The classical chaos phenomena from low frequency driving octupole deformation;

The alternating parity band structures and strong E 1 transitions between negative and positive parity bands show strong octupole deformation.

The quantized Hamiltonian is derived from the general parametral form of the octupole deformation in the space of parameter, which can be used to analyze all sorts of nuclear octupole vibrations.

Modeling of electrostatic suspension system of ESG with eight electrodes;

In order to study the dynamical property of transverse beam instability,an octupole magnet system was developed in Hefei light source.

Within the O(6) limit of s\|d IBM1,the effective three\|body potential between the interactions of d \|bosons is introduced with the consideration of octupole states,which are produced by a f\| boson plus ( N-1) s\|d \|Then the analytic expressions of negative parity energy spectrum formula is obtained.

Within the O(6) limit of s-d IBM1, the effective three-body potential between the interactions of d-bosons is introduced with the consideration of octupole states, which are produced by a f-boson plus (N-1) s-d-bosons.

Taiji is a dominant branch of Chinese Wushu while TaijiBafa is the essential of Taiji techniques and skills.
