    The waterbody of lake basin has some properties of its own.Deltas entered into lake basin are commonly belonged in high--constructive ones,since the capa- city of river is always the major controlling factor in their formation.Based on these prerequisites,this paper presumes to categorize lake deltas on the basis of slope and distance between source area and depocenter.There are two end-mem- ber types in lake deltas,i.e.fan-delta and birdfoot-delta.The fan-delta is formed where the slope is steep and the depocenter is closely in the neighbor of source area. In contrast,birdfoot-delta is formed where the slope is gentle and the depocenter is far away from source area.The rest of deltas are the transitional types.Inte- grating some oilfields'instances,this paper describes the main characteristics of va- rious types of delta and points out that they are distinctly different one another, but among them there have gradually evolutionary relationships depended on the evolution of slope and distance from source area to depocenter.Therefore,such categorizing may be of great advantage in the effective prediction of lake deltas during exploration and development.

    湖盆水体条件与海盆很不相同,入湖三角洲一般总是以河流能量占主导地位的高建设相三角洲。本文从这一总的前提出发,提出了以坡降大小和距物源区远近为主要因素,对入湖三角洲进行分类的设想。认为入湖三角洲存在两种端点类型:扇三角洲和鸟足状三角洲。陡坡降和沉积中心紧邻物源区形成扇三角洲;缓坡降和远离物源区形成鸟足状三角洲。其它三角洲都是这二者之间的过渡类型。文中根据油田实例,归纳了各类入湖三角洲的主要特征,认为它们之间既有明显区别,又有从属于坡降和距物源区远近变化的过渡演变关系。因此,这样的分类,有利于在湖盆勘探和开发油田时,对三角洲进行有效的预测。

    The samples of surface layer sediments from 220 stations from the Xiamen Harbour were analyzed for Eh value, ratio of Fe~(3+)/Fe~(2+) and content of organic materials. The results show that the Eh value, ratio of Fe~(3+)/Fe~(2+) in the harbour is higher that in the estuary. On the contrary, the content of organic materials in the estuary is less than that in the harbour. In the survey area, the range of change and average value of Eh, Fe~(3+)/Fe~(2+) and content of organic materials were—213 to 436, 62,9(mV);...

    The samples of surface layer sediments from 220 stations from the Xiamen Harbour were analyzed for Eh value, ratio of Fe~(3+)/Fe~(2+) and content of organic materials. The results show that the Eh value, ratio of Fe~(3+)/Fe~(2+) in the harbour is higher that in the estuary. On the contrary, the content of organic materials in the estuary is less than that in the harbour. In the survey area, the range of change and average value of Eh, Fe~(3+)/Fe~(2+) and content of organic materials were—213 to 436, 62,9(mV); 0.29—14.7, 1.49; ND—3.25, 1.18(%). We have found that hydrodynamic action is a major controlling factor of oxidationreduction sedimentary environment in the survey area. There is a close relationship between the Eh, ratio of Fe~(3+)/Fe~(2+), content of organic materials and sedimentary type. Eh value, ratio of Fe~(3+)/Fe~(2+) in coarse sandy area are higher than that in find sandy and muddy areas. While the content of organic materials in coarse sandy area is less than that in find sandy and muddy areas. Based on the results, the survey area can be groupes into strong oxidation area, weaker oxidation area, weaker reduction area and reduction sedimentary area. The weaker reduction area covers about 160kin~2, equal to 2/3 of the survey area.

    In the emulsion polymerization process whether the problem about the average seed size, the size distribution and the seed amount used will exert any action on the average size as well assize distribution of the final polymer particles formed has beed studied.Considering from the concept in respect to desorption and resorption of the free radicals from the polymers in vinyl chloride emulsification polymerization process, it is be lieved that the major controlling factor on the particle size and its distribution depends most likely upon the magnitude of the total external surface of the seed particles. Experimental results show that either the increase of the average seed size or the decrease of the quantity of the seed used gives no sensible increase of the particle size of the polymer particle formed. Hence, in order to have an appropriate particle size as well as the desired size distribution, seed quantity used should not be decreased and, in general, it should take the amount about 3—5% of the total amount of the monomer used by weight.

    本文研究了氯乙烯种子乳液聚合中种子的用量、平均粒径和粒径分布对聚合物粒子大小及分布的影响。按照氯乙烯乳液聚合中自由基从聚合物粒子的解吸和再吸的概念,提出种子对聚合物粒子大小与分布影响的关键在于种子粒子的总表面积。结果表明,当种子粒径增加和种子用量减少时,聚合物粒径并不随之增加。因此,为了得到适当的粒径和分布的聚合物粒子,种子用量不应减少,通常为单体重量的3—5%。
