摘要：

Two globular cluster X-ray sources are known to display orbital variability. We report the detection of periodic variability in the X-ray light curve of a third case, 4U 1746 - 371 in NGC 6441, using data from the Ginga satellite. If orbital, this periodicity confirms that the source is a typical low-mass X-ray binary.
