Development of the over-pressure system is caused by disequilibrium compaction and thermal evolution that are intimately related to the structural styles of the basin.

Loading during burial can produce considerable overpressure due to disequilibrium compaction,particularly during the rapid subsidence of low-permeability sediments.

In the Baimiao area the overpressure mechanism was studied by every aspect of possibility,such as the compaction disequilibrium and hydrocarbon generation.

Overpressure mechanism is researched from the aspects of compaction disequilibrium, hydrocarbon generation and rock salt sealing according to the geophysical and geochemical data.

The balanced realization truncation is adopted to deduce the internal balanced model,and then to obtain the reduced model based on internal balance transform for quadratic characteristic indexes function is obtained.

The balanced realization truncation was adopted to obtain the internal balanced model firstly,and then removed state variables witch were less contribution to structure dynamic response to obtain the reduced model with controllability/observability and quadratic characteristic indexes of internal balanced system separately.

The variation of average voltage,inconsistency rates and capacity for VRLA batteries used in electric bicycles were investigated by means of cyclic tests at 85 % depth of discharge(DoD)and complete discharge.

The imbalance of pattern directly affects the precision of classifier.

Since the reform and opening-up policy being implemented,there appear obvious characteristics of the times in the re-search of social security in china academic circles,such as being initiated later than other countries,imbalance in research con-tents,relative inferiority in quality,self-containment and partiality in outwards-oriented studies,and popularity and rapidity in its development,etc.
