摘要：

The Energetic Gamma-Ray Experiment Telescope (EGRET) on the Compton Gamma Ray Observatory has observed PSR B1706-44 a number of times between 1991 and 1995. From these data, a more detailed picture of the gamma radiation from this source has been developed, showing several characteristics that distinguish this pulsar from others: the light curve is complex, with evidence of three pulses; there is no detectable unpulsed emission; and the energy spectrum changes slope at 1 GeV. No two of the known gamma-ray pulsars have quite the same characteristics; this diversity makes interpretation in terms of theoretical models difficult.
