摘要	The determination for asteroids' spin parameters is very important for the physical study of asteroids and their evolution. Sometimes, the low amplitude of light curves and kinds of systematic errors in photometric data prevent the determination of the asteroids' spin period. To solve such a problem, we introduced the de-correlation methods developed in searching for exoplanetary transit signal into the asteroid's data reduction in this paper. By applying the principle of Collier Cameron (MNRAS 373:799-810, 2006) and Tamuz et al. (MNRAS 356:1466-1470, 2005)'s, we simulated the systematic effects in photometric data of asteroid, and removed those simulated errors from photometric data. Therefore the S/N of intrinsic signals of three selected asteroids are enhanced significantly. As results, we derived the new spin periods of 18.821 +/- A 0.011 h, 28.202 +/- A +0.071 h for (431) and (521) respectively, and refined the spin period of (524) as 14.172 +/- A 0.016 h.
