摘要：

In this work, we calculated two models' gravitational wave spectrum from the bubble collision in the cosmological first-order phase transition. The first one corresponds to a scalar field model without gravitation, while the second corresponds to a scalar field model with gravitation. Compared with the sensitivity curves from the LISA space-based interferometer, we find the stochastic gravitational-wave background from bubble collision of the two models has a different amplitude and can be observed in future observation. Especially, we used a numerical way to calculate the speed and frequency of the bubble wall before and after the collision, respectively. We show that the difference between the amplitudes of those spectra of the two models can be distinguished in the future space-based experiment.
