At the same, in view of the complication and great variation of heavy oil sewage quality, a new and high effective treatment process is developed.b. Al kind of contradictions in treating the heavy oil sewage are tried to consider systematically and perspectively, and try to avoid the negative effect brought about by the new process.c. When we analyze the contradictions in treating the heavy oil sewage, we combine the oil removal part, suspending material removal part and SlOa removal part to solve the specific problems by taking one anothers advantages and try to do the test repeatedly under the possible conditions.

广泛借鉴国内外稠油污水处理现有的研究成果和经验，并在此基础上努力发展新的思路，针对稠油污水水质复杂、变化较大的特性，探讨开发高效的净水药剂研究具有简捷、高效、耐冲击特点的新工艺；(2)努力从系统的、全面的角度考察和解决稠油污水处理工艺存在的各种矛盾关系，避免新工艺可能带来的负效应；(3)在分析稠油污水处理工艺中各种矛盾关系时，把除油部分、除悬浮物部分、除硬度部分、除二氧化硅部分有机的结合起来，借助各自的优势解决相应的具体问题。

Oil-based lubricants, creams, baby oil or petroleum jelly should not be used with latex condoms.

Taking the eastern sag of the Liaohe basin where coal, oil and gas resources coexist and the Wangying borefield of the Fuxin basin where coalbed gas was first discovered, researched and developed in China as examples, we systematically discuss the control of volcanism on the lateral and vertical distribution of brown coal, flame coal and gas coal in the third member of the Paleogene Shahejie Formation and on the gas source conditions of each coal region. Both the methane released in the process of regional plutonic metamorphism and the additional methane generated by contact metamorphism are calculated. The physical properties and storage capacity of the coal beds changed greatly due to the formation of blackcoal and highlymetamorphosed crevice coal from igneous intrusion. The sealing capacity of intrusions with various occurrences such as dikes is highlighted.

以煤、油、气共生的辽河盆地东部凹陷和我国首次在矿井中发现、研究、开发煤层气藏的阜新盆地王营井田为例，系统地阐述了火山活动在古近系沙河街组三段对褐煤、长焰煤和气煤在平面及垂向分布的控制，进而导致各赋煤区气源条件的不同；估算了王营井田在区域深成变质过程释放甲烷气的基础上，接触变质作用所形成的附加甲烷量；指出由于岩浆侵入形成了天然焦和高变质裂隙煤，使煤层物理性质及储集能力发生了大的变化；强调了岩墙等不同产状的岩浆侵入岩体对煤层气的封闭作用。

Thus an oil-paper insulation system model is introduced for the return voltage analysis. By testing different aged paper or pressboard, the impact of aging degree to the return voltage may be achieved, and it could be helpful to the aging assessment. Based on the principle of polarization process, the basic theory of return voltage is present.
