Gravitational wave standard sirens and cosmological parameter
  measurement
  Gravitational wave standard sirens can be used to arbitrate the $H_0$ tension
within the following several years. In the future, the observation of
gravitational wave standard sirens would be developed into a powerful new
cosmological probe because they can play an important role in breaking
parameter degeneracies formed by other observations. Therefore, gravitational
wave standard sirens are of great importance for the future accurate
measurement of cosmological parameters.
