Through linear sandpack model and transparent micromodel experiment,this paper studies migration rules of weak gel in porous media and general characteristics of EOR.

Numerical simulation of the dust movement rule in fully-mechanized coal faces;

Numerical simulation analysis of the movement rules of projectile in soil;

The differential equations of three mass points are derived for different mass relations between them,and their analytic solutions are obtained,by which the movement rule of three mass points are discussed.

Exploration potential and migration-accumulation rules of natural gas in Junggar Basin;

The law of motion of underground water in fissured rocks and status quo of the numerica modeling;

The movement parameters and dynamics parameter are discussed starting from the terry mechanism design and the law of motion.

To counter the no continous jerk curve of the general purpose harmonic trapezoidal combinativial law of motion for cam mechanisms, this paper reconstructed the mathematical model of the law of motion on the basis of the continous jerk curve, and remained the advantages of the law of motion.
