  The capture of compact objects by massive black holes in galaxies or dwarf
galaxies will generate short gravitational wave signals, called
extreme-mass-ratio bursts (EMRBs), before evolving into extreme-mass-ratio
inspirals. Their detection will provide an investigation of the black hole
properties and shed light on astronomy and astrophysics. In this work, we
investigate the detection number of the TianQin observatory on EMRBs. Our
result shows that TianQin can detect tens of EMRBs events during its mission
lifetime. For those detected events, we use the Fisher information matrix to
quantify these uncertainties in the inference of their parameters. We consider
the possible network of TianQin+LISA and study how a network can improve
parameter estimation. The result shows that, for most sources, the CO mass, the
MBH mass, and the MBH spin can be determined with an accuracy of the order
$10^{-1}$ and the sky localization can be determined with an accuracy of 10
square degrees. We further explore the gravitational wave background generated
by those unsolved EMRBs and conclude that it is about $10^6$ times weaker than
TianQin's sensitivity and thus it can be ignored.
