Preliminary analysis on the complexity of oil economics;

Discussion on the complexity of petroleum system and its study methodology;

Study of eco-environment on the loess plateau based on complexity theory;

These case examples include: Reservoir characterization and productivity evaluation by using NMR logging, determination of reservoir porosity in complex lithology, identification of oil, water and gas zones under complex reservoir conditions where resistivity log data give poor indication, guiding the.

The kinetic mechanism of the rock with acid and the fracturing methods of complex lithology,on which people have little knowledge,have much different from common carbonate formations.

Based on complex lithology reservoir eveluations and combined with reservoir structure and geology characteristics,analyzed are log responses in the abnormal compressional belts,and hense the purposeful or corresponding log interpretations are made.

Strategy for Surgical Treatment of Complex Injury of Lower Cervical Spine;

Under complex field of vision education research;

Each blast hole should be measured before the blasting to decide the explosive amount and springing times in the condition of complex rocks in slope area.

The complicacy of first symptoms lies in the non-specific.

These factors are analyzed such as similarity property,complicacy that it causes with variability in modeling and expectation degree of designer and so on.

In the new algorithm,storage model of queue structure is adopted to output stack sequence instead of traditional model of stack structure,which could efficiently improve the complicacy of time and space.
