英文摘要

A photometric survey of near-Earth asteroids (NEAs) was conducted from 2012 through 2014 at Lulin Observatory, Taiwan. The measurements of the color indices, B-V, V-R, and V-I allow the classification of 92 NEAs into seven taxonomic types. Of these samples, 39 of them are new classifications. The fractional abundances of these taxonomic complexes are: A similar to 3%, C similar to 6.5%, D similar to 8%, Q similar to 26%, S similar to 37%, V similar to 6.5%, and X similar to 13%. This result is similar to that of Thomas et al. (2011) even though the populations of the D- and X-complex with low albedos are under-represented. The ratio of the C-cluster to the total population of S + C clusters are 0.22 +/- 0.06 for H <= 17.0 and 0.31 +/- 0.06 for H > 17.0, indicating a slightly higher fraction of dark-object population with sizes smaller than 1 Ian.
