摘　　要：给出了本质正矩形张量的定义并研究了他的有关性质,在此基础上定义了弱正矩形张量.The real rectangular tensors arise from the strong ellipticity condition problem in solid mechanics and the entanglement problem in quantum physics. It is defined essentially positive rectangular tensors, systematically studied properties of essentially positive rectangular tensors, and gived some conclusions related to the geometric simplicity of the largest singular value of nonnegative rectangular tensors.Furthermore the weakly positive rectangular tensors is defined and studied.
