摘要：

As part of an international collaboration to measure the low-frequency spectrum of the cosmic microwave background (CMB) radiation, we have measured its temperature at a frequency of 3.8 GHz (7.9 cm wavelength), during the austral spring of 1989, obtaining a brightness temperature, T(CMB), of 2.64 +/- 0.07 K (68% confidence level). The new result is in agreement with our previous measurements at the same frequency obtained in 1986-88 from a very different site and has comparable error bars. Combining measurements from all years we obtain T(CMB) = 2.64 +/- 0.06 K.
