英文摘要	In this paper, we investigate gravitational waves (GWs) from the axionlike particle inflation by applying the multinature inflation model. The model parameter n determines the exit way of inflation, the number of phase transitions (PTs), and the number of multiples of inflation. In the inflation exit with PTs, there is a lower bound for parameter n to reach the corresponding multiples of inflation, but the magnitude of n is negligible for the physical observations, such as n(s), r, and omega(GW)h(2). GWs can be generated in two ways for the inflation exit with PTs, one derives from quantum fluctuations, which dominate the low-frequency regions, and these GWs can be detected by the Ultimate-Decigo detector at around 10(-1) Hz. However, the other one derives from PTs, which dominate the high-frequency regions, and it is expected to be detected by the future higher-sensitivity 3DSR GW detector.
