abstract = {<p style="text-align: justify;">In this paper, we give all the first integrals of the quintic systems
which have a uniform isochronous center, and use them to determine the qualitative behavior of the periodic solutions of their equivalent non-autonomous
systems. Meanwhile, we clearly describe the local phase portraits of singularity
at infinity.</p>},
