The uncloseness of a spiral electric current is analysed in a very long spiral tube,and the equivalent current in its axis and the magnetic fieid are computed further.

A non-close,non-block and low-overhead checkpointing algorithm is proposed for computational grid service system which provides computation function for mobile agents.

Xiaolinke-Aogula fault spans Qijia-Gulong depression and the west slope,and its sealing ability and evolution history play very important roles in determining whether the oil and gas generated and expelled from Qijia-Gulong depression can migrate to and accumulate in the west slope.

The barrier sealing ability is relative jeven the high displacement pressure barrier only stops free hydrocarbon at a certain level,without obstruction to diffuse hydrocarbon and water solution hydrocarbon.

Fault physical modeling experiment and its application in the assessment of fault sealing of Xinzhuang oilfield,Henan,China;

Evaluation method of grey relationship analysis of fault sealing;

Study on the Capacity of Lateral Sealing of Faults in the Luliang Uplift of Junggar Basin;

Division of seal evolution stages of shale caprocks to gas in each phase and its research significance;

Based on the analysis of formation and evolution of overpressure,the evolution law for sealing of overpressured mudstone caprock was quantitatively studied by the quantitative study of evolution law of overpressure.

When people studied sealing properties of a fault in the past, it was only qualitatively said that the fault is“sealing”or“nonsealing”.

The Closure of an Extensive Subexponential Distribution Class under Convolution Roots;

The PH-closure in Qucueing System with Adaptive Multistage Vacations;

Based on studying fault development and movement characteristic of Da I Member in northern Wuerxun Sag, this paper evaluates the vertical closure of main faults in Da I Member using filler lithology in fault belt and shale plastic deformation strength.
