For the stationary points along the internal rotation energy surface, full geometry optimization or QST3 transition structure search and fre- quency analysis calculations were also performed.

There are a lot of abstract concepts such as the internal rotation and the normal vibration in the statistical thermodynamics.

Preliminary discussion on selecting rotation direction in 2-D MT inversion;

This paper discusses how to get the rotation directions in the process of computing sine /cosine with CORDIC algorithm and how to apply CORDIC Algorithm in a DDS.

It was analyzed and researched with ANSYS program in this paper that the relation between slanting direction and rotation direction of slanting element of rotor bracket in Jinping first stage hydraulic turbine generator and rational slanting direction of rotor bracket was given.
