 note = {A hypothetical cometary activity of asteroid 2003EH1, which is assumed as a potential candidate for the parent body of the Quadrantid meteor stream, has been examined. Referring to the numerical simulation for dynamical evolution of grains released from 2003EH1, a relation between a radius of survived meteor s (mm) and its lifetime t (yrs) is derived, i.e. log t = 0.23 log s + 7.34. Since there is no information of the past cometary activities of 2003EH1, three models are assumed, i.e. 1) intermittent activity (every 200 years), 2) ordinary continuous activity at every perihelion passage in some interval of the past, and 3) a single split of an asteroid in the past. The size distribution of survived meteors have been determined in each of cases as a form of s(sub -alpha) ds. Finally, it is proposed to search for the dust trail along the orbit of the Quadrantid, as well as a detection of its color. These data will provide a useful tool to confirm the size distribution of survived meteors, and consequently these results would reply on the question how 2003EH1 has supplied the meteors forming the current Quadrantid meteor stream., 資料番号: AA0047898058},
