Experiments of rotor wake distortion in pitching maneuvers;

To improve the prediction of the rotor s off-axis aerodynamic response,the wake distortion effect of maneuvering rotor was studied with the introduction of time-accurate wake curvature parameter(KR) into the maneuvering rotor model.

A general dynamic,distortional wake model based on the nonlinear and unsteady Peters-He inflow model was investigated and applied to the real-time wake model,it was an important part in the forward acceleration flight because the wake distortion effect and the blade unsteady aerodynamics relation to the whole aerodynamic force.

Fission track etching condition of tourmaline;

Fission track dating and thermal history of Habahe rock body in Altai;

Apatite fission-track records of the tectonic uplift of the central segment fo the Kunlun Mountains on the northern margin of the Qinghai-Tibet Plateau;

The fission-track dating method has been widely used to constrain the exhumation of mountains and tectono-thermal evolution of basins.

It reflects progress in understanding the temperature dependence of fission-track annealing and in interpreting the information contained in fission-track length distributions.
