本文介绍了1985年至1989年在意大利特拉莫天文台、意大利都灵天文台和智利拉西拉欧洲南方天文台对12颗小行星进行的光度观测结果。使用G.de Angelis(Planet.太空科学。，41,285-290,1993)，我们得到了85TO和360Carlova的第一个自旋和形状解，并改进了以前对12 Victoria，192 Nausikaa和423 Diotima的测定，其中我们首次测定了恒星周期和自转感。我们核对了其他作者对小行星3 Juno、6 Hebe、20 Massalia、43 Ariadne和52 Europa的测定结果，并建议对115 Thyra的自转和形状参数进行非常粗略的估计。
Abstract We present the results of photometric observations of 12 asteroids, performed from 1985 through 1989 at the Astronomical Observatory of Teramo (Italy), Astronomical Observatory of Turin (Italy), and European Southern Observatory (ESO, La Silla, Chile). Using the EA pole determination method described in G. De Angelis ( Planet. Space Sci. , 41, 285-290, 1993), we have obtained the first spin and shape solution of 85 to and 360 Carlova and an improvement of the previous determinations for 12 Victoria, 192 Nausikaa and 423 Diotima, for which we determined for the first time the sidereal period and the sense of rotation. We have checked the determinations obtained by other authors for the asteroids 3 Juno, 6 Hebe, 20 Massalia, 43 Ariadne, and 52 Europa, and suggested a very rough estimate of the spin and shape parameters of 115 Thyra.
