  In this paper, we present the detailed analysis of recurrent homologous jets
originating from an emerging negative magnetic flux at the edge of an Active
Region. The observed jets show multi-thermal features. Their evolution shows
high consistence with the characteristic parameters of the emerging flux,
suggesting that with more free magnetic energy, the eruptions tend to be more
violent, frequent and blowout-like. The average temperature, average electron
number density and axial speed are found to be similar for different jets,
indicating that they should have been formed by plasmas from similar origins.
Statistical analysis of the jets and their footpoint region conditions reveals
a strong positive relationship between the footpoint-region total 131 {\AA}
intensity enhancement and jets' length/width. Stronger linearly positive
relationships also exist between the total intensity enhancement/thermal energy
of the footpoint regions and jets' mass/kinetic/thermal energy, with higher
cross-correlation coefficients. All the above results, together, confirm the
direct relationship between the magnetic reconnection and the jets, and
validate the important role of magnetic reconnection in transporting large
amount of free magnetic energy into jets. It is also suggested that there
should be more free energy released during the magnetic reconnection of blowout
than of standard jet events.
