The function of high quality anode in the process of aluminium electroanalysis is introduced and the influence of every ingredient of modified pitch on itself and the anode quality is expatiated.

文章介绍了优质阳极对铝电解生产的积极作用，阐述了改质沥青各组分含量对其性质的影响，以及对阳极质量的影响。

It has been well established that metals present in trace amount in raw materials have great influence not only on the anode quality but also on the performance of anodes in the electrolytic cell and on the quality of aluminum liquids.

测定了抚顺铝厂所用的4种炭电极原材料中铁、钙和镍的含量，结果表明，仅从铁、钙、镍三种微量元素含量的角度来选择原材料，辽阳3号延迟焦和改质沥青在提高产出铝的质量，降低阳极消耗方面来说是较好的选择。

Initially the Sales manager reports to HCE management, currently president of Elster Hauck and works in cooperation with Elster BUGU Asia.

具有燃烧应用方面的实际经验，尤其是沥青加热拌和与低温滚筒式干燥的实际经验；·机械或电气工程教育背景。

It is suggested that the emulsify is formed when the oil on the water is stretched and stacked repeatedly by the wave, during which the water is mixed with the oil and entrain into the oil; particle asphaltene forms machinery protection film between oil and water, which stabilizes the water in the oil; the asphaltene film is formed through the accumulation when the water cohere; the resin of high viscosity can intensify the film.

通过对文献资料数据和不同观点进行分析及油水运动特点的实验观察，对溢油乳化物形成机制提出新的见解认为：乳化物是原油在波浪作用下反复拉伸和堆积中发生油水混合、水被夹带入油中而形成；颗粒态沥青质在水滴外形成机械保护膜将其稳定，它是水滴凝聚受阻时在油水界面积累而成，胶质的高粘性强化保护膜起到辅助作用。

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。

It is some uncertain chlorinated compounds not pentachloro ethane and/or hexachloro ethane however that can be detected in most EOM from sedimentary rocks, indicating that the interaction of copper with chloroform can be restrained by EOM and/or they may be transformed into other chlorinated compounds.

铜对氯仿的催化会影响氯仿沥青的定量和组成。
