In order to ensure power system operation with safe and reliability, high and low voltage apparatus and conductors should be verified in short-circuit dynamic stability and thermal stability while they are chosen in the design of power system.

This paper discusses the short-circuit verifying of wires in dynamic stability and heat withstand while the wires are chosen in the design of power system.

The reason that dual-breaker configuration had higher dynamic stability was explained as well.

In this paper,if edge-water gas reservoir is of homogeneous isotropy and initial gas-water interface is horizontal,we derived out condition of gas seepage velocity of stable movement for gas-water interface with basic law of Darcy seepage,the same as,proposed conclusion in this paper presented basic for confirming reasonable production of gas well in edge-wa.

The characteristics of stable movement in viscous debris flow after occurrence along transportation sector are emphatially discussed.

In the steady flow in manifolds,there exist a number of stable flow states in the branches for the same main duct flow rate.

Relationship between softening point of SBS modified asphalt and dynamic stability;

In this article,the parameters of Marshall stability,freeze-thaw splitting strength and dynamic stability etc.

The accuracy of the lab rut evaluating indexes was analyzed with 4 hours Hamburger wheel Tracking test,and it was considered the dynamic stability can evaluate wheel tracking test effectively,meanwhile it suggested the dynamic stability index should be adjusted according to the initial deformation of the wheel tracking test.
