| Abstract: | The stability problem of the Lorenz-like system with the single time-delay is studied in this paper. We analyze the stability and Hopf bifurcation condition of the system at its zero balance by using the theory of the canonical form, and the correctness of the obtained conclusion is verifled by numerical simulation, which extends the research achievements in literature 5]. |

| Keywords: | a single time-delay Lorenz-like system stability Hopf bifurcation |
