摘要：

The light curves for three eclipsing binaries in the Magellanic Clouds have been obtained using CCD uV(J)T(C) photometry. One target in the LMC, MACHO*05:36:48.7 - 69:17:00, is an eccentric system, e = 0.20, with a period of 3.-853534 +/- 0.000005 d. Initial solutions indicate a primary component in the range T-eff,T-1 = 20,000 - 35,000 K and the secondary T-eff,T-2 1000 - 2000 K cooler than the primary, with inclinations ranging i = 84.2degrees - 86.0degrees. Two targets in the SMC, MOA J005018.4 - 723855 and MOA J005623.5 - 722123, have periods of 1.8399 +/- 0.0004 and 2.3199 +/- 0.0003 days respectively. Both have circular orbits with the former being a semi-detached system.
