摘要CCD photometric observations of the two near-Earth asteroids (NEAs) 2001 YB5 and 2001 TX16 were carried out in 2002 January with the 0.6/0.9 m Schmidt telescope of the National Astronomical Observatories of China ( NAOC). Analysis of the light curves of these two objects reveals rotation periods of 3.20 +/- 0.03 hr with amplitude 0.21 +/- 0.02 mag for 2001 YB5 and 4.8005 +/- 0.0003 hr with amplitude 0.51 +/- 0.01 mag for 2001 TX16. Spectroscopic observations of the two NEAs were made with the NAOC 2.16 m telescope, ranging from 5000 to 9000 Angstrom. The reflectance spectrum of 2001 YB5 is a little bluish, with a possible weak absorption band from 8000 to 9000 Angstrom, which is consistent with the spectra of B-type asteroids. That of 2001 TX16 is spectrally flat, with a shallow absorption band centered near 7000 Angstrom, consistent with the spectra of Ch-type asteroids.
