Remarkable changes are ubiquitous for NSO fractions and asphaltene. The yields of fatty acids from copper-treated EOM, in particular palmitic acid and stearic acid, do not decrease for the interaction of copper with organic acids but increase markedly.

加铜得到的可溶有机质脂肪酸的含量不仅没有因为铜和脂肪酸的作用而减少，反而大幅度增加，尤其是氯仿沥青中的脂肪酸，甲醇沥青中的脂肪酸增幅较小。

For copper-treated chloroform extracts the total yield always increases, whereas that of the methanol extracts does not. GC-MS analysis on the fractions from EOM is carried out. No effect on the saturated hydrocarbons is found. For aromatic hydrocarbons copper has no influence on some samples and strong influence on the other.

沥青族组分分析表明，铜的加入对饱和烃在定性和定量两方面基本没有影响；部分样品的芳烃也基本无变化，但另外一些样品的芳烃差别却很大，这些样品加铜后得到的芳烃要比不加铜的在数量上高出几倍。

ConclusionIt is the first time that the petroleum ether extract and ethyl acetate extract of Nervilia foadii Schltr. are proved to be the effective anticancer fractions in vitro.

结论首次确定了青天葵的石油醚和醋酸乙酯部分是体外抗肿瘤作用的有效部位。

Various fractions of tannins with different polarities and relatively narrow molecular weight distribution were obtained by extractions using ether and ethyl acetate sequently.

通过乙醚和乙酸乙酯萃取可得到极性不同的组分。分析表明，各级分的分子量分布范围不同，且相对较窄。

The testing results showed that the optimal reduction conditions are 1320℃ for 120 min and the proportional mass fractions of activated carbon powder and the additive A are 3% and 5%, respectively. The additive A accelerates the aggregation of metallic grains so as to make the enriched metallic grains easier for magnetic separation. The mass fraction of maximum nickel in ferronickel alloy and nickel recovery in the laterite-nickel ore are 8.31% and 95.44%, respectively. Metallic nickel is thus enriched.

研究结果表明，最佳反应条件：还原温度为1320℃，还原时间为120min，还原剂与添加剂的质量分数分别为3%及5%；添加剂可促进金属晶粒的聚集，富集的金属晶粒更易于磁选分离；还原产品镍铁合金中镍的质量分数可达8.31%，矿石中镍的回收率可达95.44%，金属镍得到了富集。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。
