摘要：

The balloon-borne experiment ULISSE, operating at millimetric wavelengths, set a very stringent upper limit to the differential (single-subtracted) cosmic microwave background anisotropy at 6-degrees: DELTA-T less than or similar 35-mu-K. This limit is obtained with a likelihood-ratio analysis; the size and power of the test are 5% and less than or similar 80%, respectively. We discuss the implications of this upper bound for flat cold dark matter and open baryonic-dominated cosmologies.
