4.In this paper, the organic electroluminescent device, configuration, fabrication and illumination mechanism are briefly described Moreover, it reports the situation of organic and inorganic EL device both in Japanese unexamined patents disclosed from 1989 to 1997 and in U S A patents authorized from 1989 to 1996 Furhermore, it lists main companys engaged in the study of organic EL device and its patents in the world, and so, it shows the development tendency of EL device
6.Organic compounds of chlorine such as DDT, for example, can literally be found all over the world due to atmospheric transport, even though many of these substances have long been banned in western industrialized countries, and they often remain and accumulate in parts of both terrestrial and aquatic food chains.
7.The basin-formed mechanism, evolution model and petroliferous geological features of compresso-shear basins in the world are analyzed, by which six aspects of the features are summarized as follows: 1) in the compresso-shear process, the sedimentary speed of basin is high, forming thicker coarse-grained clastic rocks which normally shape good petroleum reservoir; 2) the source rocks of basin tend to coming from the organic matter-enriched rocks formed in pre-compresso-shear stages, except that in intense compresso-shear process, deep water-semi deep water source rocks are possibly developed in pre-compresso-shear stages, e4xcept that in intense compresso-shear process, deep water-semi deep water source rocks are possibly developed in frontal of deep depression (fore deep) of thrust belt; 3) the en echelon folds (including anticline and fault-nose structure) are generally as good oil traps; 4) the compresso-shear process is helpful to hydrocarbon accumulation; 5) it may promote the maturity and hydrocarbon-generating process of organic matte, and 6) the thrust belts in the surrounding areas of compresso-shear basin are favorable are favorable domains for petroleum concentration.
