We study the Non-Linear Born-Infeld(NLBI) scalar field model and quintessencemodel with two different potentials($V(\phi)=-s\phi$ and ${1/2}m^2\phi^2$). Weinvestigate the differences between those two models. We explore the equationof state parameter w and the evolution of scale factor $a(t)$ in both NLBIscalar field and quintessence model. The present age of universe and thetransition redshift are also obtained. We use the Gold dataset of 157 SN-Ia toconstrain the parameters of the two models. All the results show that NLBImodel is slightly superior to quintessence model.Comment: 17 pages, 10 figures, some references adde
