Based on mechanical calculation model of sheet slope crack, the regions nearby equilibrium bifurcation point and evolutions along equilibrium path were investigated by analyzing the buckling behavior and deformation factors of side slopes .

Nearby region at bifurcation point of rock mass slope is derived;the stability criteria of side slope relating to equilibrium path of post-buckling,equilibrium configuration of bifurcation point and post-buckling are established in the form of general side slope.

In accordance with deformed specifities of all kinds of bedding rock slope,this paper studied the regions nearby equilibrium bifurcation point, limit lengths of slope buckling failure and evolutions along equilibrium path by using modality amplitude equation of equilibrium stability built on post-buckling energy criterion.

Almost all proximity indictors of traditional power system voltage stability treat voltage stability critical point as the saddle node bifurcation point, while the Hopf bifurcation point is paid no attention to.

Voltage instability is analyzed through saddle node bifurcation theory with continuation methods and eigenvalue modal analysis.

Fingerprint Matching Algorithm Based on Bifurcation Ridge Comparability;

Advances of the study of the North Equatorial Current bifurcation and the northern circulation of the South China Sea

The core and delta information is used to classify the fingerprint,and then the bifurcation ridge comparability is used to find reference minutiae according to the comparability of two ridges on which the highly reliable bifurcation lied.
