Monopoly capitalism went thought two stage: capitalism of scale monopoly and capitalism of technology monopoly.

The author observes that new changes have occurred in the capitalist industrial organizations since World War II, resulting in the trend of turning from a market system under scale monopoly to a market system under monopoly of technology.

Structural characteristics of deep fault depressions in the southeastern uplift area of the Songliao basin,China and their significance for petroleum exploration;

Characters of reverse tectonics and its forming mechanism in late of fault depression in Songliao basin.;

The fault depressions,isolated with one another but genetically related,are developed in deep of southern Songliao basin and most of them are considered to be capable of generating hydrocarbon.

This paper analyzes the gas reservoir formation condition of all the rifts in the north part of Songliao Basin, and proposes the apparent difference of hydrocarbon source rock development, organic matter evolution and cap rock condition among the rifts.

It determines that Xujiaweizi Rift is a complex rift controlled by two large fractures,i.

This paper discusses the effect of tectonics such as uplifting of the asthenosphere in the deep basin,the interaction between the crust and the mantle,the net structure,crust thinning and the detaching zone on the forming and evolving mechanism of the shallow rift and faults,providing.
