Based on the analysis on the oil sources and migration pathway of this area, the mineralization modes of the oil sand in the area are derived in this paper. Main conclusions are drawn as follows: a. multiphase tectonic activity resulted in multistage hydrocarbon generation of the source rock; b. threestage tectonic activity and threestage mineralization process formed a great deal of unconformity and fault pathway, thus the crude oil could migrate in a long distance; c. the tectonic activity in Yanshan and Himalayan stages uplifted the edge of the basin and the eroded reservoir outcropped to the surface, the light oil escaped and then the oil sand resource formed; d.

通过对该区油源和运移通道的分析研究，得出该区油砂的成矿模式：①多期的构造活动使烃源岩多期生烃；②三期构造活动、三个阶段的成矿过程，形成了大量的不整合面和断层通道，使原油远距离运移；③燕山期和喜马拉雅期构造活动使盆地边缘抬升，经受剥蚀，油层出露地表，轻质油逸散形成了现今的油砂资源。

Three schemes of dealing with AH wash liq uor of high soda concentration were analyzed and compared. The results show th at when the AH wash liquor of total soda concentration 95.06g/L is transferred d irectly to dilution tank, soda concentration in overflow of the 1st mud washer c ould be lowered by about 6g/L and soda loss in red mud attached liquor could be lo we red by 0.25 kg Na2O per ton of alumina and therefore saving cost of about 549 000 RMB per year; moreover, suspension in AH wash liquor could be re-dissolved in to diluted liquor and it is favor not only to rise pregnant liquor R p andimprove precipitation process, but also to avoid alumina loss cost of about 353?000 RMB per year by the suspension settling into red mud.

分析比较了处理高浓度氢氧化铝洗液的3种方案，结果表明：将全碱浓度为95.06g/L的氢氧化铝洗液直接送到稀释槽，可使赤泥一洗槽溢流浓度降低约6g/L ，每吨氧化铝赤泥附碱损失减小0.25kg氧化钠，每年可节省碱耗费约54.9万元；而且还能将氢氧化铝洗液中的浮游物反溶解进入稀释液，有利于精液 R p(氧化铝与苛性氧化钠的质量比)的提高，同时避免了其进入赤泥而被损失，每年可减少氧化铝损失费约35.3万元。

In this study, the variable region genes of three stem McAb 1A〓-D〓, 2F〓-B〓 and 2E〓-E〓 against metal-bound tetrapeptide were joined into a single chain antibody with a linker respectively.

The results show that a the variation of annual mean runoff of Huayuankou section exist an intrinsic dynamic mechanism, which is the results of joint action of affecting factor of periodicity and non-periodicity, having obvious chaos characteristic; b the correlation dimension of attractor of phase space is 5.09 and saturation inserted dimension is 14. It shows that to establish a mathematical model of the annual mean runoff system of Huayuankou at least requires 6 independent variables and the required saturation inserted dimension for rebuilding phase space is 14; c the steady estimate of Kolmogorov entropy is 0.14, showing the average predictable time of the annual mean runoff variation of Huayuankou is about 7 years and; d using nonlinear deterministic chaos model is more suitable to describe the variation of annual mean runoff of Huayuankou.

结果表明：①花园口年平均径流量变化存在着内在动力学机制，是由周期性和非周期性影响因子共同作用的结果，具有明显的混沌特性；②相空间吸引子的关联维为5.09，饱和嵌入维数为14，这说明要建立花园口年平均径流系统的数学模型，至少需要6个独立变量，重构相空间所需要的饱和嵌入维数为14；③Kolmogorov熵的稳定估计为0.14，说明花园口年平均径流量变化的平均可预报时间大约为7年；④用非线性确定性的混沌模型比完全的随机模型更适于描述黄河花园口年平均径流量的变化。

As for the discussion of this problem, series of theories have been achieved inside and outside, such as Lee's "A Theory of Migration", Fei, C. H. and G.
