid has some ion nitrated , the pipe corrosion will raise up, too. The product's color is unusual.

浓硫酸管线的腐蚀还与温度及其杂质含量有关，温度的升高，腐蚀速率明显上升；而产品硫酸中含有的硝酸根离子则加剧了硫酸管线的腐蚀，且导致产品硫酸颜色异常。

In the orthogonal designable experiment ,the analysis results of zirconium source, precipitation , the sulfating agent is 1.54%, 2.27%, 5.11%,respectively. This result show that the influence of sulfating agent to the catalytic activity is the biggest. Under the same density of the sulfuric acid soaks, the effect of sulfuric acid is well compared to ammonium sulfate .The second is the precipitation, but the influence of the zirconia source is the smallest.

正交设计实验中锆源、沉淀剂、硫酸化试剂的极差分析结果分别为1.54%，2.27%，5.11%，此结果说明硫酸化试剂对催化剂的影响最大，其次是沉淀剂，锆源的影响最小，同时表明以Zr(NO3)4·5H2O为锆源、乙胺为沉淀剂、硫酸为硫酸化试剂是催化剂的最佳制备方案。

The paper describes bauxite positive flotation desilication process and the agglomeration mechanism of sulphuric acid and aluminum sulphate.

介绍了铝土矿正浮选脱硅生产工艺流程，阐述了硫酸和硫酸铝的团聚机理，通过工业对比试验，证明了在精矿脱水工艺中应用硫酸比硫酸铝具有更优越的技术经济效果。

By pilot tests,the sulphuric acid shows more techno-economic results than aluminum sulphate aluminum in the dewatering process of concentrate.

介绍了铝土矿正浮选脱硅生产工艺流程，阐述了硫酸和硫酸铝的团聚机理，通过工业对比试验，证明了在精矿脱水工艺中应用硫酸比硫酸铝具有更优越的技术经济效果。

All animals were individually fed with a constant concentration and hay for 8 weeks. Results showed that VB12 production from cobalt in lambs was similar when using cobalt sulphate and cobalt chloride, and was significantly higher (P.05) in cobalt sulphate than in cobalt acetate. However, VB12 production significantly decreased in cobalt oxide treatment compared with other forms of cobalt sources. The relative bioavailability of cobalt sulphate, cobalt chloride, cobalt acetate and cobalt oxide was 100%, 95.66%, 89.50% and 22.56% respectively.

结果表明：1硫酸钴、氯化钴、乙酸钴、氧化钴的相对生物学有效率分别为100%、95.66%、89.50%和22.56%(P.01)；2硫酸钴、氯化钴、乙酸钴和氧化钴组血浆VB12的含量分别为1666.9、1594.5、1493.3和376.1pmol/L，硫酸钴、氯化钴组相近，乙酸钴组稍低，而氧化钴组明显下降，血浆甲基丙二酸含量为2.94、3.01、3.49和3.99μmol/L；同型半胱胺含量为8.91、9.23、9.97和10.78μmol/L，硫酸钴与氯化钴组相近，乙酸钴组稍有增加，而氧化钴组明显升高，3个指标反映了一致的钴营养状况。

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。
