Abstract：
Using the data collected with Beijing Spectrometer (BES),we have measured the total cross section for e⁺e^－ annihilation into hadronic final states around center-of-mass energy 3.55 GeV. The values of R,σ (e⁺e^－→hadrons)/σ(e⁺e^－→μ⁺μ^－),are determined with smaller error than the previous result by a factor of two.
