给出了非负张量的一些性质，将随机矩阵的某个性质推广到了随机张量，且证明了满足一定条件的非负张量谱半径的复几何单性，并进一步给出了有关非负弱不可约张量的一些结论。%In this paper , some conclusions about nonnegative tensors were given .Extended some certain property stochastic matrices into stochastic tensors , proved the geometric sim-plicity of the nonnegative tensors spectral radius in the complex field , and furthermore gave some conclusions about nonnegative weakly irreducible tensors .
