Rezumat:
A statistical large-scale study of filaments has revealed the existence of a functional dependence of the length (angular distance between ends of filament, measured on a great
circle on a sphere) of filaments on their inclination to lines of solar latitude.
A cluster analysis method has been applied to the study of filament evolution and a evolutionary classification of filaments is proposed. The results depend on the differential
velocity of filaments.
Different types of evolution sequences were obtained and the evolution of some particular filaments was specially analyzed .
