    Turbulence was formed in a rotating circular cylinder by force, and velocity distributions of three directions and Reynolds shearing stress were measured with hotwire anemometer. On the one hand, we solved numerically the equation of an angular momentum. Comparing with the experimental results, calculated resultscoincide with its Supposing Reynolds shearing stress of tangential direction differs from the expression used up to now,experimental shearing Stress agrees much with the calculated results using τ=ρε θv/θ
