Abstract:
Hunt
firstly presented eleven types of three-system in general and special
cases. The geometrical properties of these types are studied
systematically and The rule of the spatial distribution of the axes of
all the twists under each of the types in principal coordinate system is
illustrated by geometry. It develops Hunt’s classified theory and is
easily for application.
Key words:
